More Differentiation Progress

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

Learning how to reliably control the differentiation of stem cells is an important step in developing new regenerative medicine for presently untreatable injuries and age-related conditions. EurekAlert reports on new progress in obtaining neural cells from embryonic stem cells. "Scientists have long believed in the therapeutic promise of embryonic stem cells with their ability to replicate indefinitely and develop into any of the 220 different types of cells and tissues in the body. But researchers have struggled to convert blank-slate embryonic stem cells into motor neurons, says Zhang. The goal proved elusive even in simpler vertebrates such as mice, whose embryonic stem cells have been available to scientists for decades." Work is proceeding on blood stem cell differentiation too.
