Bone Marrow Donation Saves Lives

Cheryl Phillips — Sun, 15 Nov 2009 21:56:34 -0600

In the US alone, 6,000 people need a bone marrow transplant on any given day. Offering to donate bone marrow can save lives threatened by cancers and blood diseases. Donating bone marrow is commonly done as a surgical procedure and often requires anesthesia, but saving lives with the donation is an incredible gift to others.

Liver fibrosis occurs in the setting of chronic injury caused by different etiologies constituting a serious worldwide public health problem. In addition to schistosomiasis, hepatopathies due to alcohol, viral hepatitis, drugs, metabolic and autoimmune diseases, and congenital abnormalities are important causes of liver fibrosis.

New studies in the laboratory of Dr. Darwin J. Prockop, Director of Tulane University's Center for Gene Therapy, are shedding light on the previously mysterious mechanism through which even relatively small amounts of stem/progenitor cells taken from a patient's own bone marrow enhance repair of damaged tissues.
