Schematic representation of procedures for bioengineering fibrin mouse skeletal muscle (SkM). Macro‐ and microscopic images of C₂C₁₂ fibrin bioengineered muscle at (a) 0 days, (b) 3–4 days grown to confluency in 20% heat‐inactivated fetal bovine serum (hiFBS)/heat‐inactivated newborn calf serum (hiNBCS), (c) 5–6 days differentiated in heat‐inactivated horse serum (hiHS) for 48 h and (d) myotubes matured up to 14 days in 7% hiFBS/hiNBCS (10× magnification, scale bar = 50 μm, Olympus, CKX31)
