摘要: 本研究旨在探讨羊驼皮肤黑素细胞的分离、培养及鉴定方法,为进一步研究色素沉积提供合适的细胞模型。取1~3岁的青年羊驼皮肤,用胰酶、胰酶∶EDTA、DispaseⅡ酶3种不同的消化酶消化羊驼皮肤,再用胰酶∶EDTA消化,分离得到羊驼黑素细胞,接种于多种促进黑素细胞生长的营养成分DMEM/F12培养基中,通过观察黑素细胞的生长、细胞接种数和细胞贴壁数检验黑素细胞的纯度。结果表明,DispaseⅡ组处理的羊驼皮肤,分离得到的黑素细胞明显多于其它2个组(P<0.01)。综上所述,选用DispaseⅡ酶作为分离羊驼皮肤的消化酶,可获得较纯的黑素细胞。

Abstract: In order to explore and establish a new method of isolation,culture,and identification of alpaca skin melanocyte in vitro for further studying to provide a suitable pigment deposition cell model. Take 1 to 3 years young alpacal skin,with three different enzymes (trypsin,trypsin-EDTA,Dispase Ⅱ) digestion alpaca skin,alpaca melanocyte were obtained by trypsin-EDTA digestion,placed into DMEM/F12 culture medium. Analyze melanocyte growth,cell yields and cells attached.The results showed Dispase Ⅱ group had a significant higher other groups (P<0.01).In summary,alpaca melanocyte were obtained by Dispase Ⅱ digestion.

Key words: alpaca; melanocyte; DispaseⅡ; depuration
