Patient dies during procedure

By Stem Cell Treatment

(CNN) -

A Florida cardiologist could have his medical license revoked by state authorities who have accused him of performing illegal stem cell therapy on a patient who died during the procedure.

Florida's Department of Health ordered the emergency suspension of Zannos Grekos' medical license Wednesday, accusing the Bonita Springs doctor of violating an emergency order against using stem cell treatments in Florida and causing the death of an unidentified elderly patient. Grekos can appeal the order.

According to the license suspension order, Grekos performed a stem cell treatment this month on the patient, who was suffering from pulmonary hypertension and pulmonary fibrosis. Both diseases restrict blood flow to the heart.

"During said stem cell treatment, patient R.P. suffered a cardiac arrest and died," the suspension order said.

CNN first investigated Grekos' activities in 2009, when he said he was using stem cell therapy for a company called Regenocyte Therapeutic. His profile, listed on the company's website, describes Grekos as having "extensive experience in the field of stem cell therapy" and says he "was recently appointed to the Science Advisory Board of the United States' Repair Stem Cell Institute."

At the time of CNN's interview, Grekos said he extracted stem cells from patients and then sent the blood to Israel for laboratory processing. That processing, he said, resulted in "regenocytes," which he said would help heal crippling diseases, mostly associated with lung problems.

The president of the International Society of Stem Cell Research, Dr. Irving Weissman, told CNN at the time that "there is no such cell."

"There is nothing called a regenocyte," he said.

After CNN's initial report, Grekos said the name was "advertising" and was not intended to be scientific.

CHICAGO, IL March 8, 2012 Stem cells provide a recurring topic among the scientific presentations at the Genetics Society of America's 53rd Annual Drosophila Research Conference, March 7-11 at the Sheraton Chicago Hotel & Towers. Specifically, researchers are trying to determine how, within organs, cells specialize while stem cells maintain tissues and enable them to repair damage and respond to stress or aging. Four talks, one on Thursday morning and three on Sunday morning, present variations on this theme.

For a fertilized egg to give rise to an organism made up of billions or trillions of cells, a precise program of cell divisions must unfold. Some divisions are "asymmetric": one of the two daughter cells specializes, yet the other retains the ability to divide. Chris Q. Doe, Ph.D., professor of biology at the University of Oregon, compares this asymmetric cell division to splitting a sundae so that only one half gets the cherry. The "cherries" in cells are the proteins and RNA molecules that make the two cells that descend from one cell different from each other. This collecting of different molecules in different regions of the initial cell before it divides is termed "cell polarity."

Dr. Doe and his team are tracing the cell divisions that form a fly's nervous system. "Producing the right cells at the right time is essential for normal development, yet it's not well understood how an embryonic precursor cell or stem cell generates a characteristic sequence of different cell types," he says. Dr. Doe and his team traced the cell lineages of 30 neuroblasts (stem cell-like neural precursors), each cell division generating a daughter cell bound for specialization as well as a self-renewing neuroblast. The dance of development is a matter of balance. Self-renew too much, and a tumor results; not enough, and the brain shrinks.

Tracing a cell lineage is a little like sketching a family tree of cousins who share a great-grandparent except that the great-grandparent (the neuroblast) continually produces more cousins. "The offspring will change due to the different environments they are born into," says Dr. Doe.

Julie A. Brill, Ph.D., a principal investigator at The Hospital for Sick Children (SickKids) in Toronto, investigates cell polarity in sperm cells. These highly specialized elongated cells begin as more spherical precursor cells. Groups of developing sperm elongate, align, condense their DNA into tight packages, expose enzyme-containing bumps on their tips that will burrow through an egg's outer layers, form moving tails, then detach and swim away.

The Brill lab studies a membrane lipid called PIP2 (phosphatidylinositol 4,5-bisphosphate) that establishes polarity in developing male germ cells in Drosophila. "Reducing levels of PIP2 leads to defects in cell polarity and failure to form mature, motile sperm," Dr. Brill says. These experiments show that localization of the enzyme responsible for PIP2 production in the growing end of elongating sperm tails likely sets up cell polarity. Since loss of this polarity is implicated in the origin and spread of cancer, defects in the regulation of PIP2 distribution may contribute to human cancer progression, she adds.

Stephen DiNardo, Ph.D., professor of cell and developmental biology at the Institute for Regenerative Medicine at the University of Pennsylvania, is investigating how different varieties of stem cells in the developing fly testis give rise to germ cells and epithelial cells that ensheathe the germ cells, as well as being able to self-renew. For each of these roles, stem cells are guided by their environment, known as their "niche."

In the fly testis, we know not only the locations of the two types of stem cells whose actions maintain fertility, but of neighboring cells. "We study how these niche cells are first specified during development, how they assemble, and what signals they use. Elements of what we and others learn about this niche may well apply to more complex niches in our tissues," Dr. DiNardo explains.

Nuvilex Points Toward Cell Encapsulation Technology Future to Expand Stem Cell Use for Late Stage Cancer Treatments

By Stem Cell Treatment

SILVER SPRING, Md.--(BUSINESS WIRE)--

Nuvilex, Inc. (OTCQB:NVLX), an emerging biotechnology provider of cell and gene therapy solutions, today discussed the potential use of the companys cell encapsulation technology with modified stem cells to treat late stage cancers.

Stem cell therapy is not new to physicians dealing with blood and bone cancers, with stem cell transplants being an important treatment for growing new bone marrow since the 1970s. Recent studies have indicated the potential for using stem cells across a much broader range of cancers is becoming a reality, mostly a result of advances in cell and molecular biology techniques.

Traditional chemotherapy works by targeting the fast-growing cells common to cancer tumors. Unfortunately, chemotherapeutics dont differentiate between healthy and cancerous cells. Patients suffering from metastatic cancers, where tumors have spread to multiple areas of the body, often have substantial difficulties with the chemotherapy needed to treat their disease.

In one case, researchers at City of Hope and St. Jude Children's Research Hospital may have found a way to treat cancers that have spread throughout the body more effectively. They used genetically modified stem cells to activate chemotherapeutic drugs at the tumor sites, so that normal tissue surrounding the tumor and throughout the body remain relatively unharmed. The stem cells were designed to produce a specific enzyme that converts the nontoxic prodrug into the chemotherapeutic agent. This method also targets the brain tumor treatment to remain localized within the brain, similar to the pancreatic cancer clinical trial carried out by SG Austria, providing for high dosage chemotherapy without affecting surrounding tissues and avoiding the severe side effects normally associated with cancer therapy.

Nuvilex believes that incorporating Cell-in-a-Box encapsulation with this type of genetically modified stem cell, along with the proprietary cancer treatment being acquired, could significantly aid and improve patient outcomes.

Dr. Robert Ryan, Chief Executive Officer of Nuvilex, commented, We are hopeful for the day when late stage cancers can be routinely and safely treated using genetically modified cells like those used in the pancreatic cancer trial, increasing the ability of clinicians to avoid inducing side effects that typically accompany aggressive chemotherapy and/or radiation. Our cell encapsulation technology will enable practitioners to target tumors while preserving the health of the surrounding tissues. We continue to look for leading stem cell and oncology researchers to partner with us as we bring this technology to market.

About Nuvilex

Nuvilex, Inc. (OTCQB:NVLX) is an emerging international biotechnology provider of clinically useful therapeutic live encapsulated cells and services for encapsulating live cells for the research and medical communities. Through our effort, all aspects of our corporate activities alone, and especially in concert with SG Austria, are rapidly moving toward completion, including closing our agreement. One of our planned offerings will include cancer treatments using the companys industry-leading live-cell encapsulation technology.

Doctor's license suspended after patient's death

By Stem Cell Treatment

BONITA SPRINGS, FL -

The state Surgeon General has issued an emergency suspension of the license of Dr. Zannos Grekos for providing a stem cell treatment to a patient contrary to previous restrictions placed on his license. The patient died during the treatment.

According to the emergency suspension order, in February 2011 Dr. Grekos was ordered not to perform any stem cell treatments on patients.

On March 2, 2012, Grekos is accused of treating an elderly man with pulmonary hypertension and pulmonary fibrosis with stem cells.

The suspension order says Grekos harvested tissue from the patient's abdomen that commonly contains stem cells. That tissue was sent to a lab to have the stem cells concentrated.

Those concentrated stem cells were then injected into the patient's bloodstream, according to the order.

The patient died of cardiac arrest during the treatment.

Because the stem cell treatment violated previous restrictions on Grekos' license, the state requested the emergency suspension of his license.

One section of the emergency suspension order states, "Nothing short of the immediate suspension of Dr. Grekos' license to practice medicine would be sufficient to protect the public from the danger of harm presented by Dr. Grekos."

Stem cell treatment tricks immune system into accepting donor organs, study shows

By Stem Cell Treatment

By Julie Steenhuysen

CHICAGO Scientists have found a way to trick the immune system into accepting organs from a mismatched, unrelated organ donor, a finding that could help patients avoid a lifetime of drugs to prevent rejection of the donated organ.

Of eight kidney transplant patients who have been treated with this new approach, five have managed to avoid taking anti-rejection drugs a year after their surgery, according to the study published on Wednesday in Science Translational Medicine.

And one patient, 47-year-old Lindsay Porter of Chicago, is completely free of anti-rejection drugs nearly two years after her kidney transplant.

This new approach would potentially offer a better quality of life and fewer health risks for transplant recipients

I hear about the challenges recipients have to face with their medications and it is significant. Its almost surreal when I think about it because I feel so healthy and normal, she said in a statement.

With conventional organ transplants, recipients need to take pills to suppress their immune systems for the rest of their lives. These drugs can cause serious side effects, including high blood pressure, diabetes, infection, heart disease and cancer.

This new approach would potentially offer a better quality of life and fewer health risks for transplant recipients, Dr. Suzanne Ildstad, director of the Institute of Cellular Therapeutics at the University of Louisville in Kentucky, who developed the new approach, said in a statement.

But some experts say the procedure, in which patients undergo a bone marrow transplant from an unmatched organ donor, is too risky, especially given the relative safety of kidney transplants.

We have to think about the risks and benefits. Since the current treatment is so stable, it really has to be safe, said Dr. Tatsuo Kawai, a transplant surgeon at Harvard Medical School, who wrote a commentary on the new approach in the journal.

Florida suspends doctor accused of illegal stem cell therapy

By Stem Cell Treatment

By David Fitzpatrick and Drew Griffin, Special Investigations Unit

updated 1:34 PM EST, Thu March 8, 2012

Dr. Zannos Grekos, seen here in 2009, could have his license suspended.

STORY HIGHLIGHTS

(CNN) -- A Florida cardiologist could have his medical license revoked by state authorities who have accused him of performing illegal stem cell therapy treatment on an elderly patient who died during the procedure.

Florida's Department of Health ordered the emergency suspension of Dr. Zannos Grekos' medical license Wednesday, accusing the Bonita Springs doctor of violating an emergency order against using stem cell treatments in Florida and allegedly causing the death of an unnamed elderly patient. Grekos can appeal the order.

According to the license suspension order, Grekos performed a stem cell treatment earlier this month on the patient, who was suffering from pulmonary hypertension and pulmonary fibrosis. Both diseases restrict blood flow to the heart.

"During said stem cell treatment, patient R.P. suffered a cardiac arrest and died," the suspension order said.

CNN first investigated Grekos's activities in 2009 and, at that time, he said he was using stem cell therapy for a company he called Regenocyte Therapeutic. His profile, listed on the company's website, describes Grekos as having "extensive experience in the field of stem cell therapy" and says he "was recently appointed to the Science Advisory Board of the United States' Repair Stem Cell Institute."

At the time of CNN's interview, Grekos said he extracted stem cells from patients and then sent the blood to Israel for laboratory processing. That processing, he said, resulted in "regenocytes," which he claimed would help heal crippling diseases, mostly associated with lung problems.

Eastday-Student who twice backed out of cell donation divides opinion

By Stem Cell Medical Center

A SHANGHAI student who registered as a stem cell donor but then twice backed out of donating at the last moment has found herself at the center of public debate.

The would-be recipient, a leukemia patient in neighboring Jiangsu Province, had already received medication to stop blood-forming functions in preparation for the transplant when the intended donor pulled out.

It was said that the would-be donor, who has not been named, had faced pressure from her family not to go ahead with the procedure.

The incident has stirred up discussion online, with some web users accusing the student of putting the patient's life in danger through her actions.

Some argued that donors should be legally prevented from backing out once the intended recipient has been given preparatory medication.

However, local medical officials said that donations should be based on freewill and that a donor must be allowed to change his or her mind.

The 23-year-old leukemia patient, Jiang Jing, is being treated in a hospital in Suzhou. As an emergency solution, a partial match was found yesterday using a sample from the Shanghai Stem Cell Blood Bank and cells from Jiang's mother. The success rate is likely to be around 60 percent, local doctors told Shanghai Daily.

Jiang was diagnosed with leukemia last April and a full match was found with the Shanghai college student who had registered as a donor with the Red Cross in the city.

The transplant had been scheduled for Tuesday and the patient had been receiving medication since late last month to stop her body forming blood cells.

But last Thursday, the donor said she did not want to proceed.

Stem Cells Help Kidney-Transplant Patients Skip Rejection Drugs in Study

By Stem Cell Medicine

By Michelle Fay Cortez - Wed Mar 07 19:16:55 GMT 2012

Kidney transplant patients given a mixture of stem cells from their organ donor were able to quit taking anti-rejection medicine in a small study, suggesting that life-long reliance on the toxic drugs may be avoidable.

Five of eight patients treated were able to stop taking about a dozen pills a day to suppress their immune systems. The drugs, which prevent rejection and stop tissue from a donated kidney from attacking the patient, can damage the transplant and cause diabetes, infections, heart disease and cancer.

The breakthrough, reported in the journal Science Translational Medicine, mixed stem cells from the donors infection-fighting immune system with the patients natural immune system. The result enabled tissue from both to co-exist in the transplant patient without either being seen as foreign by the immune system, researchers said.

The results may potentially have an enormous, paradigm- shifting impact on solid-organ transplantation, wrote James Markmann and Tatsuo Kawai from Massachusetts General Hospital in Boston, in an editorial accompanying the study. Although only a taste of things to come, few transplant developments in the past half-century have been more enticing than these that put transplantation tolerance within our grasp.

The findings are particularly striking since the patients werent perfect tissue matches with the living donors. The mismatch traditionally makes it more difficult for the donated organ to survive since the patients immune system perceives the unfamiliar tissue as a threat.

Its been a longstanding goal in transplantation to achieve tolerance, to get the recipient to see the donor organ as part of itself, said Joseph Leventhal, a surgeon at Northwestern Memorial Hospital in Chicago and the lead author. A road to tolerance now exists, he said.

Having two immune systems blend into one is called a chimerism. The long-lasting effect seen in the study may stem from the manipulation of stem cells taken from the donor in advance of the surgery, according to the report.

The cells were sent to Suzanne Ildstad, director of the Institute of Cellular Therapeutics at the University of Louisville in Kentucky. There facilitating cells that help transplants take hold were identified and used to enrich the mixture, which was given to the patient the day after surgery.

The researchers didnt provide details on how they crafted the stem cell mix, which may make it difficult for other investigators to confirm the findings, Markmann and Kawai wrote.
