Tropocollagen

The collagen fibrils of NaCl and STPP treatments disassociated more thinner tropocollagen fibrils which liked disordered silk thread and separated from each other .

NaCl和TSPP处理的样品，胶原纤维分散成更细的原胶原纤维，好像散乱的丝线，且彼此很分散。

Bone formation Hydroxyapatite is deposited in nucleation sites between the ends of tropocollagen molecules as the first step in bone formation .

骨骼形成的第一步，羧基磷灰石被沉积在原胶原蛋白分子末羰之间的成核部位。

The both ends of tropocollagen with positive charge is physical and chemical basis of fracture healing

胶原分子两端带正电是骨折愈合的理化基础

Results Much tropocollagen could be found in the extracellular matrix by transmission electron microscope when the osteoblasts were cultured with ascorbate and β - glycerophosphate .

结果成骨细胞经体外诱导培养后透射电镜下观察，细胞外基质中可见大量原胶原；
