Japan team offers fertility hope with stem cell eggs

By Uncategorized

Hopes of a cure for infertility in humans were raised Friday after Japanese stem cell researchers announced they had created viable eggs using normal cells from adult mice.

The breakthrough raises the possibility that women who are unable to produce eggs naturally could have them created in a test tube from their own cells and then planted back into their body.

A team at Kyoto University harvested stem cells from mice and altered a number of genes to create cells very similar to the primordial germ cells that generate sperm in men and oocytes -- or eggs -- in women.

They then nurtured these with cells that would become ovaries and transplanted the mixture into living mice, where the cells matured into fully-grown oocytes.

They extracted the matured oocytes, fertilised them in vitro -- in a test tube -- and implanted them into surrogate mother mice.

The resulting mice pups were born healthy and were even able to reproduce once they matured.

Writing in the US journal Science, which published the findings, research leader professor Michinori Saito said the work provided a promising basis for hope in reproductive medicine.

"Our system serves as a robust foundation to investigate and further reconstitute female germline development in vitro, not only in mice, but also in other mammals, including humans," he said.

Saito cautioned that this was not a ready-made cure for people with fertility problems, adding that a lot of work remained.

"This achievement is expected to help us understand further the egg-producing mechanism and contribute to clarifying the causes of infertility," he told reporters.

Multiple miRNA Markers Associated with Angiogenesis and Tissue Injury Repair Expressed in Cytori’s Cell Therapy

By Uncategorized

SAN DIEGO--(BUSINESS WIRE)--

Cytori Therapeutics (CYTX) announced that three oral presentations related to its cell therapy are being presented today at the 10th annual International Federation for Adipose Therapeutics and Sciences meeting. The findings provide insights into the mechanisms-of-action for Cytoris cell therapy. One study identified high levels of micro-RNA (miRNA) markers in human tissue thought to play a role in the repair of tissue injury resulting from ischemia, or lack of blood flow. Two additional characterization and comparative analysis studies on human tissue reaffirmed cellular characteristics of Cytoris cell therapy and distinguished the safety, viability and cell make-up as compared to cell outputs derived from alternate approaches.

Results from all three studies have important implications for how the cells repair injured tissue and on the safety and viability of cell-based treatments derived from adipose tissue, said John Fraser, Ph.D., Chief Scientist of Cytori Therapeutics. Mechanisms identified in our miRNA analysis are consistent with our prior clinical and preclinical data, which suggest these mechanisms include angiogenesis, immune-modulation, and remodeling and wound repair. The miRNA study provides baseline data, which we can apply to our U.S. ATHENA clinical trial in refractory heart failure patients and other activities including our recently announced contract with BARDA for thermal burns.

In one study, miRNA profiles were assessed in adipose-derived stem and regenerative cells (ADRCs) derived from human tissue samples. The purpose was to determine which miRNA markers are expressed, miRNA variability from patient to patient, cellular functions of miRNA, and to establish a baseline miRNA population on healthy patients to compare against patients with a specific disease. Specifically, miRNA markers associated with angiogenesis, tissue remodeling and wound repair, and modulation of the immune response were found to be highly represented in ADRCs.

Our two additional characterization and comparative analysis studies evaluated alternate processing techniques and reaffirmed our proprietary enzyme-based process using Celution is the clear gold standard, added Dr. Fraser. If the composition of a cell population extracted from adipose tissue by an alternative process is not equivalent to Cytoris ADRC population, one cannot claim equivalence to ADRCs in terms of safety or efficacy in preclinical or clinical outcomes.

The characterization and comparative analysis studies reaffirmed the high cell yield and viability as well as the heterogeneity in Cytoris cell therapy approach. Cytoris cells are derived with a proprietary formulation of clinical grade enzymes which break up the connective tissue and which are removed at the end of the process. Cytoris cell mixture includes adipose-derived stem cells, based on the measure of colony forming units, and a high yield of CD34+ cells. By contrast, data in these studies showed that alternate approaches such as ultrasound or emulsification, contained little to no adipose-derived stem cells, a high concentration of red and white blood cells, and did not meet the key criteria for safe clinical use.

About Cytori

Cytori Therapeutics, Inc. is developing cell therapies based on autologous adipose-derived regenerative cells (ADRCs) to treat cardiovascular disease and repair soft tissue defects. Our scientific data suggest ADRCs improve blood flow, moderate the immune response and keep tissue at risk of dying alive. As a result, we believe these cells can be applied across multiple "ischemic" conditions. These therapies are made available to the physician and patient at the point-of-care by Cytori's proprietary technologies and products, including the Celution system product family. http://www.cytori.com

Stem Cell Transplant May Spur Heart Disease Risk: Study

By Stem Cell Treatment

WEDNESDAY, Oct. 3 (HealthDay News) -- People who undergo the transplantation of stem cells taken from bone marrow, circulating blood or umbilical cord blood are more likely to develop risk factors for heart disease, such as high blood pressure, diabetes and high cholesterol, a new study contends.

Researchers from the American Society of Hematology noted that patients who were treated with chemotherapy or radiation before such a transplant -- called a "hematopoietic cell transplant," or HCT -- had a significantly higher risk for heart disease later in life.

"While we know that heart disease is a real concern for long-term HCT survivors, small sample sizes and a lack of long-term follow-up in previous studies have only allowed us to look at a small piece of the puzzle of how this chronic condition develops in these patients," the study's first author, Dr. Saro Armenian, medical director of the Pediatric Survivorship Clinic in the Childhood Cancer Survivorship Program at City of Hope in Duarte, Calif., said in a society news release.

"Our study sought to better determine the specific factors before and after transplant that can lead to heart disease in a large group of transplant recipients," Armenian explained.

In conducting the study, the researchers examined the medical records of nearly 1,900 hematopoietic cell transplant recipients to identify factors that could affect their development of risk factors for heart disease. The transplants occurred between 1995 and 2004, and the patients survived for at least one year after the treatment.

The investigators considered the patients' exposure to chemotherapy or radiation before the transplant, the type of hematopoietic cell transplant and whether they were treated for a serious transplant complication known as graft-versus-host disease.

Using the U.S. National Health and Nutrition Examination Survey, the researchers also projected heart disease risk factor rates for the general population.

The study found that high blood pressure, diabetes and high cholesterol were more common among long-term survivors of the blood-forming stem cell transplants.

The risk for developing diabetes was 1.5 times higher for hematopoietic cell transplant survivors who underwent total body radiation. Their risk for high cholesterol was 1.4 times higher. The researchers noted this was true regardless of the type of blood-forming stem cell transplant the patient received.

Although it's unclear why total body radiation increased these patients' risk for diabetes and high cholesterol, previous studies have shown that abdominal radiation may contribute to insulin resistance and an increase in belly fat among cancer patients.

Mouse stem cells used to produce eggs, Japanese scientists say

By Stem Cell Doctors

Reaching a long-sought milestone, Japanese researchers have demonstrated in mice that eggs and sperm can be grown from stem cells and combined to produce healthy offspring, pointing the new treatments for infertility.

If the achievement can be repeated in humans and experts said they are optimistic that such efforts will ultimately succeed the technique could make it easier for women in their 30s or 40s to become mothers. It could also help men and women whose reproductive organs have been damaged by cancer treatments or other causes.

About one in 10 American women of childbearing age have trouble becoming or staying pregnant, and more than one-third of infertile couples must contend with a medical problem related to the prospective father, according to the national Centers for Disease Control and Prevention in Atlanta.

Using current technology, only about one-third of attempts at assisted reproduction result in live births, CDC data show. Scientists, doctors and patients would like to boost that percentage.

"These studies provide that next level of evidence that in the future fertility could be managed with stem cell intervention," said Teresa Woodruff, chief of fertility preservation at Northwestern University Feinberg School of Medicine.

The prospect of using stem cells to grow new eggs is particularly tantalizing, since women are born with a set number and don't make more once they are gone. In a sense, the therapy would allow them to turn back their biological clocks, said Stanford stem cell researcher Renee A. Reijo Pera, who studies reproduction.

"This is a get-them-back strategy," she said.

Dr. Mitinori Saitou and colleagues at Kyoto University detailed how they generated the functional mouse eggs in a report published online Thursday by the journal Science. Last year, the researchers reported in the journal Cell that they had done the same thing with mouse sperm.

In both cases, the team started with embryonic stem cells, which have the potential to develop into all of the different types of cells in the body.

The scientists exposed the embryonic stem cells to stimuli that coaxed them to become egg and sperm precursors.

Stem cells could lead to future fertility treatments, study says

By Stem Cell Doctors

In a long-sought achievement, Japanese researchers have demonstrated in mice that both eggs and sperm can be grown from stem cells and combined to produce healthy offspring, pointing the way to a new avenue for fertility treatments.

If the milestone accomplishment can be repeated in humans -- and experts said they are optimistic that such efforts will ultimately succeed -- the technique could make it easier for women in their 30s or 40s to become mothers. It could also help men and women whose reproductive organs have been damaged by cancer treatments or other causes.

The prospect of using stem cells to grow new eggs is particularly tantalizing, because women are born with a set amount and don't make more once they are lost. In a sense, the therapy would allow them to turn back their biological clocks, said Stanford stem cell researcher Renee A. Reijo Pera, who studies reproduction.

"This is a get-them-back strategy," she said.

Using stem cells to create sperm and eggs in mice is a feat researchers have attempted, without much success, for more than a decade, said Dr. George Q. Daley, a leading stem cell researcher at Children's Hospital in Boston.

Dr. Mitinori Saitou and colleagues at Kyoto University detailed how they generated the functional mouse eggs in a report published online Thursday by the journal Science. Last year, the researchers reported in the journal Cell that they had done the same thing with mouse sperm.

Baby Mice Born from Eggs Made from Stem Cells

By Stem Cell Treatment

Stem cells have been coaxed into creating everything from liver cells to beating heart tissue. Recently, these versatile cells were even used to make fertile mouse sperm, suggesting that stem cell technology might eventually be able to play a role in the treatment of human infertility.

Now two types of stem cells have been turned into viable mouse egg cells that were fertilized and eventually yielded healthy baby mice. Details of this achievement were published online October 4 in Science.

Katsuhiko Hayashi, of Kyoto Universitys School of Medicine, were able to create the eggs with embryonic stem cells as well as with induced pluripotent stem cells (formed from adult cells).

The team started with female embryonic stem cells and then coaxed them genetically to revert to an earlier developmental stage (primordial germ cell-like cells). These cells were blended with gonadal somatic cells, important in the development of sexual differentiation, to create reconstituted ovaries. The researchers then transplanted these cultured assemblages into female mice (in either the actual ovary or the kidney) for safekeeping and to allow the stem cells to mature into oocytes in a natural environment.

To test the eggs fertility, the new oocytes were removed from the mice for an in vitro fertilization with mouse spermand then re-implanted into the female mice. The experimental females went on to bear normally developing and fertile offspring. The procedure was then also performed successfully with induced pluripotent stem cells from adult skin cells with similar results.

Our system serves as a robust foundation to investigate and further reconstitute female germline development in vitro, the researchers noted in their paper, not only in mice, but also in other mammals, including humans.

Todd Akin’s ‘War on Women’ Started Seven Years Ago

By Stem Cell Doctors

Rep. Todd Akin, R-Mo., ignited a firestorm Aug. 19 when he claimed women who are the victims of "legitimate rape" biologically don't carry a baby to term. Voters in Missouri had a heads-up moment seven years ago when Akin made an ultra-conservative speech on the floor of Congress regarding embryonic stem cell research. Three years later, the representative made odd remarks about abortion doctors.

Akin's so-called "war on women" didn't begin in August. It may have started seven years ago.

What exactly did Akin say on the floor of the House of Representatives?

Slate.com found two videos of the representative speaking before his fellows in Congress. In May 2005, Akin slammed embyronic stem cell research. The representative claimed to be telling a story his daughter wrote about how a child is named "5-25-61-B" instead of a human name. Akin further likened a mother's womb to "climate control" for the "unique information that defines a person."

A second video Slate found on C-SPAN was from January 2008. Akin slammed abortion doctors as people who have a "culture of death" along with "all kinds of other law-breaking: not following good sanitary procedure, giving abortions to women who are not actually pregnant, cheating on taxes misuse of anesthetics so that people die or almost die."

What has been the reaction to these videos?

Dan Amira of New York Magazine found a Chicago Tribune story that seems to corroborate Akin's testimony on abortion doctors . Arnold Bickham had his license revoked for 18 months beginning in 1979 for performing abortions on women "not pregnant and sometimes not fully under anesthesia."

The Slate article notes Akin or his daughter may have read a book entitled "Never Let Me Go ." The novel focuses on children who grow up to be clones designed to be harvested for their organs. The piece, written in 2005, is by Kazuo Ishiguro. Akin's speech denouncing cloning and stem cell research was made the same year "Never Let Me Go" was published.

How do these new revelations change the Missouri Senate race?

Slate published an article Tuesday evening regarding Akin's chances of winning the statewide vote. Despite his comments, voter Dee Eukel supports Akin even though she was the victim of rape. Eukel told the media outlet, "I understand [legitimate rape] because I was a victim. And our local prosecutor told me: We best accept a plea bargain because we can't get a prosecution on rape."

Study suggests stem cell transplant survivors at increased risk of developing heart disease

By Stem Cell Clinic

Public release date: 3-Oct-2012 [ | E-mail | Share ]

Contact: Claire Gwayi-Chore cgwayi-chore@hematology.org 202-776-0544 American Society of Hematology

(WASHINGTON, October 3, 2012) New research appearing online today in Blood, the Journal of the American Society of Hematology (ASH), suggests that long-term survivors of hematopoietic cell transplants (HCT) are at an increased risk of developing heart disease risk factors such as high blood pressure, diabetes, and high cholesterol when compared to the general population. These risk factors, combined with exposure to pre-HCT therapy, contribute to a noticeably increased risk of heart disease over time.

HCT, the transplantation of blood-forming stem cells from the bone marrow, circulating blood, or umbilical cord blood, is the primary treatment option for many patients with blood disorders. The healthy transplanted stem cells replace patients' damaged cells that caused their illness. Advances in transplantation strategies have contributed to marked improvements in patient outcomes, resulting in a growing number of long-term transplant survivors, many of whom struggle with one or more chronic, post-transplant health conditions. Previous researchers have speculated that survivors' exposure to potentially heart damaging pre-transplant chemotherapy and radiation or treatment for a life-threatening transplant complication known as graft-versus-host-disease (GVHD) can increase their risk of developing heart disease and its associated risk factors. However, there have been limited data to validate the contribution of pre-conditioning chemotherapy or radiation and GVHD to the eventual development of heart disease in long-term HCT survivors.

"While we know that heart disease is a real concern for long-term HCT survivors, small sample sizes and a lack of long-term follow up in previous studies have only allowed us to look at a small piece of the puzzle of how this chronic condition develops in these patients," said Saro H. Armenian, DO, MPH, the study's first author, Assistant Professor in the Division of Outcomes Research, and Medical Director of the Pediatric Survivorship Clinic in the Childhood Cancer Survivorship Program at City of Hope in Duarte, CA. "Our study sought to better determine the specific factors before and after transplant that can lead to heart disease in a large group of transplant recipients."

In order to more thoroughly evaluate heart disease risk and development in HCT recipients, Dr. Armenian and his team of researchers designed a retrospective study to evaluate factors that may affect a survivor's risk of developing high blood pressure, diabetes, and high cholesterol after HCT. These factors included transplant recipients' exposure to pre-transplant chemotherapy and radiation, conditioning therapy for HCT, their type of HCT transplant, and whether they developed and were treated for GVHD post transplant.

To better determine HCT survivors' incidence of high blood pressure, diabetes, and high cholesterol compared to the general population, researchers analyzed medical records of 1,885 patients who underwent a first-time HCT for a blood cancer at City of Hope between 1995 and 2004 and had survived at least one year. The National Health and Nutrition Examination Survey was used to generate expected heart disease risk factor rates for the general population.

Following their analysis, researchers found a higher prevalence of high blood pressure, diabetes, and high cholesterol in long-term HCT transplant survivors when compared to the general population. HCT conditioning with total body radiation was associated with a 1.5-fold increase in risk of developing diabetes and a 1.4-fold increase in risk of developing high cholesterol, regardless of HCT type, a finding that validates previous reports from long-term childhood and adult HCT survivors. While the mechanism by which total body radiation increases the risk of diabetes and high cholesterol in HCT recipients is not clear, previous studies have shown that abdominal radiation may contribute to known heart disease risk factors such as insulin resistance and an increase in belly fat in conventionally treated cancer patients. This evidence suggests that radiation-induced pancreatic or liver injury may play a role in an HCT transplant survivor's development of heart disease by increasing their risk for heart disease risk factors.

Next, researchers assessed the role of transplant type on long-term HCT survivors' risk of developing key heart disease risk factors. After reviewing the data, researchers observed that those who had received transplanted stem cells from a donor (allogeneic HCT) were at a significantly higher risk of developing high blood pressure, diabetes, or high cholesterol after transplant than those who had received blood-forming stem cells from their own body (autologous HCT). Over the 10-year study period, 45.3 percent of allogeneic HCT recipients developed high blood pressure, 20.9 percent developed diabetes, and 50.5 percent developed high cholesterol; whereas only 32 percent, 15.9 percent, and 43.3 percent of autologous HCT recipients developed these same conditions, respectively. Transplant recipients who had undergone an allogeneic HCT and who had experienced GVHD had the highest risk of developing heart disease risk factors, researchers concluded; 54.7 percent of this group developed high blood pressure, 25.8 percent developed diabetes, and 52.8 percent developed high cholesterol.

Not only did more allogeneic than autologous HCT recipients develop these heart disease risk factors over this time period, but they also developed them more quickly. Allogeneic HCT recipients developed high blood pressure and high cholesterol both at a median time to onset of 2.5 months, compared with autologous HCT recipients who developed the same conditions at 3.7 years and 1.6 years, respectively. Allogeneic HCT recipients also developed diabetes more than two years earlier than autologous recipients (1.2 year median time to onset for allogeneic HCT recipients vs. 3.3 years for autologous transplant recipients).
