SUNDAY, Feb. 26 (HealthDay News) -- Researchers report that they've isolated stem cells from adult human ovaries that can mature into eggs that may be capable of fertilization. The lab findings, which upend longstanding scientific theory, could potentially lead to new reproductive technologies and possibly extend the years of a woman's fertility. It was long believed that women were born with a lifetime supply of eggs, which was depleted by menopause. But a growing body of research -- including a new paper from Massachusetts General Hospital -- suggests egg production may continue into adulthood. The study is published in the March issue of Nature Medicine. "Fifty years of thinking, in every aspect of experiments, of interpreting the results, and of the clinical management of ovarian function and fertility in women was dictated by one simple belief that turns out to be incorrect," said lead study author Jonathan Tilly, director of the hospital's Vincent Center for Reproductive Biology. "That belief was the egg cell pool endowed at birth is a fixed entity that cannot be renewed." Dr. Avner Hershlag, chief of the Center for Human Reproduction at North Shore-LIJ Health System in Manhasset, N.Y., said the study is "exciting" but emphasized … Continue reading →

NEWARK, Calif., Feb. 27, 2012 (GLOBE NEWSWIRE) -- StemCells, Inc. (Nasdaq:STEM - News) today announced that it will participate in the Qatar International Conference on Stem Cell Science and Policy, which is being held in Qatar from February 27 to March 1, 2012. The Company, which is the leader in development of cell-based therapeutics for central nervous system disorders, was specifically invited by the conference's sponsors, the State of Qatar and Amir of Qatar His Highness Sheikh Hamad bin Khalifa Al-Thani, as well as the James A. Baker III Institute for Public Policy of Rice University, and is the only company to be invited. Ann Tsukamoto, Ph.D., StemCells' Executive Vice President, Research and Development, will make a presentation on the clinical translation of human neural stem cells. StemCells was the first company to receive authorization from the US Food and Drug Administration to conduct a clinical trial of purified human neural stem cells, and the Company is currently conducting two clinical trials with a third anticipated to start later this year. Dr. Tsukamoto will also be the moderator of the panel session on neurological disorders, which is scheduled to be held on March 1 from 9:30 a.m. to 11:00 a.m. … Continue reading →

There is a tremendous opportunity in genetic medicine for innovation and for new players to make significant contributions, because it is still experimental, noted biologist and Nobel Laureate Dr David Baltimore said yesterday. “Today, it is mainly the province of biotechnology companies and universities, not big pharmaceutical companies,” he observed in a keynote presentation at the Qatar International Conference on Stem Cell Science and Policy 2012. There are new genetic tools available – though they are still experimental - to treat diseases which involve adding, subtracting or modifying genes in the cells of the body. “However, they are powerful tools and I am confident they will be an important part of the medicine of the future,” he said. Speaking on ‘The hematopoietic stem cell (HSC) as a target for therapy against cancer and Aids,’ Dr Baltimore explained that HSCs are one of the few cell types routinely used for bone marrow transplant. The HSCs are easily accessible, retroviruses can be used to carry genes into these stem cells, the genes are then expressed in all of cells that derive from the HSC and can correct inherited defects and bring genes that perform therapy under a programme called engineering immunity. “Though … Continue reading →

The latest discoveries and promises of stem cell research and the development of new therapeutic approaches for a variety of diseases will be in focus at the Qatar International Conference on Stem Cell Science and Policy 2012 which begins today. The four-day event, being held at Qatar National Convention Centre, is a milestone in Qatar Foundation’s ongoing collaboration with the James A Baker III Institute for Public Policy at Rice University, Houston, Texas, US. The aim of QF’s joint initiative with the Baker Institute’s International Programme on Stem Cell Science Policy is to develop stem cell research in Qatar as well as to find ways to address the shared challenges of community support for stem cell research in Doha and Houston. To accomplish this goal, the programme has supported several events since its inception, including meetings, workshops, and training programmes in both cities. The conference, which brings together eminent international as well as regional scientists, ethicists and policymakers, will also present the developed policy options that account for cultural, ethical and religious factors. The event will draw attention to Qatar’s position in the development of stem cell research in the region and the world, given that research on stem cell … Continue reading →

Stem cell find offers hope for infertility By Lauran Neergard Monday, February 27, 2012 An experiment that produced human eggs from stem cells could one day be a boon for women who are desperate to have a baby, according to a study published yesterday. The work sweeps away the belief that a woman has only a limited stock of eggs and replaces it with the theory that the supply is continuously replenished from precursor cells in the ovary, its authors said. If the report is confirmed, harnessing those stem cells might one day lead to better treatments for women left infertile because of disease — or simply because they’re getting older. "Our current views of ovarian aging are incomplete. There’s much more to the story than simply the trickling away of a fixed pool of eggs," said lead researcher Jonathan Tilly of Harvard’s Massachusetts General Hospital, who had long hunted these cells in a series of studies. His previous work drew fierce scepticism. Independent experts urged caution about the latest findings. A key next step is to see whether other laboratories can verify the work. If so, then it would take years of additional research to learn how to use … Continue reading →

By Carolyn Y. Johnson, Globe Staff Massachusetts General Hospital researchers reported today they have discovered a rare stem cell in women’s ovaries that they hope one day might be used to make eggs, a claim already generating vigorous debate among scientists familiar with the research. For decades, it has been thought that women are born with a finite supply of eggs, limiting their reproductive years. Doctors have sought ways of extending the fertility of women, especially as many wait later in life to begin having children. The research, led by Jonathan Tilly of Mass. General and appearing in the journal Nature Medicine, opens the door to the possibility of taking tissue from a woman’s ovaries, harvesting stem cells from that tissue, and then creating eggs. But scientists not involved with the Mass. General research said such an approach -- if it is even possible -- sits far in the future and will require considerably more work. Several scientists said Tilly, who co-founded a company focused on developing novel infertility treatments, had not yet made a convincing case that the stem cells he discovered can yield viable eggs, a critical first step. Tilly has been a lightning rod in the field … Continue reading →

The word or acronym "AIDS" is one of the most complex, confusing and mysterious words in science, medicine and in the English language. It's impossible for a medical dictionary to accurately define it. No matter what anyone says, "AIDS" is not clear cut. Its four letters which make up the acronym are centered in a web of complexity, so much so it took 58-minutes, just to scratch the surface. In this clip we look at: 1) CDC: Initial AIDS Definition 2) Clinical AIDS: A New Disease 3) A Growing Family: AIDS Marker Diseases and Indicators [opportunistic Infections?] or "old and familiar " Original Infections? 4) Creating an African AIDS Definition Bangui: AIDS By Numbers 5) Bangui: Peripheral Psychological Damage 6) Bangui Redux: National Variations in AIDS Definitions 7)Through a Glass Darkly: African AIDS Statistics Bangui Westernized 8) Politics and Public Health: A Study in Conflict 9) CD4 T-Cell Count Marker: Medical Application 10) Addition by Subtraction: 1997 CDC Tables 11 and 12 Visit http://www.houseofnumbers.com for more information Go here to see the original: AIDS - a syndrome or clever … Continue reading →
