几项研究已经报道了将成体细胞诱导成汗腺样细胞;然而,缓慢的转化和低效率限制了基于细胞的治疗的潜力。在这里,我们发现转录因子FoxC 1的过度表达足以将表皮细胞重编程为诱导功能性汗腺样细胞(iSGCs)。iSGCs表达分泌相关基因,在胎儿SGCs(P5)和成人SGCs(P28)之间具有全局基因表达谱。此外,移植到烧伤小鼠模型中的iSGCs促进伤口修复和汗腺再生。我们进一步证明Foxc 1上调BMP 5的转录,BMP 5负责细胞类型的转变。总的来说,这项研究表明,表皮细胞的谱系重编程为iSGCs提供了一个很好的细胞来源和一个有前途的再生策略,用于无汗症和少汗症。
Several studies have reported inducing adult cells into sweat gland-like cells; however, slow transition and low efficiency limit the potential for cell-based treatment. Here, we show that overexpression of the transcription factor FoxC1 was sufficient to reprogram epidermal cells to induced functional sweat gland-like cells (iSGCs). The iSGCs expressing secreting-related genes, had a global gene expression profile between fetal SGCs (P5) and adult SGCs (P28). Moreover, iSGCs transplanted into the burn mice model facilitated wound repair and sweat gland regeneration. We further demonstrated that the Foxc1 upregulated BMP5 transcription and BMP5 is responsible for the cell-type transition. Collectively, this study shows that lineage reprogramming of epidermal cells into iSGCs provides an excellent cell source and a promising regenerative strategy for anhidrosis and hypohidrosis.
