A group of scientists in Spain has created a 3D bioprinter that can 3D print functional human skin, one of the first living human organs created with bioprinting.
The bioprinted skin mimics the structure of human skin. It has an external layer—the epidermis with its stratum corneum—that protects against environmental factors and a thicker, deeper layer—the dermis—that gives the bioprinted skin its elasticity and mechanical strength.
Bioprinting skin is used to make allogeneic skin on a large scale for industrial purposes and from a stock of cells. It is also used to make autologous skin for therapy from a patient’s own cells. This in-vitro engineered development allows the skin to be used as grafts for skin replacement or to establish in-vitro human skin models.
