Single-cell sequencing quantitative analysis of skin tissues of wild-type and Chrna5-/- mice treated with vaseline

ABSTRACT: Purpose: To understand the molecular processes and cell subsets involved in an increase in the psoriatic inflammatory response in Chrna5 signaling compared with WT mice, we performed single-cell sequencing with dorsal skin tissues after vaseline treatment. Methods: Skin mRNA profiles of wile-type (WT) and cholinergic receptor nicotinic alpha 5 subunit knockout (Chrna5-/-)mice were generated by deep sequencing. The samples of KO and WT mice after vaseline treatment were processed in terms of alignment, barcode assignment, and UMI counting with Cell Ranger, version 3.0.2 (https://github.com/10XGenomics/cellranger) count pipeline. Results: The cell clustering analysis, the heat map analysis, the cell subpopulations of keratinocytes analysis, the gene enrichment analysis and signal pathway analysis were all carried out. The results of these studies indicated that Chrna5 knockout may have a significant effect on the keratinocytes after vaseline treatment. Conclusions: These results revealed the potential role of Chrna5 in the occurrence and development of normal skin.

Project description:Hair follicle formation depends on reciprocal epidermal-dermal interactions and occurs during skin development, but not in adult life. This suggests that the properties of dermal fibroblasts change during postnatal development. To examine this, we used a PdgfraEGFP mouse line to isolate GFP-positive fibroblasts from neonatal skin, adult telogen and anagen skin and adult skin in which ectopic hair follicles had been induced (EF skin) by transgenic epidermal activation of beta-catenin. We also isolated epidermal cells from each mouse. The gene expression profile of EF epidermis was most similar to that of anagen epidermis, consistent with activation of beta-catenin signalling. In contrast, adult dermis with ectopic hair follicles more closely resembled neonatal dermis than adult telogen or anagen dermis. In particular, genes associated with mitosis were upregulated and extracellular matrix-associated genes were downregulated in neonatal and EF fibroblasts. We confirmed that sustained epidermal beta-catenin activation stimulated fibroblasts to proliferate to reach the high cell density of neonatal skin. In addition, the extracellular matrix was comprehensively remodelled, with mature collagen being replaced by collagen subtypes normally present only in developing skin. The changes in proliferation and extracellular matrix composition originated from a specific subpopulation of fibroblasts located beneath the sebaceous gland. Our results show that adult dermis is an unexpectedly plastic tissue that can be reprogrammed to acquire the molecular, cellular and structural characteristics of neonatal dermis in response to cues from the overlying epidermis. We have isolated the following populations of cells from mouse back skin by flow cytometry: 1A) GFP+ WT neonatal dermal fibroblasts, 1B) ItgA6+ WT neonatal epidermal keratinocytes, 2A) GFP+ WT telogen dermal fibroblasts, 2B) ItgA6+ WT telogen epidermal keratinocytes, 3A) GFP+ D2 transient activation (anagen) dermal fibroblasts, 3B) ItgA6+ D2 transient activation (anagen) epidermal keratinocytes, 4A) GFP+ D2 sustained activation (ectopic follicles) dermal fibroblasts, 4B) ItgA6+ D2 sustained activation (ectopic follicles) epidermal keratinocytes
