软骨细胞在体外可行贴附培养及悬浮培养，贴附培养获得的细胞数量少且细胞易反分化，失去原来的生物学特性；悬浮培养获得的细胞数量多l’l，但设备复杂。我们在国内首次应用在生物体内可降解吸收、纤维状多微孔态的聚乙醇酸（PGA）作为支架进行免软骨细胞培养，观察PGA对培养 Chondrocytes in vitro feasible attachment culture and suspension culture, attached to the culture to obtain a small number of cells and cells easily reverse differentiation, loss of the original biological characteristics; the number of cells obtained by suspension culture more l’l, but the equipment is complicated. We first applied in vivo biodegradable absorption, fibrous microporous polyglycolic acid (PGA) as a scaffold for chondrocyte-free culture to observe the effect of PGA on culture
