Here are some stem cell stories that caught our eye this past week. Some are groundbreaking science, others are of personal interest to us, and still others are just fun.
Stem Cells vs. Drugs for Treating Deadly Cancer. When dealing with a potentially deadly form of cancer, choosing the right treatment is critical. But what if that treatment also poses risks, especially for older patients? Could advances in drug development render risky treatments, such as transplants, obsolete?
That was the focus of a pair of studies published this week in the New England Journal of Medicine, where a joint Israeli-Italian research team investigated the comparative benefits of two different treatments for a form of cancer called multiple myeloma.
Multiple myeloma attacks the body’s white blood cells. While rare, it is one of the most deadly forms of cancer—more than half of those diagnosed with the disease do not survive five years after being diagnosed. The standard form of treatment is usually a stem cell transplant, but with newer and better drugs coming on the market, could they render transplants unnecessary?
In the twin studies, the research team divided multiple myeloma patients into two groups. One received a combination of stem cell transplant and chemotherapy, while the other received a combination of drugs including melphalan, prednisone and lenalidmomide. After tracking these patients over a period of four years, the research team saw a clear advantage for those patients that had received the transplant-chemotherapy treatment combination.

Breaking Blood Cells’ Barricade. The process whereby stem cells mature into red blood cells is, unfortunately, not as fast as scientists would like. In fact, there is a naturally occurring barrier that keeps the production relatively slow. In a healthy person this is not necessarily a problem, but for someone in desperate need of red blood cells—it can prove to be very dangerous.
Luckily, scientists at the University of Wisconsin-Madison have found a way to break through this barrier by switching off two key proteins. Once firmly in the ‘off’ position, the team could boost the production of red blood cells.
These findings, published in the journal Blood, are critical in the context of disease anemia, where the patient’s red blood cell count is low. They also may lead to easier methods of stocking blood banks.

CIRM Scientist on the Front Lines of Cancer. Finally, HealthCanal has an enlightening profile of Dr. Denis Evseenko, a stem cell scientist and CIRM grantee from the University of California, Los Angeles (UCLA).
Born in Russia, the profile highlights Evseenko’s passion for studying embryonic stem cells—and their potential for curing currently incurable diseases. As he explains in the article:
“I had a noble vision to develop progressive therapies for the patient. It was a very practical vision too, because I realized how limited therapeutic opportunities could be for the basic scientist, and I had seen many great potential discoveries die out before they ever reached the clinic. Could I help to create the bridge between stem cells, research and actual therapeutics?”
Upon arriving at UCLA, Evseenko knew he wanted to focus this passion into the study of degenerative diseases and diseases related to aging, such as cancer. His bold vision of bridging the gap between basic and translational research has earned him support not only from CIRM, but also the National Institutes of Health and the US Department of Defense, among others. Says Evseenko:
“It’s my hope that we can translate the research we do and discoveries we make here to the clinic to directly impact patient care.”
