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 ...

The art of building bone

Cell differentiation is a widely studied phenomenon forming the basis of all developmental processes including fetal growth and bone fracture healing. A series of recent studies indicates the emerging role of chondrocyte-to-osteoblast ...

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 ...

Can inhaled stem cells fix your brain?

(Medical Xpress)—In certain neurosurgical procedures, like fixing pituitary glands, surgeons can remove a tumor through the nose with minimal damage to surrounding tissue. It turns out, that passing things in the other ...

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 ...

Heart attack damage reduced by shielded stem cells

Bioengineers and surgeons from Rice University and Baylor College of Medicine (BCM) have shown that shielding stem cells with a novel biomaterial improves the cells' ability to heal heart injuries caused by heart attacks.
