Bioprinting for bone repair improved with gene therapy

Given enough time and energy, the body will heal, but when doctors or engineers intervene, the processes do not always proceed as planned because chemicals that control and facilitate the healing process are missing. Now, ...

Researchers succeed in cultivating cartilage from stem cells

Researchers have produced stable joint cartilage from adult stem cells originating from bone marrow. This was made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers ...

Using fat to help wounds heal without scars

Doctors have found a way to manipulate wounds to heal as regenerated skin rather than scar tissue. The method involves transforming the most common type of cells found in wounds into fat cells - something that was previously ...

Engineering new bone growth

MIT chemical engineers have devised a new implantable tissue scaffold coated with bone growth factors that are released slowly over a few weeks. When applied to bone injuries or defects, this coated scaffold induces the body ...

Same musicians: Brand new tune

A small ensemble of musicians can produce an infinite number of melodies, harmonies and rhythms. So too, do a handful of workhorse signaling pathways that interact to construct multiple structures that comprise the vertebrate ...
