【摘 要】 目的 探討毛乳頭細胞對表皮干細胞與同種異體脫細胞真皮基質(zhì)構(gòu)建的組織工程皮膚血管化的影響。 方法 取門診包皮環(huán)切術(shù)患者皮膚，用于表皮細胞培養(yǎng)；取孕19、20 周引產(chǎn)胎兒頭部皮膚，用于毛乳頭細胞培養(yǎng)；患者及家屬均知情同意。以中性蛋白酶聯(lián)合胰蛋白酶消化、分離表皮細胞，Ⅳ型膠原黏附法分選表皮干細胞；以Ⅰ型膠原酶消化法分離毛乳頭，常規(guī)成纖維細胞培養(yǎng)液培養(yǎng)。以同種異體脫細胞真皮基質(zhì)為支架，在真皮基質(zhì)的真皮乳頭側(cè)種植毛乳頭細胞，基底膜側(cè)種植表皮干細胞構(gòu)建實驗組組織工程皮膚替代物；對照組組織工程皮膚替代物不種植毛乳頭細胞。取6 ～ 8 周齡BALB/C-nu 裸鼠60 只，隨機分成實驗組和對照組（n=30）；實驗動物背部制造1 cm × 1 cm 大小全層皮膚缺損模型，將兩組組織工程皮膚替代物移植修復(fù)創(chuàng)面，2 周后觀察移植皮膚成活率。術(shù)后2、4 周，取移植皮膚替代物標(biāo)本，行HE 及免疫組織化學(xué)染色，觀察移植皮膚替代物CD31 表達水平，并計算兩組標(biāo)本血管密度。 結(jié)果 Ⅳ型膠原分選后表皮細胞同時表達角蛋白19、β1 整合素，提示為表皮干細胞。由毛乳頭培養(yǎng)出的細胞表達α 平滑肌肌動蛋白，提示為毛乳頭細胞。動物移植術(shù)后2 周，實驗組移植皮膚成活率為93.3%（28/30），對照組為80.0%（24/30），比較差異有統(tǒng)計學(xué)意義（χ2=2.31，P=0.00）。HE 染色觀察示實驗組表皮層達12 層，表皮細胞體積較大；對照組表皮層達4 ～ 6 層，表皮細胞體積較小。實驗組術(shù)后2、4 周，血管密度分別為（38.56 ± 2.49）個/mm2 和（49.12 ± 2.39）個/mm2，對照組分別為（25.16 ± 3.73） 個 / mm2 和（36.26 ± 3.24） 個 / mm2，兩組比較差異均有統(tǒng)計學(xué)意義（P  lt; 0.01）。 結(jié)論 毛乳頭細胞可促進移植皮膚替代物血管形成，利于表皮層重建，提高組織工程皮膚移植成活率。
