基底细胞癌(BCC)是刺猬驱动的肿瘤,类似于滤泡和滤泡间表皮基底角质形成细胞,因此长期以来一直被认为是由这些细胞引起的。然而,实际的细胞来源是未知的。通过对Ptch 1 +/−小鼠中X射线诱导的BCC进行细胞命运追踪,我们发现它们基本上唯一的来源是毛囊隆突的角蛋白15表达干细胞。然而,p53的条件性缺失不仅增强了隆突的基底细胞癌的发生,而且至少部分通过增强Smo表达而从滤泡间表皮产生了基底细胞癌。后一个发现与Ptch 1 +/−小鼠中耳朵和尾部缺乏可见肿瘤一致,这些部位缺乏Smo表达。
Basal cell carcinomas (BCCs) are hedgehog-driven tumors that resemble follicular and interfollicular epidermal basal keratinocytes and hence long have been thought to arise from these cells. However, the actual cell of origin is unknown. Using cell fate tracking of X-ray induced BCCs in Ptch1+/− mice, we found their essentially exclusive origin to be keratin 15-expressing stem cells of the follicular bulge. However, conditional loss of p53 not only enhanced BCC carcinogenesis from the bulge but also produced BCCs from the interfollicular epidermis, at least in part by enhancing Smo expression. This latter finding is consistent with the lack of visible tumors on ears and tail, sites lacking Smo expression, in Ptch1+/− mice.
