This study found that the BMP antagonist noggin induces hair growth in postnatal skin by neutralizing BMP4's inhibitory activity, potentially mediated by changes in Shh expression.

This study found that RXRα/RARγ heterodimers are necessary for retinoic acid-induced keratinocyte proliferation in the skin, while normal epidermal maintenance does not require RAR-mediated signaling.

This study found that hair follicle and interfollicular epidermis stem cells contribute differently to skin regeneration, with their persistence influenced by factors like spatial constraints and competition moderated by Notch suppression.

In this study, Nrf-2-expressing hair follicle mesenchymal stem cells showed the most significant therapeutic effect in a rat model of ulcerative colitis, suggesting a new potential treatment for the disease.

This study reported that an HS-associated NCSTN mutation in iPSC-derived skin organoids led to altered hair follicle stem cell differentiation and increased expression of proteins linked to HS inflammation.

This study found that increased MSI2 expression in hair follicle stem cells can delay hair growth by maintaining stem cell quiescence and repressing Hedgehog signaling.

This study describes the process of isolating and analyzing multipotent stem cells from mouse hair follicles for potential use in tissue engineering and regenerative medicine.

This article argues that a proposed merger between ISHRS and AACS would be detrimental to the ISHRS, but it presents no new research findings.

This study found that treating SM-MSCs with 150 μg/mL IGF-1 led to the highest increases in growth factor proteins BMP-2, FGF-18, and TGF-β1 in their conditioned media.

This review outlines strategies for preventing, identifying, and managing complications related to current MS therapies and reports no new clinical results, emphasizing the growing complexity in MS treatment regimens.

This study presents a novel in vitro assay using human folliculoid microspheres to research hair growth, which may facilitate preclinical testing of hair growth-modulatory agents.

This study found that skin organoids derived from iPSCs with an HS-associated NCSTN mutation showed defects in hair follicle stem cell differentiation and increased expression of inflammatory proteins related to hidradenitis suppurativa.

This study found elevated levels of IL-18 and free IL-18 in hidradenitis suppurativa patients compared to healthy controls, suggesting these cytokines may serve as novel biomarkers for disease activity, with correlations indicating their involvement in disease severity.

Sex and race affect immune responses and treatment outcomes in Hidradenitis suppurativa.

This study found that human hair follicle-derived mesenchymal stem cells effectively maintained human embryonic stem cells in an undifferentiated state, comparable to mouse embryonic fibroblasts under standard conditions.

This review outlines the transition from simple hair follicle organoids to immune-competent microphysiological systems, addressing limitations in replicating native hair follicle immune features and discussing their applications in disease modeling and regenerative medicine.

This report announces that the International Society of Hair Restoration Surgery received Accreditation with Commendation.

This study found that hair follicle stem cells from hidradenitis suppurativa patients showed alterations in cell cycle regulation and DNA replication, potentially linking genetic predisposition to the skin inflammation characteristic of the disease.

This study found that serum-free expanded hair follicle mesenchymal stem cells (hfMSCs), derived from hair plucking, significantly improved cartilage repair in a murine model despite minimal engraftment, suggesting their effectiveness through a paracrine mechanism.

This study found that intravenous transplantation of human hair follicle-derived mesenchymal stem cells improved trabecular bone mass in osteoporotic mice by enhancing bone formation and reducing bone resorption.

This study suggests that human mesenchymal stem cells have the potential to differentiate into dermal papilla cells both in vitro and in vivo.

This study found that human hair follicle-derived mesenchymal stem cells maintained their proliferation and differentiation potential when cultured with acidic fibroblast growth factor, basic fibroblast growth factor, or epidermal growth factor.

This study identified a distinct CD49fhigh mesenchymal stem cell subpopulation in the dermis that supports hair follicle development and maintenance via Notch signaling activation.

This study suggests that in hidradenitis suppurativa, MMP-induced matrix alterations may contribute to inflammation by releasing active peptides and inflammatory factors in the extracellular matrix.

In this study, Exosome Hypoxia Mesenchymal Stem Cells significantly reduced inflammation and promoted hair follicle regeneration by normalizing IL-1Beta and IGF-1 levels in fluconazole-induced alopecia-like Wistar rats.

This study showed that exosomes from hyaluronic acid-primed induced mesenchymal stem cells promote hair growth by enhancing proliferation and migration of hair follicle dermal papilla cells and modulating key growth factors and signaling pathways, potentially counteracting the effects of DHT-induced hair loss.

This trial found that intradermal injections of the Hair Stimulating Complex were well-tolerated and effectively stimulated hair growth and prevented hair loss in male pattern baldness participants over 18 weeks.

This study found that when NFIB was removed in adult mouse hair follicle stem cells, it did not affect their maintenance but unexpectedly led to increased proliferation and differentiation of nearby melanocyte stem cells.

This study found that hair follicle stem cells show good biocompatibility with a heterogeneous bladder acellular matrix in vitro and in vivo, supporting potential use in bladder repair.
