干细胞被认为是化学致癌物的必要靶点。基于放射自显影,超微结构和生物学标准,我们最近提出,毛囊干细胞不居住在球,但在上部外根鞘的一个地区称为隆起。增殖细胞已被证明更容易发生肿瘤,我们最近证明隆突中的细胞在生长初期会经历短暂的增殖。因此,我们推测小鼠皮肤在生长初期阶段特别容易受到致癌物的影响。在本文中,我们表明,早期生长期瑞士和森卡尔小鼠皮肤确实是特别容易受到一个和两个阶段的化学致癌作用,导致肿瘤产量的1至5倍,与休止期定时致癌物的应用。我们的研究结果表明,隆突细胞可能参与了一些皮肤癌的前体,并支持了这些细胞是干细胞的概念。这些观察结果也提出了重要的问题,化学诱导的小鼠皮肤肿瘤的细胞起源和生物学行为。
Stem cells are believed to be a necessary target of chemical carginogens. Based on autoradiographic, ultrastructural, and biologic criteria, we have recently proposed that hair follicle stem cells reside not in the bulb, but in the upper outer root sheath in an area called the bulge. Proliferating cells have been shown to be more susceptible to tumor initiation, and we have recently demonstrated that cells in the bulge undergo transient proliferation during early anagen. Therefore, we theorized that mouse skin should be particularly susceptible to carcinogen application during early anagen phase. In this paper, we show that early anagen Swiss and Sencar mouse skin is indeed particularly susceptible to one- and two-stage chemical carcinogenesis, resulting in tumor yields one to five times those obtained with telogen-timed carcinogen application. Our findings implicate a possible involvement of the bulge cells as precursors to some of the skin cancers, and support the concept that these are stem cells. These observations also raise important questions about the cellular origins and biologic behavior of chemically induced murine skin tumors.
