Hoxc-Dependent Mesenchymal Niche Heterogeneity Drives Regional Hair Follicle Regeneration. Cell Stem Cell 2018; 23:487-500.e6. [PMID: 30122476 DOI: 10.1016/j.stem.2018.07.016] [Citation(s) in RCA: 40] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2017] [Revised: 05/09/2018] [Accepted: 07/24/2018] [Indexed: 11/17/2022]
Abstract
Mesenchymal niche cells instruct activity of tissue-resident stem and progenitor cell populations. Epithelial stem cells in hair follicles (HFs) have region-specific activity, which may arise from intrinsic cellular heterogeneity within mesenchymal dermal papilla (DP) cells. Here we show that expression of Hoxc genes is sufficient to reprogram mesenchymal DP cells and alter the regenerative potential of epithelial stem cells. Hoxc gene expression in adult skin dermis closely correlates with regional HF regeneration patterns. Disrupting the region-specific expression patterns of Hoxc genes, by either decreasing their epigenetic repression via Bmi1 loss or inducing ectopic interactions of the Hoxc locus with an active epigenetic region, leads to precocious HF regeneration. We further show that a single Hoxc gene is sufficient to activate dormant DP niches and promote regional HF regeneration through canonical Wnt signaling. Altogether, these results reveal that Hoxc genes bestow mesenchymal niches with tissue-level heterogeneity and plasticity.

[PMID: 26718736 DOI: 10.1111/cga.12153] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2015] [Revised: 12/24/2015] [Accepted: 12/24/2015] [Indexed: 12/29/2022]
Abstract
Homeobox genes play important roles in craniofacial morphogenesis. However, the characteristics of the transcription factor Hoxc during palate formation remain unclear. We examined the immunolocalization patterns of Hoxc5, Hoxc4, and Hoxc6 in palatogenesis of cleft palate (Eh/Eh) mice. On the other hand, mutations in the FGF/FGFR pathway are exclusively associated with syndromic forms of cleft palate. We also examined the immunolocalization of Fgfr1 and Erk1/2 to clarify their relationships with Hoxc in palatogenesis. Some palatal epithelial cells showed Hoxc5 labeling, while almost no labeling of mesenchymal cells was observed in +/+ mice. As palate formation progressed in +/+ mice, Hoxc5, Hoxc4, and Hoxc6 were observed in medial epithelial seam cells. Hoxc5 and Hoxc6 were detected in the oral epithelium. The palatal mesenchyme also showed intense staining for Fgfr1 and Erk1/2 with progression of palate formation. In contrast, the palatal shelves of Eh/Eh mice exhibited impaired horizontal growth and failed to fuse, resulting in a cleft. Hoxc5 was observed in a few epithelial cells and diffusely in the mesenchyme of Eh/Eh palatal shelves. No or little labeling of Fgfr1 and Erk1/2 was detected in the cleft palate of Eh/Eh mice. These findings suggest that Hoxc genes are involved in palatogenesis. Furthermore, there may be the differences in the localization pattern between Hoxc5, Hoxc4, and Hoxc6. Additionally, Hoxc distribution in palatal cells during palate development may be correlated with FGF signaling. (228/250 words) © 2016 Japanese Teratology Society.
