The new therapy could prevent or limit amputations for a condition that affects more than 27 million people and is a manifestation of advanced peripheral arterial disease.

Driven by the need to develop more effective therapies requiring less recovery time for common joint conditions such as osteoarthritis, an international team including NIBIB-funded researchers has developed an integrated two-part scaffold for implantation into damaged joints -- with cartilage scaffold made from silk, and bone scaffold made from ceramics. This combination of materials allows stem cells to successfully populate the graft and differentiate into cartilage and bone cells. The cells fill the damaged areas to reconstitute the original structure of the joint, after which the scaffold biodegrades, leaving the smooth surface required for a pain-free, functioning interface.

One of the longstanding debates in science, that has, perhaps unsurprisingly, permeated into the field of stem cell research, is the question of nature versus nurture influencing development. Science on stem cells thus far, has suggested that, as one side of the existential debate holds: their fate is not predestined. But new research from the Neural Stem Cell Institute and Drexel University suggests that the cells’ tabula might not be as rasa as we have been led to believe.
