Summary (written by the submitters)
Scarring alopecia is an unresolved challenge characterized by scar formation following skin injury without hair follicle (HF) regeneration. Wound-induced hair follicle neogenesis (WIHN) is a model in which HFs regenerate after skin wounding. This study aimed to explore the mechanisms underlying WIHN, hinting for the new therapeutic strategies for scarring alopecia.

Our results indicated that keratinocytes were categorized into 8 subpopulations, with a notable increase in the proportion of INFU basal KCs in tissue with WIHN, which was validated by IF staining. Pseudotime analysis revealed that the marker gene Fst of INFU basal KC was activated earlier in tissue with WIHN. Fibroblasts were classified into 5 subpopulations, with an increase in the proportions of secretory reticular fibroblasts. Cell-cell communication analysis showed that interactions between INFU basal KC and secretory reticular fibroblasts were significantly enhanced. Enrichment analysis further demonstrated that extracellular matrix (ECM)-receptor interactions were significantly enriched in ligand-receptor interactions. Masson staining exhibited decreased collagen content in tissue with WIHN.These findings suggest that the importance of INFU basal KCs in WIHN and that the ECM reconstruction is crucial for WIHN. Our study contributes to a better understanding of the underlying mechanisms of WIHN.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE308939_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1333457 and SRA study SRP625632. Searching any of these in the dataset finder brings you back here.

Study design
6 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 6 sample titles: 6 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
