Research shows that cells from older people have impaired mitochondria, reducing energy production. The findings could open the door to discovering a clear link between mitochondrial dysfunction and age related neurodegeneration.
The first human corneas have been 3D printed by scientists. The technique could be used in the future to ensure an unlimited supply of corneas. The proof-of-concept research showed how stem cells from a healthy donor cornea were mixed together with alginate and collagen to create a ‘bio-ink’..
