7、病傳播或免疫排斥的可能性、且移植物無法準(zhǔn)確塑形替代原組織的生物力學(xué)特性。如何實(shí)現(xiàn)骨缺損修復(fù)重建一直是當(dāng)今醫(yī)學(xué)界的難題，組織工程支架為解決這一難題提供了很好的思路。本實(shí)驗(yàn)旨在采用冷凍干燥法制備膠原蛋白/殼聚糖/羥基磷灰石三維仿生骨組織工程支架，并觀察膠原蛋白/殼聚糖/羥基磷灰石三維復(fù)合支架對(duì)骨髓間充質(zhì)干細(xì)胞的增殖和分化的影響。目的是研究組織工程支架治療骨缺損修復(fù)重建的可行性。方法：1.大鼠骨髓間充質(zhì)干細(xì)胞（BMSCs）的分離培養(yǎng)和分化鑒定：抽取清潔級(jí)健康雄性SD大鼠骨髓，密度梯度離心法提取單個(gè)核細(xì)胞，貼壁法分離骨髓間充質(zhì)干細(xì)胞。通過CCK-8法檢測(cè)
8、細(xì)胞生長曲線；成骨誘導(dǎo)分化培養(yǎng)后，進(jìn)行茜素紅染色檢測(cè)礦物結(jié)節(jié)染色評(píng)估成骨分化情況。2.膠原/殼聚糖/羥基磷灰石復(fù)合支架制備：采用冷凍干燥
