Single cell RNA sequencing analysis of the center, edge and non-wounded regions of healing skin on day 11 post-wounding in wild type mice

ABSTRACT: We applied single-cell RNA sequencing to investigate specific type of cell populations and their gene expressions on the day of wound closure (post-wounding day 11-12) at the center and edge of the re-epithelialized mouse wound site (1 cm² of whole skin was removed, with samples pooled from 10 mice). Skin samples from non-wounded area were collected as control.

Array analysis of wound induced hair neogenesis (early stage)

Project description:Mice were wounded and skin samples of the scar collected on the day of wound closure. We compared Mixed mice (B6/FVB/SJL), a strain of high regeneration, versus C57bl mice, a strain of low regeneration. Whole skin biopsies of wound scars were submitted for Affymetrix Exon arrays. 4 mice each of 2 distinct strains of differing regeneration levels were collected.

Epidermal gene expression in wound healing and after ex vivo injury

Project description:Human in vivo skin wound: Non-wounded skin was obtained by taking punch biopsies from three healthy donors (donor 1,2 and 3). The samples were termed 'skin day 0 in vivo wound'. Skin wound samples were retrieved by making new punch biopsies from the edge of the original biopsies after four days. These samples were termed 'skin day 4 in vivo wound'. As much dermal tissue as possible was removed by dissection to make sure mainly epidermis was present in the samples. The samples were washed in NaCl to possible remove infiltrating inflammatory cells before RNA isolation. Ex vivo skin wounds: Skin was obtained from three healthy donors following reduction surgery (donor 1, 2, and 3). As much dermal tissue as possible was removed dissection. These samples were termed 'skin day 0 ex vivo wound'. Skin was sliced into 1x10 mm slices and incubated in keratinocyte medium for four days with either 1:1000 fold dilution of DMSO or 10 micromolar AG-1478 (dissolved in DMSO). Again as much dermal tissue was removed by dissection as possible before RNA was isolated. These samples were termed 'skin day 4 ex vivo wound' and 'skin day 4 AG-1478 ex vivo wound'. By comparing the gene expression day 4 in ex vivo wound with in vivo wounds it was possible to see which part of the gene expression in wounded skin that was due to the epidermal reaction to injury and how much was due to stimuli from infiltrating inflammatory cells absent in the ex vivo skin wounds. By comparing the data from ex vivo skin wounds day 4 with and without the EGFR-inhibitor AG-1478, it was possible to look at the importance of the EGF-receptor of EGFR for the gene expression in ex vivo wounded skin.

scRNA-Seq for mouse wounded and non-wounded samples

Project description:Lineage negative (CD45- & CD31-) cells were isolated from uninjured skin and day 5 dorsal skin wound beds of 7-week-old AdipoqCre; mT/mG mice using FACS. This experiment describes multiple subsets of wound bed myofibroblasts and identifies that Adipoq-traced cells contribute to the myofibroblast pool in wound beds.

Single cell RNA sequencing analysis of the center region of healing skin at wound day 11 in wild type mouse

Project description:We have applied single_x0002_cell RNA sequencing analysis to investigate keratinocyte populations and their specific gene expression on the day of would closure (post wounding day 11-12) at the center of re-epithelialized mouse wound site (1 cm2 of whole skin was removed, multiple pooled mice, n = 10). Viable cells from single cell suspension were selected by sorting and single cell library was prepared by 10x Genomics and sequenced by Illumina NovaSeq 6000. Downstream bioinformatic analysis of single cell RNAseq was performed by using Seurat package in R. Clusters of cells were denoted according to their identity. Keratinocytes were identified from the entire sample of cells using known keratinocyte markers. Specific gene expression over the keratinocytes were visulaized by heatmap. Overlap expression of Cd14, Tlr3, Krt15, Krt19 and Rarα at the day of wound closure supports morphogenesis.

Array analysis of wound induced hair neogenesis (late stage)

Project description:Mice were wounded and measured for regeneration starting 4 days after wound closure with simultaneous measurement of hair follicle neogenesis and biopsing. At each time point, RNA was collected from one mouse with high number of regenerated follicles and one without regenerated follicles. Whole skin biopsies of wound scars were submitted for Affymetrix Exon arrays. 3 replicates of mice with high number of regenerated follicles, 3 replicates of mice with no regenerated follicles; each pair taken at a different date after wound closure.

Leading edge airway epithelial cell responses to in vitro wounding

Project description:The airway epithelium of asthmatics is characterized by intrinsically abnormal wound repair that may contribute to disease pathobiology. In this study, we show that in asthma, the airway epithelial cells at the leading edge of a wound display aberrant migration patterns, reduced expression of α5 and β1 integrin subunits at baseline and during wound repair, resulting in dysregulated cell migration and an inability to fully repair. Transcriptional profiling identified the PI3K/Akt signaling pathway as the top upstream transcriptional regulator of integrin α5β1. Significantly, activation of Akt signaling enhanced airway epithelial repair in cultures derived from asthmatic children via upregulation of α5 and β1 integrin subunits. Conversely, inhibition of the PI3K/Akt signaling pathway in airway epithelial cultures from non-asthmatic children attenuated epithelial repair and reduced α5 and β1 integrin expression. Importantly, the FDA-approved drug celecoxib, and its non-COX2 inhibitory analogue dimethyl-celecoxib, also stimulated the PI3K/Akt/integrin α5β1 axis and restored airway epithelial repair in cells from asthmatics. Thus, targeting the PI3K/Akt pathway may represent a novel therapeutic avenue for asthma.
