Mesenchymal Stem Cell Exosome Study on Hair Follicle Rejuvenation

Shiyue Cui's research document on figshare, last updated April 22, 2026, details a study on human umbilical cord mesenchymal stem cell-derived exosomes. The 1.2 MB DOCX file presents experimental results showing exosome treatment reduced senescent cells from 67.5% to 21.4%, upregulated COL17A1 mRNA by 2.67-fold, and achieved 92.4% hair coverage in mice versus 45.6% for controls.

Use Cases

• Analyze the molecular mechanism of hair follicle rejuvenation based on the described miR-21-5p/DKK2/Wnt/β-catenin/COL17A1 axis.
• Benchmark treatment efficacy for hair regeneration based on the reported metrics like SA-β-gal reduction and hair coverage percentage.
• Study exosomal miRNA cargo and its targets based on the identification of miR-21-5p as the most abundant exosomal miRNA.
• Compare cell-free therapeutic strategies against traditional treatments like minoxidil based on the performance data provided.

Strengths

• Includes specific quantitative results, such as reducing SA-β-gal-positive cells from 67.5% to 21.4%.
• Reports fold-changes in gene expression (COL17A1 mRNA upregulation by 2.67-fold) and comparative treatment outcomes (92.4% vs 45.6% hair coverage).
• Licensed under CC-BY-4.0, permitting open sharing and adaptation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 1.2 MB DOCX file, which may require parsing to extract structured data.
