本文报道了一种分离成年公牛附睾尾上皮细胞的简便、快速方法,用1 mg/ml胶原酶的无钙、无镁Hank平衡盐溶液灌注附睾尾管腔,37 ℃孵育90分钟,可将主细胞和基底细胞释放到管腔内。在孵育结束时,可以冲洗出几个没有基质或平滑肌细胞污染的单个上皮细胞和细胞聚集体。将分离的上皮细胞悬浮在含有10%马血清的Dulbecco培养基中,在接种细胞后3小时内附着在塑料培养皿上,并在约8-12天内增殖形成单层。电镜观察和免疫组化染色结果表明,培养的上皮细胞为主细胞。公牛完整附睾尾的基底细胞在其细胞质内显示出不同数量的“脂质样”物质的存在,这些物质通常与膜的螺旋密切相关。
A simple and rapid method has been described to isolate the epithelial cells of cauda epididymidis of adult bull. Perfusion of the lumen of the cauda epididymidis with 1 mg/ml collagenase in calcium- and magnesium-free Hank’s balanced salt solution and incubation of the tissue at 37°C for 90 min releases the principal and basal cells into the lumen. Several individual epithelial cells and cell aggregates without the contamination of stromal or smooth muscle cells can be flushed out at the end of incubation. The isolated epithelial cells, suspended in Dulbecco’s medium with 10% horse serum, attach to plastic dishes within 3 h after seeding the cells and proliferate to form a monolayer in approximately 8–12 days. The electron microscopic study and immunostaining of the cultured epithelial cells indicate that the cultured cells are principal cells. The basal cells of the intact cauda epididymidis of bull show within their cytoplasm the presence of varying amounts of “lipid-like” material often closely associated with whorls of membrane.
