Abstract:
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 .
