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。

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；
