Summary:
Dialogue, not a monologue, is the basis of all good communication. Stem cells are no exception. Recent University of Washington (UW) research has found an early indication of two-way cellular communication. This two-way cell-to-cell signaling occurs in the miniscule niches of the body where the futures of stem cells are determined. Stem cells require these niches - nest-like microenvironments made up of regulatory cells -- in order to self-renew. Stem cells can divide and turn into many types of new cells. The niches help regulate the amount and kinds of new cells produced to meet current demands.
Commentary: Maybe this new understanding of the process of cellular renewal will provide researchers with new strategies and applications to use stem cells to treat diseases, injuries and medical coditions.
