Fabrication of Micropatterned Fish Scale Collagen Scaffold Using Soft Lithography for Oral Mucosa Tissue Engineering

Fish-derived collagen is considered a promising material for oral mucosa tissue engineering because it is free from risk of transmissible infectious diseases. We developed a novel fish scale collagen scaffold with micropatterns on which oral keratinocytes are cultured to create a tissue-engineered oral mucosa. Anisotropic and isotropic etching were used to fabricate negative patterns on the Si sub...
