In order to investigate the possible re-epithelialization originated from the dermal epithelial components after trypsinization of the allo-dermis, microscopic observation, tissue culture study and histological observation after allo-grafting were adopted. The number of the hair follicles in dermal layer was counted in the study process. The results showed that a few of hair follicles in the structure of allo-dermis remained after trypsin digestion for 80 minutes. After culturing and grafting of such trypsinized dermis, none of the newly formed epithelium was observed.
为了研究同种异体真皮胰蛋白酶消化后源自真皮上皮成分的可能的再上皮化情况，采用了显微镜观察、组织培养研究以及同种异体移植后的组织学观察。在研究过程中对真皮层毛囊数量进行了计数。结果显示，胰蛋白酶消化80分钟后，同种异体真皮结构中的少数毛囊得以保留。对这种经胰蛋白酶处理的真皮进行培养和移植后，未观察到新形成的上皮。
