X-Message-Number: 32328 From: David Stodolsky <> Subject: Regenerating Blood Vessels Date: Thu, 21 Jan 2010 17:07:26 +0100 http://www.hhmi.org/news/rafii20100117.html Howard Hughes Medical Institute (HHMI) researchers have devised a new method that increases the number of blood vessel-forming cells they can make from human embryonic stem cells. The advance could improve the odds for successful cell-based therapies to treat heart disease or stroke, and might also aid engineering of artificial organs. Eventually, Rafii wants to inject the vascular endothelial cells into the hearts of patients with late-stage heart failure and see if the cells boost the heart's function. It could take three to four years to get there, he says, but with the current study, "we've taken the first major step to get to that stage.” The impact could extend beyond heart disease, as well. Patients with many conditions, such as stroke, clogged vessels in the lower limbs, or diabetes, could benefit from repairing blood vessels. And engineering organs requires blood vessels too, so Rafii's method of making blood vessel cells could aid efforts to construct organs in culture. dss David Stodolsky Skype: davidstodolsky Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=32328
