ScienceDaily (July 18, 2012) — New research at the Hebrew University of Jerusalem sheds light on pluripotency -- the ability of embryonic stem cells to renew themselves indefinitely and to differentiate into all types of mature cells. Solving this problem, which is a major challenge in modern biology, could expedite the use of embryonic stem cells in cell therapy and regenerative medicine.

If scientists can replicate the mechanisms that make pluripotency possible, they could create cells in the laboratory which could be implanted in humans to cure diseases characterized by cell death, such as Alzheimer's, Parkinson's, diabetes and other degenerative diseases.

To shed light on these processes, researchers in the lab of Dr. Eran Meshorer, in the Department of Genetics at the Hebrew University's Alexander Silberman Institute of Life Sciences, are combining molecular, microscopic and genomic approaches. Meshorer's team is focusing on epigenetic pathways -- which cause biological changes without a corresponding change in the DNA sequence -- that are specific to embryonic stem cells
