摘      要：We reported recombinant human-like type I collagen inducing growth of hydroxyapatite crystals in vitro in the form of self-assembly of nano-fibrils of mineralized collagen resembling extracellular matrix, which obey the same rules, but is superior to the collagen derived from animal tissues because the latter may carry diseases of animals and cause immunological reactions. The mineralized collagen fibrils aligned parallel to each other to form mineralized collagen fibers. Hydroxyapatite nanocrystals grew on the surface of these collagen fibrils with the c-axis of nanocrystals of HA orienting along the longitudinal axis of the fibrils.
