目的 比较自体与同种异体富血小板血浆(PRP)在体外对兔骨髓基质干细胞(BMSCs)增殖、分化效应的差异,探讨同种异体PRP促BMSCs增殖与分化的最适作用浓度. 方法 选取新西兰兔3只,常规培养BMSCs,制备PRP.实验分为4组:空白组(达尔伯克改良伊格尔培养基)、常规组(在空白组基础上加10%胎牛血清)、自体组(在常规组基础上加自体PRP萃取液)与同种异体组(在常规组基础上加同种异体PRP萃取液).同种异体组又按PRP与培养液体积百分比不同依次分为10%、20%、30%、40%、50%5种浓度亚组.获得最佳PRP浓度同种异体组后,自体组预设一组相应的PRP浓度亚组.分别于干预后的第4、8、12、16、20天检测各组BMSCs的四唑盐(M TT)值及碱性磷酸酶(ALP)活性,并用促增殖与分化的最适浓度检测各组BMSCs的凋亡率,比较自体与同种异体PRP对BMSCs增殖、分化与凋亡效应的差异. 结果 PRP对BMSCs的分化效应随着增殖效应的增强而变弱,其促BMSCs增殖的最佳浓度约为30%.干预至第4、8、12、16、20天时,30%自体组和30%同种异体组PRP对BMSCs的增殖、分化效应比较差异均无统计学意义(P>0.05).干预第20天时,空白组、常规组、30%自体组及30%同种异体组BMSCs凋亡率平均分别为38.7%±2.0%、24.1%±1.7%、9.7%±0.8%、10.3%±1.2%,30%自体组与30%同种异体组比较差异无统计学意义(P>0.05).结论 在体外实验中,干预至相同时间30%自体组与30%同种异体组对BMSCs的增殖与分化效应无明显差异,同种异体PRP可以取代自体PRP,其促BMSCs增殖与分化的最适PRP浓度约为30%.
目的 比較自體與同種異體富血小闆血漿(PRP)在體外對兔骨髓基質榦細胞(BMSCs)增殖、分化效應的差異,探討同種異體PRP促BMSCs增殖與分化的最適作用濃度. 方法 選取新西蘭兔3隻,常規培養BMSCs,製備PRP.實驗分為4組:空白組(達爾伯剋改良伊格爾培養基)、常規組(在空白組基礎上加10%胎牛血清)、自體組(在常規組基礎上加自體PRP萃取液)與同種異體組(在常規組基礎上加同種異體PRP萃取液).同種異體組又按PRP與培養液體積百分比不同依次分為10%、20%、30%、40%、50%5種濃度亞組.穫得最佳PRP濃度同種異體組後,自體組預設一組相應的PRP濃度亞組.分彆于榦預後的第4、8、12、16、20天檢測各組BMSCs的四唑鹽(M TT)值及堿性燐痠酶(ALP)活性,併用促增殖與分化的最適濃度檢測各組BMSCs的凋亡率,比較自體與同種異體PRP對BMSCs增殖、分化與凋亡效應的差異. 結果 PRP對BMSCs的分化效應隨著增殖效應的增彊而變弱,其促BMSCs增殖的最佳濃度約為30%.榦預至第4、8、12、16、20天時,30%自體組和30%同種異體組PRP對BMSCs的增殖、分化效應比較差異均無統計學意義(P>0.05).榦預第20天時,空白組、常規組、30%自體組及30%同種異體組BMSCs凋亡率平均分彆為38.7%±2.0%、24.1%±1.7%、9.7%±0.8%、10.3%±1.2%,30%自體組與30%同種異體組比較差異無統計學意義(P>0.05).結論 在體外實驗中,榦預至相同時間30%自體組與30%同種異體組對BMSCs的增殖與分化效應無明顯差異,同種異體PRP可以取代自體PRP,其促BMSCs增殖與分化的最適PRP濃度約為30%.

Objective To investigate whether autologous platelet-rich plasma (PRP) can be replaced by allogeneic PRP to promote the in vitro proliferation and differentiation of bone marrow stromal stem cells (BMSCs) in rabbits and to find an optimal concentration at which allogeneic PRP can best promote the proliferation and differentiation of BMSCs.Methods Three New Zealand rabbits were used for conventional culture of BMSCs and preparation of PRP.Experiments were conducted in 4 groups with 4 kinds of culture medium:blank group (DMEM only),conventional group [DMEM containing 10% fetal bovine serum (FBS)],autologous group (DMEM containing 10% FBS plus autologous PRP extract) and allogeneic group (DMEM containing 10% FBS plus allogeneic PRP extract).The allogeneic group was further divided into five subgroups according to the concentrations of PRP extract in the medium:10%,20%,30%,40% and 50% respectively.After the best concentration was determined in the allogeneic group,it was used in the autologous group to compare the effects of the 2 kinds of PRP.On day 4,8,12,16 and 20 after intervention,optical density (OD) value in MTT assay and alkaline phosphatase (ALP) activity were tested in all groups and the cell apoptosis rate at the best concentration of PRP extract was also assessed in each group.Results The effect of PRP on the proliferation and differentiation of BMSCs was negatively related to the concentration of PRP.The optimal concentration of PRP for promotion of the proliferation of BMSCs was 30%.There was no significant difference between the autologous and allogeneic PRP (30%) regarding their effects on proliferation and differentiation of BMSCs on day 4,8,12,16 or 20 (P > 0.05).On day 20,the cell apoptosis rates in blank group,conventional group,autologous group (30%) and allogeneic group (30%)were respectively 38.7% ± 2.0%,24.1% ± 1.7%,9.7% ±0.8% and 10.3 ± l.2%,with no significant difference between autologous and allogeneic groups (P > 0.05).Conclusions Autologous PRP could be replaced by allogeneic PRP in vitro culture of BMSCs; the optimal concentration of PRP for promotion of the proliferation of BMSCs is about 30%.
