Mini Stem-Cell Labs
April 2, 2008
Stem-cell therapies are often touted as the future of tissue engineering and regenerative medicine. But one of the challenges to developing such therapies is creating an environment in which stem cells can grow. An additional hurdle involves designing a vehicle to deliver stem cells to their target, without being detected by the body’s immune system. Now scientists at Northwestern University have engineered a “miniature laboratory” in the form of a tiny, gel-like sac. They successfully grew stem cells within the sac, delivering proteins and nutrients to the cells through the sac’s membrane. (Technology Review)
