Abstract

The progress in reconstruction of an in vitro three-dimensional skin model that accurately represents the complex human skin microenvironment depends on the advance of tissue engineering. In this way, the 3D bioprinting technique is an emerging technology that allows the precise, hierarchical and automated deposition of cells and biomaterials for the construction of mimetics with greater structural complexity, reproducibility and speed. Thus, bioprinted skin models provide a platform of high relevance for studies of skin pathophysiology, as well as supplying the need for a system to evaluate the safety and efficacy of cosmetics and medicines alternative to the animals use. Studies with bioprinted skins containing cell types beyond the classical combination of keratinocytes and fibroblasts, representing the dermal and epidermal layers are still limited, demonstrating that this is a field that is at the frontier of knowledge and represents a major technological challenge. Therefore, the objective of this research project is the reconstruction of a three-dimensional skin, containing in addition to the dermis and epidermal layers, the layer of hypodermis and all its fundamental cell types, using 3D bioprinting technology.
