我们使用人类原发性前列腺上皮细胞,报告一种新的无生物标记方法,通过基于球体的标签保留测定,对干细胞进行功能表征。介绍了 BrdU、CFSE 或远红色 2D 细胞标记的分步协议;三维球形形成;通过免疫细胞化学进行标签保留干细胞鉴定;和隔离由FACS。

干细胞分离仍然是一个主要的挑战,因为使用当前方法共同隔离祖先细胞。我们开发了一种新型无生物标志物的检测方法,从混合祖体中分离出静态干细胞。这种基于球形的标签保留分析的主要优点是,它可以利用CFSE或远红标签,通过FACS从其子祖先中扩展和分离活干细胞。

虽然传统疗法可以根除大多数前列腺癌细胞,但癌症干细胞仍然由于治疗阻力而存在,从而推动疾病进展。干细胞样细胞分离将允许识别新的基因,这些基因可以在治疗上共同定位,以有效缓解疾病。我们的标签保留测定适用于从各种组织和细胞中分离的正常干细胞,以及癌症干细胞研究。
