Co-Axial Electrospinning of PLLA Shell, Collagen Core Nanofibers for Skin Tissue Engineering

Scientists produced a bilayer structure by gelling GeIMA in between two nanofiber membranes to imitate the epidermal and dermal layers of skin. Cytocompatibility properties of nanofiber membrane and bilayer structure were characterized by mono- and coculture of keratinocytes and fibroblasts, respectively.
