Hypoxia Treatment of Adipose Mesenchymal Stem Cells Promotes the Growth of Dermal Papilla Cells via HIF-1α and ERK1/2 Signaling Pathways

research Hypoxia Treatment of Adipose Mesenchymal Stem Cells Promotes the Growth of Dermal Papilla Cells via HIF-1α and ERK1/2 Signaling Pathways

1 citations , July 2023 in “International Journal of Molecular Sciences”

This study found that a hypoxic microenvironment enhanced the proliferation and pluripotency of adipose mesenchymal stem cells, promoting hair follicle formation and upregulating specific growth factors in Arbas Cashmere goats.

research Stress-induced premature senescence of dermal papilla cells compromises hair follicle epithelial-mesenchymal interaction

35 citations , January 2017 in “Journal of Dermatological Science”

This study suggests that stress-induced premature senescence of dermal papilla cells may contribute to hair follicle aging by impairing critical epithelial-mesenchymal interactions and promoting inflammatory cytokine production.

research EGFR marks a subpopulation of dermal mesenchymal cells highly expressing IGF1 which enhances hair follicle regeneration.

1 citations , May 2023 in “PubMed”

The researchers in this study identified a new subpopulation of dermal fibroblasts in neonatal murine dermis marked by EGFR, which they report contributes to hair follicle regeneration through the promotion of IGF1, potentially aiding in wound-induced hair follicle neogenesis.

research 891 Comparison of phenotypes and transcriptomes of mouse skin-derived precursors and dermal mesenchymal stem cells

April 2019 in “Journal of Investigative Dermatology”

This study reported that mSKPs and DMSCs share similarities in biological characteristics but exhibit distinct transcriptome profiles, with mSKPs being more immune-related and DMSCs more associated with differentiation and disease pathways.

research Rapid mechanosensitive migration and dispersal of newly divided mesenchymal cells aid their recruitment into dermal condensates

2 citations , September 2023 in “PLoS biology”

This study found that mesenchymal cells in mouse and chicken embryonic skin undergo a process of migration driven by tissue tension and WNT secretion, influencing their dispersal and integration into dermal condensates.

community Recent trials investigating mesenchymal stem cell derived exosomes demonstrate significant increases in anagen duration and hair shaft caliber by upregulating Wnt/beta-catenin pathways.

4 upvotes 3 weeks ago

Exosomes from mesenchymal stem cells can increase hair growth by enhancing anagen duration and hair shaft thickness through the Wnt/beta-catenin pathway. Phase 2 trials show improved hair counts over 24 weeks.

community New Hair Loss Cure: AMP-303 Is Back. It’s what PP405 should have been.

7 upvotes 5 months ago

AMP-303 and AMP-601 are new hair loss treatments targeting dermal papilla cells, with AMP-303 showing early efficacy in transitioning vellus hairs to terminal hairs after one injection. Further clinical trials are planned, and these treatments are seen as promising due to their biologic approach and less frequent application compared to daily treatments.

community Proof DHT is not the main cause of hair loss. TRPS1 Gene and Protein might be. PP405 won’t work. AMP-303 might!

153 upvotes 6 months ago

Hair loss may be linked to the TRPS1 gene and protein, not just DHT. Amplifica's AMP-303 targets mesenchymal stem cells and shows promise in treating hair loss, unlike Pelage's PP405.

community Anyone Try Microneedling with Exosomes/AAPE?

2 upvotes 4 years ago

User asks where to purchase exosomes/AAPE for microneedling hair loss treatment. Links to research on hair regeneration therapy, stem cell therapy, exosome therapy, and dermal exosomes provided.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 2 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.
