Abstract

Hair follicle outer root sheath (ORS) is a putative source of stem cells with therapeutic capacity. ORS contains several multipotent stem cell populations, primarily in the distal compartment of the bulge region. However, the bulge is routinely obtained using invasive isolation methods, which require human scalp tissue ex vivo. Non-invasive sampling has been standardized by means of the plucking procedure, enabling to reproducibly obtain the mid-ORS part. The mid-ORS shows potential for giving rise to multiple stem cell populations in vitro. To demonstrate the phenotypic features of distal, middle, and proximal ORS parts, gene and protein expression profiles were studied in physically separated portions. The mid-part of the ORS showed a comparable or higher NGFR, nestin/, CD34, , , , , , , and PMEL expression on both protein and gene levels, when compared to the distal ORS part. Distinct subpopulations of cells exhibiting small and round morphology were characterized with flow cytometry as simultaneously expressing CD73/CD271, CD49f/CD105, nestin, and not CK10. Potentially, these distinct subpopulations can give rise to cultured neuroectodermal and mesenchymal stem cell populations in vitro. In conclusion, the mid part of the ORS holds the potential for yielding multiple stem cells, in particular mesenchymal stem cells.

摘要

毛囊外根鞘 (ORS) 是具有治疗能力的干细胞的潜在来源。ORS 包含几个多能干细胞群体,主要存在于隆起区域的远端隔室中。然而,隆起区域通常是通过侵入性分离方法获得的,这些方法需要离体的人类头皮组织。非侵入性采样已经通过拔毛程序标准化,能够重复获得中 ORS 部分。中 ORS 显示出在体外产生多种干细胞群体的潜力。为了证明远端、中间和近端 ORS 部分的表型特征,对物理分离的部分进行了基因和蛋白质表达谱研究。与远端 ORS 部分相比,ORS 的中部分在蛋白质和基因水平上均表现出相当或更高的 NGFR、巢蛋白/CD34、、、、、、、和 PMEL 表达。通过流式细胞术鉴定出具有小而圆形态的细胞的不同亚群,这些亚群同时表达 CD73/CD271、CD49f/CD105、巢蛋白,而不表达 CK10。这些不同的亚群有可能在体外产生培养的神经外胚层和间充质干细胞群体。总之,ORS 的中部分具有产生多种干细胞的潜力,特别是间充质干细胞。
