大量培养贴壁依赖性哺乳动物细胞的现代方法始于微载体技术的出现。主要是由于其制备方式和易于培养的原因,150-230微米的微珠已经被压倒性地采用,并且围绕它们的技术得到了发展。为了满足高生物量,已经开发了大孔微珠。此外,微支持物的化学性质已被调整,以便为脆弱细胞提供更好的机械磨损保护,同时将其分化重新定向到所寻求的目标(细胞因子、酶等的产生)。未来的进展取决于这项新技术固有问题的解决方案(维持稳定的增长条件等.)以及通常由动物细胞培养引起的要求(生物传感器、生物反应器的设计等)。除了这样的技术实现之外,生物学也期望从微载体在如大量制备间相染色体、毒性测试、细胞移植后的器官重建等不同领域的出现中受益。
Modern methods for the mass cultivation of anchorage-dependent mammalian cells started with the advent of microcarrier technology. Largely for reasons pertaining to their mode of preparation and ease of cultivation, 150-230 microns microbeads have been overwhelmingly adopted and the technology around them developed. To meet high biomass, macroporous microbeads have been developed. Also, the chemistry of the microsupport has been adapted in order to afford better protection of fragile cells to mechanical wear while simultaneously reorienting their differentiation towards the sought aims (production of cytokines, enzymes etc. ...). Future progress depends upon solutions being brought to problems inherent to this new technology (maintenance of steady state conditions of growth etc. ...) as well as to requirements arising from animal cell culture in general (biosensors, bioreactor's design etc. ...). Besides such technical implementations, biology at large is also expected to benefit from the advent of microcarriers in fields as diverse as the preparation of metaphasic chromosomes in bulk, toxicity testing, organ reconstitution following cell transplantation etc.
