Effect of niche components on masseter satellite cell differentiation on fibrin coatings.

ABSTRACT: In skeletal muscles, niche factors stimulate satellite cells to activate and induce muscle regeneration after injury. In vitro, matrigel is widely used for myoblast differentiation, however, is unsuitable for clinical applications. Therefore, this study aimed to analyze attachment and differentiation of satellite cells into myotubes on fibrin coatings with selected niche components. The attachment of satellite cells to fibrin alone and fibrin with niche components (laminin, collagen-IV, laminin-entactin complex [LEC]) were compared to matrigel. Only on matrigel and fibrin with LEC, Pax7-positive cells attached well. Then, LEC was selected to analyze proliferation, differentiation, and fusion indices. The proliferation index at day 1 on fibrin-LEC (22.5%, SD 9.1%) was similar to that on mat
