Abstract

Severe burns are often treated by means of autologous skin grafts, preferably following early excision of the burnt tissue. In the case of, for example, a large surface trauma, autologous skin cells can be expanded in vitro prior to transplantation to facilitate the treatment when insufficient uninjured skin is a limitation. In this study we have analyzed the impact of the enzyme (trypsin or accutase) used for cell dissociation and the incubation time on cell viability and expansion potential, as well as expression of cell surface markers indicative of stemness. Skin was collected from five individuals undergoing abdominal reduction surgery and the epidermal compartment was digested in either trypsin or accutase. Trypsin generally generated more cells than accutase and with higher viability; however, after 7 days of subsequent culture, accutase-digested samples tended to have a higher cell count than trypsin, although the differences were not significant. No significant difference was found between the enzymes in median fluorescence intensity of the analyzed stem cell markers; however, accutase digestion generated significantly higher levels of CD117- and CD49f-positive cells, but only in the 5 h digestion group. In conclusion, digestion time appeared to affect the isolated cells more than the choice of enzyme.

摘要

严重烧伤通常通过自体皮片移植来治疗,最好在早期切除烧伤组织后进行。例如,对于大面积的创伤,可以在移植前体外扩增自体皮肤细胞,以解决当供皮区不足时的治疗难题。在这项研究中,我们分析了用于细胞解离的酶(胰蛋白酶或胶原酶)和孵育时间对细胞活力和扩增潜能的影响,以及对干性标志物的表达。从接受腹部整形手术的五名个体中采集皮肤,将表皮部分用胰蛋白酶或胶原酶消化。胰蛋白酶通常比胶原酶产生更多的细胞,且活力更高;然而,在随后的 7 天培养后,与胰蛋白酶相比,胶原酶消化的样本倾向于具有更高的细胞计数,尽管差异不显著。两种酶在分析的干细胞标志物的中值荧光强度上没有发现显著差异;然而,胶原酶消化产生的 CD117 和 CD49f 阳性细胞水平显著更高,但仅在 5 小时消化组中如此。总之,消化时间似乎比酶的选择对分离的细胞影响更大。
