Embryonic skin cells committed at an early age
Surprising results from a new research study demonstrate that the embryonic cells destined to become skin have an intrinsically high commitment to irreversible differentiation and are not, as was previously thought, a stem cell-like population with a high potential for growth. The study reveals the specific molecular mechanisms that drive the unexpected early differentiation of mouse embryonic skin cells and raises several interesting questions about how these cells might respond to genetic or environmental insults.

Generating dopamine via cell therapy for Parkinson's disease
In Parkinson's disease, the loss of dopamine-producing cells in the midbrain causes well-characterized motor symptoms. Though embryonic stem cells could potentially be used to replace dopaminergic (DA) neurons in Parkinson's disease patients, such cell therapy options must still overcome technical obstacles before the approach is ready for the clinic. Dr. Lorenza Studer and colleagues at Memorial Sloan Kettering Cancer Center in New York developed three different mouse lines to better purify appropriate cells for transplantation. (2012-07-02)
