微载体培养系统中,种子细胞在培养皿或生物反应器内悬浮的微载体表面上生长,能够在一定时间内收获大量种子细胞,可将种子细胞-微载体复合体直接植入病损部位,而不用依靠支架系统。微载体可以为同源的单层细胞的生长扩增提供足够的空间,同时能节省大量昂贵的生长因子和培养液。利用微载体生物反应器培养系统还可以较容易的进行氧气浓度和物理化学 In the microcarrier culture system, the seed cells are grown on the surface of the microcarriers suspended in the petri dish or the bioreactor, and a large amount of seed cells can be harvested in a certain period of time, and the seed cell-microcarrier complex can be directly implanted into the lesion site, Without having to rely on the bracket system. Microcarriers can provide enough space for the growth and expansion of homologous monolayers, while saving a large amount of expensive growth factors and culture broth. The use of microcarrier bioreactor culture systems can also be easier for oxygen concentration and physical chemistry
