Regenerative medicine

Gelatin-hydrogel wrapped skin organoids promote wound healing in frostbite-affected skin.

Healing Frostbite Without Scars: The Promise of Skin Organoids

The conditions for 3D bioprinting of adipose tissues involved the use of adipose-derived decellularized extracellular matrix and alginate as a hybrid ink. The optimal diameter of adipose units and the spacing between them were established. In addition to promoting wound healing in vitro, the bioprinted adipose tissue promoted skin regeneration in a mouse skin wound model by regulating cell migration, vasculogenesis, and keratinocyte differentiation.

3D Fat Printing Supercharges Wound Healing

The new tissue engineering method uses a bioink derived from Kombucha SCOBY nanocellulose, reinforced with chitosan and kaolin, and a handheld biopen. The digitally controlled biopen enables precise and personalized wound repair or 3D bioprinting of complex structures.

Astrocytes Reprogrammed into Brain Stem Cells: A New Hope for Regenerative Medicine

Photograph of a common European starfish (Asterias rubens) with a regenerating arm. Starfish can shed their arms (a process called autotomy) when attacked by predators and later regenerate the lost arm. Researchers at Queen Mary University of London have discovered the mechanisms behind autotomy, identifying a neurohormone that triggers arm loss in starfish.

Scientists identify ‘missing piece’ required for blood stem cell self-renewal

Inhibition of an ESI1 target promotes oligodendrocyte myelin production in mice, as shown as a dense curtain of green strands. This small molecule shows early promise as a potential treatment for MS, and to manage aging-related nerve sheath deterioration, according to study led by experts at Cincinnati Children's.
