Abstract

Bone graft generation in vitro is limited by slow nutrient-waste exchange through thick scaffolds and insufficient mechanical stimuli required for induction and differentiation of osteoprogenitor cells, often requiring the use of suitable bioreactors to circumvent these limitations. In this study, we test the suitability of a modified rotary miniPERM™ bioreactor system in inducing proliferation and osteodifferentiation of human foetal mesenchymal stem cell (hfMSC) on poly-ε-caprolactone (PCL)-tricalcium phosphate (TCP) scaffolds.

旋转式生物反应器用于间充质干细胞的生长和分化
骨移植物的体外生成受限于通过厚支架缓慢的营养废物交换和诱导和分化骨祖细胞所需的机械刺激不足,通常需要使用合适的生物反应器来绕过这些限制。在这项研究中,我们测试了改良的旋转miniPERM™生物反应器系统在聚-ε-己内酯(PCL)-磷酸三钙(TCP)支架上诱导人胎儿间充质干细胞(hfMSC)增殖和骨分化的适用性。
