3D-bioprinted human skin can replace animal testing, potentially be used in burns

FacebooktwitterlinkedinFacebooktwitterlinkedin

José Luis Jorcano at Universidad Carlos III de Madrid has developed a 3D bioprinter capable of replicating the structure of skin. The human-like  skin that is produced  includes an epidermal layer that protects against the environment, and a collagen-producing dermis that provides elasticity and strength.

The bioink material  contains human plasma, and  primary human fibroblasts and keratinocytes obtained from biopsies.

Currently, 100 cm2 of the printed skin  is able to be produced in 35 minutes.
