3D Bioprinting Skin Pigmentation
3D bioprinted skin is used in multiple applications including skin grafts, toxicology, and chemical testing. Traditional techniques creates a product that lacks the complexities of real skin such as pigmentation, pore size variation, and hair follicles. Researchers at A*STAR's Singapore Institute of Manufacturing Technology (SIMTech) and the Singapore Centre for 3D Printing (SC3DP) are aiming to change that. Using 3D bioprinting and three types of skin cells, they are able to control the distribution of melanocytes across constructed tissue, replicating human skin pigmentation. This technique not only creates uniform pigmentation, but also allows them to control pore size, paving the way for the printed skin to be used in toxicology and cell biology research.
