What are the unique properties of stem cells – answers.com

Stem cells differ from other kinds of cells in the body. All stem cells-regardless of their source-have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types.

Stem cells are capable of dividing and renewing themselves for long periods. Unlike muscle cells, blood cells, or nerve cells-which do not normally replicate themselves-stem cells may replicate many times, or proliferate. A starting population of stem cells that proliferates for many months in the laboratory can yield millions of cells. If the resulting cells continue to be unspecialized, like the parent stem cells, the cells are said to be capable of long-term self-renewal.

Scientists are trying to understand two fundamental properties of stem cells that relate to their long-term self-renewal:

Discovering the answers to these questions may make it possible to understand how cell proliferation is regulated during normal embryonic development or during the abnormal cell division that leads to cancer. Such information would also enable scientists to grow embryonic and non-embryonic stem cells more efficiently in the laboratory.

The specific factors and conditions that allow stem cells to remain unspecialized are of great interest to scientists. It has taken scientists many years of trial and error to learn to derive and maintain stem cells in the laboratory without them spontaneously differentiating into specific cell types. For example, it took two decades to learn how to grow human embryonic stem cells in the laboratory following the development of conditions for growing mouse stem cells. Therefore, understanding the signals in a mature organism that cause a stem cell population to proliferate and remain unspecialized until the cells are needed. Such information is critical for scientists to be able to grow large numbers of unspecialized stem cells in the laboratory for further experimentation.

Stem cells are unspecialized. One of the fundamental properties of a stem cell is that it does not have any tissue-specific structures that allow it to perform specialized functions. For example, a stem cell cannot work with its neighbors to pump blood through the body (like a heart muscle cell), and it cannot carry oxygen molecules through the bloodstream (like a red blood cell). However, unspecialized stem cells can give rise to specialized cells, including heart muscle cells, blood cells, or nerve cells.

Stem cells can give rise to specialized cells. When unspecialized stem cells give rise to specialized cells, the process is called differentiation. While differentiating, the cell usually goes through several stages, becoming more specialized at each step. Scientists are just beginning to understand the signals inside and outside cells that trigger each stem of the differentiation process. The internal signals are controlled by a cell's genes, which are interspersed across long strands of DNA, and carry coded instructions for all cellular structures and functions. The external signals for cell differentiation include chemicals secreted by other cells, physical contact with neighboring cells, and certain molecules in the microenvironment. The interaction of signals during differentiation causes the cell's DNA to acquire epigenetic marks that restrict DNA expression in the cell and can be passed on through cell division.

Many questions about stem cell differentiation remain. For example, are the internal and external signals for cell differentiation similar for all kinds of stem cells? Can specific sets of signals be identified that promote differentiation into specific cell types? Addressing these questions may lead scientists to find new ways to control stem cell differentiation in the laboratory, thereby growing cells or tissues that can be used for specific purposes such as cell-based therapies or drug screening.

Adult stem cells typically generate the cell types of the tissue in which they reside. For example, a blood-forming adult stem cell in the bone marrow normally gives rise to the many types of blood cells. It is generally accepted that a blood-forming cell in the bone marrow-which is called a hematopoietic stem cell-cannot give rise to the cells of a very different tissue, such as nerve cells in the brain. Experiments over the last several years have purported to show that stem cells from one tissue may give rise to cell types of a completely different tissue. This remains an area of great debate within the research community. This controversy demonstrates the challenges of studying adult stem cells and suggests that additional research using adult stem cells is necessary to understand their full potential as future therapies.

Squamous Cell Carcinoma in Dogs and Cats – Vet360

Any tumour growing within (dermal), on (epidermal) or even under the skin (subdermal) should be considered a skin tumour. Some skin tumours are benign (i.e., slow-growing, completely curable with complete resection and dont spread) while others are malignant (faster growing, invasive, sometimes incurable, and may spread to other organs). In order to classify what type of tumour you are dealing with, you will need to make a fine needle aspirate or take a biopsy A biopsy can either be incisional or excisional. Whichever course is taken, a microscopic diagnosis must always, always be obtained.

No two tumours of the same kind look the same, but very different cancers can appear similar When tumours are inflamed or infected, the underlying pathology can be masked. This information is very important. If its a cytological or incisional, this information can help guide you as the best approach to cure not only the obvious lump but also manage the precancerous lesions that surround the obvious tumour. Not all skin tumours are best removed surgically! Only very small (1 2 cm on the body or neck, and <1 cm elsewhere) should be removed by excision.

Many clients and vets try to economise by removing small lumps instead of taking the extra step this can drastically alter prognosis, by spreading tumour cells.

Although theoretically any tumour can occur in the skin, we classically think of just a few types when we say skin cancer squamous cell carcinomas (SCC), melanomas, haemangiosarcomas (HSA) and mast cell tumours (MCT).

Actinic Keratosis

Actinic keratosis (AK), also known as solar keratosis or senile keratosis, is a very common lesion occurring in susceptible humans as a result of prolonged and repeated solar exposures. The action of ultraviolet radiant energy, principally UVB, results in damage to the keratinocytes and produces single or multiple, discrete, dry, rough, adherent scaly lesions. These premalignant lesions may, in time, progress to squamous cell carcinomas.

This is very important as a warning sign and should be the first thing you teach clients about. A couple of veterinary-specific manifestations of AK are the comedones or blackheads seen on cats noses (fig 1) and dogs ventra. These lesions can be managed with protection, (fig 2) imiquimod or Photodynamic Therapy (PDT). More on these modalities later.

Squamous Cell Carcinomas

Squamous Cell Carcinomas are the classical skin tumours, caused primarily by long-term to exposure to UV-B radiation. The animals most afflicted white or part-white cats and dogs. Bull Terriers, Staffies, Pit Bulls, Bulldogs and Jack Russells are amongst the dog breeds most often affected. These ex-British breeds enjoy our long, glorious South African summer sun, and tan day after day.

UV-B radiation damages DNA and this damage is cumulative and only partially repairable or reversible. Squamous cell carcinomas can look like nothing more than non-healing crusts, pimples or scabs, or they can form large, raised, ulcerating plaques.

PROGNOSIS

It is important to treat according to the stage presented:

Primary Tumour:

T0 = no tumour

T in situ = Pre-invasive carcinoma (scale, crust)

T1 = tumour <2cm diameter, superficial or exophytic

T2 = tumour 2 5 cm diameter, OR with minimal invasion irrespective of size

T3 = tumour > 5cm diameter, or with invasion of subcutis irrespective of size

T4 = invading fascial, muscle, bone or cartilage, regardless of size

Regional lymph nodes:

N0 = no involvement

N1 = lymphnodeinvolvement

Distant metastasis:

M0 = no metastasis

M1 = evidence of metastasis

Ulceration of the primary tumour is associated with a biologically more aggressive lesion and a poorer prognosis. It is not known why ulcerated primaries have a more aggressive biologic nature. It is not likely due to underestimation of the thickness due to the ulcer crater. Ulcerated lesions tend to be thicker and have a nodular growth pattern, but the increased thickness does not account for the poorer prognosis. However, the depth or width of surface ulceration has been significantly correlated with survival. Other histologic prognosticators include the mitotic indices, whirling and the presence or absence of lymphatic or blood vessel invasion are relevant to prognosis.

Tumours in situ look like nothing more than scaly, scabby skin and offer another earlier warning sign, the best opportunity for cure, and are a wake up call. My preference for this is to use immunotherapy with imiquimod cream, or photodynamic therapy for T in situ and T1 tumours.

T2 tumours which are large but NON invasive (T2 large) also respond well to PDT or radiotherapy, but those that are T2 invasive require surgery or aggressive PDT (only to 5mm depth maximum). Once it gets to T2 invasive or T3+, cure rates using any technique drop to below 40% (from >85%) so teach your pet owners about skin cancer and early aggressive intervention from the first vaccination!

T3 and T1-4N/(any) M0/1 must be referred to a specialist for management. I see huge disasters when GPs approach these with surgery. Dogs are disfigured and then referred when they could have kept penises, mobility or faces with a proper approach from the beginning. An integrated approach using multiple modalities and an understanding of tissue tolerances, treatment sequencing and proper patient surveillance are beyond the scope of general practice. Managing such a patient is often possible, but is an 8 20 week process.

More extensive tumours may require additional surgery, chemotherapy or radiation to achieve good results. Their main importance is that they recur because skin of the ventral abdomen, ears or nose have been damaged. (fig 3) Cutting out squamous cell carcinomas can be like the little Dutch boy plugging the hole in the dyke with a finger another often just pops up elsewhere.

Recurrent SCC may require specialist attention to get under control or cure. In any event, thoracic radiographs should be performed. SCC of the feet (pedal SCC) is far more aggressive and spreads to the lungs earlier than other SCC of the skin, so always attend to any non-healing wound or lump of >1 weeks duration by having it checked using histopathology.

Treatment

Figure 1. White cat with nasal SCC this is the earliest stage the presence of discharge and slight scaling around the nose and eyelids. If treated appropriately at this stage, the prognosis for cure is close to 100%

Figure 2. UV suit UV-resistant suits (obtained from Dr Georgina Crewe), protect the healthy or precancerous skin and are an essential part of post-treatment management

Photodynamic Therapy (PDT) (fig 4) is a technique using the application or injection of photosensitising agents in different concentrations. They accumulate in certain tumours and when subjected to high-fluence (200-300 W/cm2) light of a specific frequency, keyed to the particular molecule being used, the molecules aggregate into unstable complexes that then restabilise by release of various oxygen radicals which cause lipid membrane, protein and DNA damage. Over-treatment causes regional vasoconstriction and side effects, without increase in toxicity; undertreatment achieves little, but aggravates the inflammation. This treatment is effective only in lesions <5mm thick. Treatment is once a monthly, for 1 3 treatments, depending on severity and extent. Pre-cancerous actinic keratosis can also be successfully managed using this technique.

Immunotherapy using Imiquimod (Aldara; 3M), animidazoquinolinamine, is an immune system modulator and possesses both potent antiviral and antitumor activity in animal models and humans. Current theories suggest that imiquimod acts both directly by inducing apoptosis and by inducing secretion of pro-inflammatory cytokines. Imiquimod activates macrophages and other cells via binding to cell surface receptors, such as Toll receptor 7, and thereby induces secretion of pro-inflammatory cytokines such as interferon-a (IFN-a), tumour necrosis factor-a (TNF-a), and interleukin-12 (IL- 12). These cytokines bias towards a Th1-dominant immune response, which in general is associated with inflammation and tissue injury through activated inflammatory leukocytes and with cytolytic activity through CD8+-lymphocytes (Abbas et al 1996). Imiquimod can also induce apoptosis directly in a Bcl- 2-family-dependent manner by downregulating anti-apoptotic genes such as hurpin and HAX-1.

Treatment is applied to lesions Monday to Friday, once daily, for 6 12 weeks; inflammation caused by the treatment can occasionally be severe and require NSAIDs.

I reserve this for small/early/superficial lesions in cats due to the cost of the cream. Clients must wear gloves to protect themselves. Efficacy is reported as about 75%, with a median survival time of 1189 days, although recurrent lesions do seem to respond to the therapy.

5-Fluorouracil use in animals: this drug is rapidly and fatally neurotoxic in cats even as eye drops. In dogs, the tolerance is also very low and if licked it can trigger fatal mucosal sloughing. Dont use in veterinary practice.

CRYOTHERAPY is outdated, painful, disfiguring and has a lower success rate than other therapies mentioned. Do not use this. Poor technique is a major reason for treatment failure; it requires training and experience and is potentially hazardous to the operator.

RADIATION THERAPY: the use of a linear accelerator to deliver high-voltage (4 20 MeV) electrons or photons for the treatment of surface tumours is called teletherapy. This technique has the potential for extreme harm if improperly performed, and all such cases are specialist cases and must be referred to a person with the relevant training. Theres a reason its an entire field of speciality in itself in the US and Europe. It requires a knowledge of radiation physics, radiation biology and management of radiation side effects that cannot be gleaned from a few lectures.

The role of surgery in managing skin tumours.

Surgery is an important part of management of these conditions. For some tumours e.g. BCC, HA/HSA, MCT, a properly-performed excision can be curative. In others, e.g. SCC, the surrounding skin is often also on an anaplastic march that is unstoppable by surgery alone. Surgery then helps debulk larger masses that would not respond as well to wider-field but lower-intensity therapies e.g. imiquimod, PDT, RT. The timing and planning is critical. Discuss this with a specialist BEFORE radiation or PDT PLEASE! Post-surgical fibrosis decreases the efficacy of other modalities! (fig 5)

Figure 3. SCC ear pinna removal This is the degree of surgery required for more advanced SCC of the pinna, and is to be avoided if possible, by appropriate education of the client at first vaccination of the kitten. This sort of cat may be allowed out at night, but not during the daytime.

Figure 4. PDT Patient undergoing photodynamic therapy at Inanda Vets. Basal Cell Carcinomas

Basal cell tumours are a benign tumour that look very similar to SCC, and are quite common in cats in other parts of the world. In dogs, they typically occur around the head and are not unlike canine cutaneous histiocytoma (hence the need for a tissue diagnosis). They are usually single, raised, ulcerated button-like tumours. Surgery alone is normally curative. They can be diagnosed by cytology or histopathology. BCC and SCC are classed together as the Keratinocytic Skin Cancers.

Figure 5. Multiple raised SCC on the ventrum of a dog; the previous surgeries have contributed to scar tissue formation, which makes radiation less effective, and future surgeries more difficult. The widespread nature of the disease means a novel approach must be taken if control is to be achieved. Patients arriving at this stage are major challenges to cure.

Perception of Depth by Michael Kalloniatis and Charles Luu …

Michael Kalloniatis and Charles Luu

Stereopsis

Stereopsis refers to our ability to appreciate depth, that is the ability to distinguish the relative distance of objects with an apparent physical displacement between the objects. It is possible to appreciate the relative location of objects using one eye (monocular cues). However, it is the lateral displacement of the eyes that provides two slightly different views of the same object (disparate images) and allow acute stereoscopic depth discrimination.

Monocular Cues

Several strong monocular cues allow relative distance and depth to be judged. These monocular cues include:

Relative Size: Retinal image size allow us to judge distance based on our past and present experience and familiarity with similar objects. As the car drives away, the retinal image becomes smaller and smaller. We interpret this as the car getting further and further away. This is referred to as size constancy. A retinal image of a small car is also interpreted as a distant car (figure 1).

Figure 1. Relative size. A retinal image of a small car is considered to be distant

Interposition: Interposition cues occur when there is overlapping of objects. The overlapped object is considered further away (figure 2).

Figure 2. Interposition. The blue circle is reported to be closer since it overlaps the red circle

Linear Perspective: When objects of known distance subtend a smaller and smaller angle, it is interpreted as being further away. Parallel lines converge with increasing distance such as roads, railway lines, electric wires, etc (figure 3).

Figure 3. Linear perspective. Parallel lines such as railway lines converge with increasing distance

Aerial Perspective: Relative colour of objects give us some clues to their distance. Due to the scattering of blue light in the atmosphere, creating wall of blue light, distance objects appear more blue (figure 4). Thus distant mountains appear blue. Contrast of objects also provide clues to their distance. When the scattering of light blurs the outlines of objects, the object is perceived as distant. Mountains are perceived to be closer when the atmosphere is clear.

Figure 4. Aerial perspective. Mountains in the distance appear more blue

Light And Shade: Highlights and shadows can provide information about an objects dimensions and depth (figure 5). Because our visual system assumes the light comes from above, a totally different perception is obtained if the image is viewed upside down.

Figure 5. Highlights and shadows provide information about depth

Monocular Movement Parallax: When our heads move from side to side, objects at different distances move at a different relative velocity. Closer objects move against the direction of head movement and farther objects move with the direction of head movement.

Binocular Cues

Stereopsis is an important binocular cue to depth perception. Stereopsis cannot occur monocularly and is due to binocular retinal disparity within Panums fusional space. Stereopsis is the perception of depth produced by binocular retinal disparity. Therefore, two objects stimulates disparate (non-corresponding) retinal points within Panums fusional area.

Fusion describes the neural process that brings the retinal images in the two eyes to form one single image. Fusion occurs to allow single binocular vision. Fusion takes place when the objects are the same. When the objects are different, suppression, superimposition or binocular (retinal) rivalry may occurs. Suppression occurs to eliminate one image to prevent confusion. Superimposition results in one image presented on top of the other image. Binocular rivalry describes alternating suppression of the two eyes resulting in alternating perception of the two images. This usually occurs when lines are presented to the two eyes differ in orientation, length or thickness. An example of binocular rivalry occurs when one eye is presented with a horizontal line and the other eye is presented with a vertical line. Binocular rivalry occurs at the intersection of the lines and some suppression also exists (figure 6)

Figure 6. (a) Binocular rivalry can be demonstrated by placing a pen between yourself and the screen. Keep you eye on the tip of the pen and notice the two bars merge. You may need to slowly move the pen from the screen towards you. (b) Result of (a)

Panums fusional area is the region of binocular single vision. Outside Panums fusional area, physiological diplopia occurs. Using the haplopic method of determining the horopter, Panums area can be determined (figure 7).

Figure 7. Haplopic method of determining the horopter involves locating the region of single binocular vision at a distance of 40cm.Panums fusional area lies between the outer and inner limits of the region of single binocular vision

Retinal disparity: Retinal disparate points are retinal points that give rise to different principal visual direction and diplopia. However, retinal disparity within Panums fusional area (zone of single binocular vision) can be fused resulting in single vision. Retinal disparity is essential for stereoscopic depth perception as stereoscopic depth perception results from fusion of slightly dissimilar images. Due to the lateral displacement of our eyes, slightly dissimilar retinal images result from the different perception of the same object from each eye.

Clinical Tests used to measure Stereopsis

There are two groups of clinical tests used to measure stereopsis. These are the contour stereotests and the random-dot stereotest. Random-dot stereograms were first used by Julesz (1960) to eliminate monocular cues. As there are no contours, depth perception (stereopsis) can only be appreciated when binocular fusion occurs. Two process of stereopsis are used and these are local and global stereopsis. Local stereopsis exists to evaluate the two horizontally disparate stimuli. This process is sufficient for contour stereotests. Global stereopsis is required in random-dot stereogram when the evaluation and correlation of corresponding points and disparate points are needed over a large retinal area.

An example of a contour stereotest used in the clinic is the Titmus Fly Stereotest. In the Titmus Fly Stereotest, horizontal disparity is presented via the vectographic technique (Fricke and Siderov, 1997). When tested a 40 cm the fly has a disparity of 3,600 sec of arc; the disparity of the animals range from 400 100 sec of arc and the disparity of the Wirt rings range from 800 40 sec of arc (figure 8).

Figure 8. Titmus Fly Stereotest

Examples of random-dot stereotests used in the clinic are the Frisby Stereotest, the Randot Stereotest, the Random-dot E Stereotest and the Lang Stereotest. The Frisby Stereotest (figure 9) uses real depth to determine stereoacuity. Three perspex of different thicknesses are used. Four squares of geometric shapes are painted on one side of the perspex. In one of the squares, a circle of these geometric shape is painted on the other side of the perspex. Both the Randot (figure 10) and the Random-dot E uses crossed polarised filters. Disparity is also constructed vectographically. The Randot Stereotest uses modified animals and ring designs with random dot backgrounds to eliminate monocular cues. The Lang Stereotest uses a panographic technique (Fricke and Siderov, 1997) to present disparity, therefore, no filters are required. Patients are required to identify pictures on the Lang Stereotest. The Lang II Stereotest has a monocularly visible shape on it (figure 11).

Figure 11. The Lang II

All the tests provides a measure of stereoacuity by asking the patient to identify the correct target that has stereoscoptic depth (target with disparity). The working distance and interpupillary distance will need to be taken into consideration when calculating stereoacuity. Patients with disturbed binocular vision or different refractive error in one eye, will perform poorly on depth discrimination tests.

Why does my DAB signal disappear so quickly?

Hi everyone,

Great suggestions, thanks for sharing your thoughts. I have tried using fresh dehydrating alcohols, but still got the same results. I may try some of the different mounting media you suggested and a different source of DAB. I have not tried leaving out the differentiation step with acid alcohol. Is there a particular bluing reagent that works best?

The details of my protocol are as follows:

The sections were fixed in Modified Davidsons solution, paraffin embedded, re-hydrated, underwent sodium citrate heat-mediated antigen retrieval for 20 minutes, rinsed in PBS, incubated with 10% normal goat serum in PBS for 1 hour at room temperature, incubated with primary antibody in PBS overnight at 4 degrees C, rinsed in PBS, quenched for endogenous peroxidase in 3% hydrogen peroxidase for 15 minutes, rinsed in PBS, incubated with biotinylated secondary antibody in PBS for 1 hour at room temperature, rinsed in PBS, incubated with avidin and biotinylated horseradish peroxidase complex for 30 minutes, rinsed in PBS, developed with DAB (Invitrogen) for 1-2 minutes, counterstained with hematoxylin, rinsed in water, differentiated in acid alcohol, rinsed in water, blued in 0.2% ammonia water, rinsed in water, dehydrated in three changes of isopropanol, cleared through three changes of xylene, and mounted using Cytoseal XYL.
