Objective To explore the role of ADSCs and PRP in soft tissue defect repairing .Methods Harvest adipose tissue from inguinalis fat pad of SD rats ,isolation ,culture ,and identification the ADSCs through three differentiation method .Take 30 male SD rats about 6-7 weeks old randomly .Randomly selected 12 rats been take blood from heart .Preparation the PRP with modi-fied appel method .To count platelet of whole blood and PRP under microscope .Take the remaining rats .Divided the rat into 3 groups(n=6 in each group) randomly ,of which group A treatment with ADSCs and PRP ;Group B treatment with ADSCs ;Group C treatment whit PRP .Selected one side of skin defect wound for test randomly and the relative side skin defect is for control ,Handle all of the control wound to group D ;Observe the grow th of granulation tissue on the wound surface ;observe the inflammatory sur-rounding and the degree about epithelial .statistical analysis and record the wound size ,and calculation the shrinkage rate of wound in different periods .Record the time of completely healing time .Histologic observation of the wound healing tissue .Results Plate-let counting showed platelet of PRP is 5 .21 times than whole blood .The wound completely healed time :group A (18 .25 ± 1 .44 ) days ,group B(19 .13 ± 1 .28)days ,group C(19 .72 ± 0 .87)days ,group D(22 .31 ± 1 .65) days ,The time of each treatment group and control group was significantly obvious(P< 0 .05) .At 3 ,7 ,11 and 15 days after experimental treatment ,compared with the control group the experiment group of wound contraction rate was significantly obvious (P<0 .05) .Conclusion Application of AD-SCs with PRP can enhance the quality and shorten the wound healing time than used them alone .%目的：探讨富血小板血浆（PRP）凝胶和脂肪干细胞（ADSCs）在创面修复中的作用。方法取大鼠腹股沟脂肪组织，使用贴壁筛选法分离、培养ADSCs ，三系诱导分化鉴定。取6～7周龄雄性SD大鼠30只，随机选取12只大鼠经心脏取动脉血7～10 mL/只，采用改良Appel法制备PRP ；倒置相差显微镜下对留存的全血及PRP进行血小板计数。剩余18只大鼠随机分成3组，每组6只；A组为ADSCs＋PRP处理组，B组为ADSCs处理组；C组为PRP处理组，所有未处理创面设定为D组（对照组）；观察创面肉芽组织生长情况，创面周围炎症反应及上皮化程度。记录创伤后各时间点创面面积、创面收缩率、创面完全愈合时间；24 d后处死各组大鼠，取创面愈合组织，HE染色观察。结果大鼠PRP中血小板计数约为全血的5．21倍。创面完全愈合所需要的时间A组为（18．25±1．44）d ，B组为（19．13±1．28）d ，C组为（19．72±0．87）d ，D组为（22．31±1．65）d；术后3、7、11、15 d A、B、C组创面收缩率均高于D组（P＜0．05）。结论 PRP凝胶可促进ADSCs修复创面，且较单独使用ADSCs或PRP效果好。
