摘要
以甲基泛影酸钠和聚蔗糖配制不连续的密度梯度离心液,分离纯化食管粘膜Langerhans细胞(Langerhanscel,LC),并以CD1a抗原阳性表达作为LC判断标准。结果显示:此法可将正常食管粘膜LC的浓度平均由分离前的1.2%提高至分离后的21%。提示:该法能从食管粘膜中分离出一定纯度的LC。
In Human esophageal Langerhans cells were isolated with discontinuous gradient centrifugation solution prepared with Ficall 400 and sodium metricote.The isolated LCs can be averagely enriched from 1.24% in normal esophageal epidermal before isolation to 21% in the acquired cell suspension after isolation by using this method.It is concluded that by using this method a certain degree of purity of LCs can be isolated from esophageal epidermal.
