背景:富血小板血浆含有多种刺激因子,且能上调蛋白多糖及胶原合成。目的:观察山羊富血小板血浆对山羊骨髓间充质干细胞增殖的影响。方法:抽取6月龄的内蒙古锡盟山羊颈静脉血,采用二度离心法获取富血小板血浆,运用骨髓穿刺包从山羊髂骨上抽取骨髓,采用密度梯度离心方法分离、纯化获得山羊骨髓间充质干细胞,然后取生长状态较好的原代细胞,加入含体积分数为10%,20%,30%富血小板血浆的 L-DMEM 完全培养基进行培养,对照组只用L-DMEM完全培养基培养。结果与结论:在2-6d期间,富血小板血浆各组明显比对照组细胞增殖迅速,而且体积分数越高细胞生长的速度越快,生长的数目越多,细胞形态越成熟。培养第4天时,体积分数为10%,20%,30%富血小板血浆组细胞倍增时间约为50 h,35 h,25 h。结果表明山羊富血小板血浆能明显促进骨髓间充质干细胞的增殖,而且富血小板血浆体积分数越大促增殖能力越显著。
揹景:富血小闆血漿含有多種刺激因子,且能上調蛋白多糖及膠原閤成。目的:觀察山羊富血小闆血漿對山羊骨髓間充質榦細胞增殖的影響。方法:抽取6月齡的內矇古錫盟山羊頸靜脈血,採用二度離心法穫取富血小闆血漿,運用骨髓穿刺包從山羊髂骨上抽取骨髓,採用密度梯度離心方法分離、純化穫得山羊骨髓間充質榦細胞,然後取生長狀態較好的原代細胞,加入含體積分數為10%,20%,30%富血小闆血漿的 L-DMEM 完全培養基進行培養,對照組隻用L-DMEM完全培養基培養。結果與結論:在2-6d期間,富血小闆血漿各組明顯比對照組細胞增殖迅速,而且體積分數越高細胞生長的速度越快,生長的數目越多,細胞形態越成熟。培養第4天時,體積分數為10%,20%,30%富血小闆血漿組細胞倍增時間約為50 h,35 h,25 h。結果錶明山羊富血小闆血漿能明顯促進骨髓間充質榦細胞的增殖,而且富血小闆血漿體積分數越大促增殖能力越顯著。

BACKGROUND:Platelet-rich plasma contains a variety of stimulating factors, and can also raise the proteoglycan and col agen synthesis. OBJECTIVE:To observe the effect of platelet-rich plasma on the proliferation of goat bone marrow mesenchymal stem cel s. METHODS:Blood samples were extracted from the jugular vein of Inner Mongolia Ximeng goats to harvest platelet-rich plasma using centrifugation method. Then, bone marrow was extracted from the goat’s ilium by puncture method to isolate and purify goat bone marrow mesechymal stem cel s using density gradient centrifugation method. After that, primary cel s at good state were cultured in L-DMEM complete medium containing 10%, 20%, 30%platelet-rich plasma or in simple L-DMEM complete medium. RESULTS AND CONCLUSION:Within 2-6 days of culture, cel s in the platelet-rich plasma groups proliferated faster than those in the control group, and with the increasing of platelet-rich plasma concentration, the cel s grew faster, with larger number and more mature morphology. At 4 days of culture, the cel doubling time was about 50, 35, 25 hours in the 10%, 20%, and 30%platelet-rich plasma groups, respectively. These findings indicate that goat platelet-rich plasma can dramatical y promote the proliferation of bone marrow mesenchymal stem cel s in a concentration-dependent manner.
