Newswise KANSAS CITY, MO - Hematopoietic stem cellsbone marrow-derived adult stem cells that give rise to the wide variety of specialized blood cellscome in two flavors: the reserve force sits quietly waiting to be called upon while the active arm continually proliferates spawning billions of blood cells every day. In their latest study, researchers at the Stowers Institute for Medical Research reveal a new mechanism that is critical in maintaining the delicate balance between the two. Publishing in the July 17 advance online issue of Nature, the team led by Stowers Investigator Linheng Li, Ph.D., reports that genomic imprinting, a process that specifically shuts down one of the two gene copies found in each mammalian cell, prevents the reservists from being called up prematurely. Active HSCs (hematopoietic stem cells) form the daily supply line that continually replenishes worn-out blood and immune cells while the reserve pool serves as a backup system that replaces damaged active HSCs and steps in during times of increased need, explains Li. In order to maintain a long-term strategic reserve of hematopoietic stem cells that lasts a lifetime it is very important to ensure that the back-up crew isnt mobilized all at once. Genomic imprinting provides … Continue reading →

July 17, 2013 Hematopoietic stem cells -- bone marrow-derived adult stem cells that give rise to the wide variety of specialized blood cells -- come in two flavors: the reserve force sits quietly waiting to be called upon while the active arm continually proliferates spawning billions of blood cells every day.

LA JOLLA The 2013 Stem Cell Meeting on the Mesa, San Diego's biggest meeting of stem cell science and business, takes place Oct. 14-16 in La Jolla. This symposium has grown over the years from a strictly scientific event to a major nexus of biotech science and business in regenerative medicine. It's sponsored by the Alliance for Regenerative Medicine, the California Institute for Regenerative Medicine and the Sanford Consortium for Regenerative Medicine. The meeting begins Oct. 14-15 with the business part, the third annual Regenerative Medicine Partnering Forum. Held at the Estancia La Jolla Hotel & Spa, this event is for business executives to discuss advances in regenerative medicine from a business perspective. On Oct. 16, the scene moves over to the Salk Institute for the eight annual Scientific Symposium. Here, scientists, business leaders, patient advocates and government officials will discuss the state of regenerative medicine from their perspectives. A preliminary agenda is available now; sponsors say a full agenda will be posted soon. And for more context about the meeting and its history, here's headlines and links to stories about the meeting in previous years: 2012 - Stem cell meeting takes on national, international flavor 2012 - Venter: Biofuels … Continue reading →

As scientists in California delve more deeply into stem cell research and reproductive science, it is essential that women donating their eggs for research not be exploited or put at risk. A bill on the governor's desk would do just that. On July 1, the state Senate passed AB 926, a bill sponsored by the American Society for Reproductive Medicine that "will reverse the current ban on compensation for women providing human oocytes (eggs) for research." That ban was passed almost unanimously in 2006; Sacramento got it right the first time. The new bill purports to "promote equity" for women as "research subjects." Since men can be paid for sperm to be used either for research or for assisted reproduction, supporters of AB 926 argue that prohibiting women from selling eggs for research is "unfair." The comparison is ludicrous. A sperm donor is screened for psychological and medical disorders. Once accepted, he may visit the sperm bank regularly. In some repositories he is provided a bed to relax on, erotic videos and magazines. While sperm donors are asked to abstain from sexual activities for two to five days before making a donation, the process is risk-free. Egg donation is invasive. … Continue reading →

LA JOLLA California's boosters like to compare its economic statistics to other nations. The message is that California's economy is more like a nation than a state. Larry Goldstein, director of UCSD's stem cell program, said California should apply that logic to funding of science and technology research. Since the federal government is cutting back, it's time for California to pick up the slack, Goldstein said at Monday's "Pipeline for Life" symposium. The event was held by the California Healthcare Institute Foundation at the Salk Institute, in San Diego's bioscience research hub of Torrey Pines Mesa. Larry Goldstein lays out the case for California funding its own sci-tech research, giving San Diego as an example of what can happen. I've embedded a short video clip above of Goldstein making his point, part of a much longer speech he gave outlining issues and opportunities in stem cell research. If you don't want to watch the video, the text of his remarks about California funding research are below. It's very slightly edited for clarity. * * * * * * "The population of California is 10 percent of the United States, we consume about 10 percent of the funding for research, but … Continue reading →
