3-D bioPen: A hydrogel injection to regenerate cartilage

Highly specialized cartilage is characteristically avascular and non-neural in composition with low cell numbers in an aliphatic environment. Despite its apparent simplicity, bioengineering regenerative hyaline cartilage ...

3-D bioprinting constructs for cartilage regeneration

Cartilage injury is a common cause of joint dysfunction and existing joint prostheses cannot remodel with host joint tissue. However, it is challenging to develop large-scale biomimetic anisotropic constructs that structurally ...

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 ...

To repair a damaged heart, three cells are better than one

Cell therapy for cardiac regeneration, while promising, has been hampered by issues with long-term survival of the transplanted cells. Now, a technique that combines three different types of cells in a 3-D cluster could improve ...
