Intracytoplasmic collagen fibres contained in elongated membrane-bound structures were observed in fibroblasts of regenerating tendon in the later stages of the repair process. The observations appear to support the hypothesis that collagen fibres of the intercellular matrix may be phagocytosed by the cells and degraded in the intracellular environment. Phagocytosis of extracellular collagen fibres probably represents an additional mechanism of collagen resorption during the later stages of remodelling of the regenerating tendon.
在修复过程后期再生肌腱的成纤维细胞中，观察到细长的膜结合结构内含有胞质内胶原纤维。这些观察结果似乎支持这样一种假说，即细胞间基质的胶原纤维可能被细胞吞噬并在细胞内环境中降解。细胞外胶原纤维的吞噬作用可能代表了再生肌腱重塑后期胶原吸收的另一种机制。
