以前已经观察到单个鸡胚胎肢体间充质细胞在胶原或琼脂糖凝胶中培养时可以分化为软骨细胞,而不发生细胞间相互作用。在目前的研究中,当放置在这种胶原凝胶培养物上时,肢体外胚层,而不是真皮,会抑制软骨形成。即使外胚层被放置在多孔过滤器上,这种抑制作用也能在凝胶中传播很远的距离。用肢体外胚层预处理的胶原凝胶也能抑制软骨形成。另一方面,当间充质细胞置于琼脂糖中时,外胚层对软骨形成的抑制作用较小。这些结果表明,肢体外胚层的抗软骨作用是通过改变胶原细胞外基质介导的,并支持细胞外基质必须被视为能够调节细胞分化的有组织的功能单位的观点。
It has been previously observed that single chick embryonic limb mesenchymal cells can differentiate into chondrocytes without cell-cell interactions when cultured in collagen or agarose gels. In the present study, limb ectoderm, but not dermis, inhibits chondrogenesis when placed on such collagen gel cultures. The inhibitory influence can be transmitted extensive distances in the gel, even when the ectoderm is placed on a porous filter. Collagen gels, preconditioned with limb ectoderms, are also inhibitory to chondrogenesis. On the other hand, chondrogenesis is less inhibited by ectoderm when the mesenchymal cells are placed in agarose. These results suggest that the antichondrogenic effect of limb ectoderm is mediated through alterations of the collagenous extracellular matrix and support the idea that the extracellular matrix must be considered as an organized, functional unit capable of regulating cell differentiation.
