Embryonic stem cells can give rise to every cell type in the body. A team of researchers has now identified a cellular mechanism that is important for the ability of these cells to maintain their state as stem cells. The findings add to the knowledge needed to bring forward the […]

Tissue engineering of new cartilage is an important goal in the field of regenerative medicine, but it has proven challenging to obtain the necessary structural properties. Natural cartilage is a resilient, strong tissue. Incremental progress towards this goal has been made over the years, as researchers explored the space of […]

It is well demonstrated that structured exercise programs improve function and reduce mortality in old humans, in part because the majority of people do not undertake anywhere near enough exercise.
