Rescue services at the cellular level: How stem cells help brain to regain its functions after stroke

(PhysOrg.com) -- The aim of regenerative medicine is to repair or replace malfunctioning cells, tissues, and even organs. Stem cells, the multi-taskers and jacks-of-all-trades that can regenerate themselves indefinitely and transform themselves into various cell types, are seen as offering a promising solution in this context. Researchers have reported numerous cases of the successful use of stem cells to heal damaged tissue; however, the underlying physiological mechanisms at work here are still largely unknown.
