摘要:

背景:课题组前期实验发现用液氮冻融激活的改良富血小板血浆可以促进骨髓间充质干细胞和牙髓干细胞的增殖,且这种促增殖作用具有浓度特异性。
目的:体外研究不同浓度的改良富血小板血浆对人乳牙牙髓干细胞增殖的影响。
方法:利用全自动血细胞分离机制备血小板浓缩物,反复冻融法激活,获得改良富血小板血浆;以α-MEM作为基础培养基,分别加入体积分数为2%,5%,10%,20% 4种不同浓度改良富血小板血浆或者体积分数10%胎牛血清进行培养,观察细胞增殖差异。
结果与结论:不同浓度的改良富血小板血浆均能够促进乳牙牙髓干细胞增殖,体积分数2%改良富血小板血浆与体积分数10%胎牛血清促进乳牙牙髓干细胞增殖作用接近。提示体积分数2%改良富血小板血浆可以促进乳牙牙髓干细胞的增殖,有可能代替胎牛血清用于乳牙牙髓干细胞的体外扩增。

Abstract:

BACKGROUND: Previous experiments have shown that modified platelet-rich plasma activated by liquid nitrogen freezing and thawing can promote the proliferation of human bone marrow mesenchymal stem cells and dental pulp stem cells in a concentration-dependent manner.
OBJECTIVE: To investigate the effect of modified platelet-rich plasma at different concentrations on the proliferation of dental pulp stem cells from human exfoliated deciduous teeth.
METHODS: Platelets were selected and harvested by automatic blood cell analyzer, and then activated by liquid nitrogen freezing and thawing. α-MEM served as basal medium. Different concentrations of modified platelet-rich plasma (2%, 5%, 10%, 20%) or 10% fetal bovine serum were added, respectively. The difference in cell proliferation was observed.
RESULTS AND CONCLUSION: Modified platelet-rich plasma at different concentrations could promote the proliferation of dental pulp stem cells from deciduous teeth. The effects of 2% modified platelet-rich plasma and 10% fetal bovine serum on promoting the proliferation of dental pulp stem cells from deciduous teeth were similar. These results indicated that 2% modified platelet-rich plasma could promote the proliferation of dental pulp stem cells from deciduous teeth, and substitute for fetal bovine serum in the amplification of dental pulp stem cells from deciduous teeth in vitro.
