This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

Researchers successfully isolated and identified key stem cells in human hair follicles, which could help develop new skin and hair treatments.

This study concluded that bone morphogenetic proteins are crucial for hair follicle stem cell differentiation and that their downregulation by androgens may contribute to the development of androgenetic alopecia.

This study found that Bone morphogenetic proteins (BMPs) play a crucial role in dermal papilla cells' ability to induce hair follicle stem cell differentiation, and that androgens may impair this process by downregulating BMPs.

This review discusses photothermal agent hybrids in hydrogels for antibacterial action, angiogenesis, and osteogenesis in tissue engineering, but reports no new experimental findings.

This study found that gelatin sponges used as scaffolds in rats with deep wounds and periosteal defects enabled regeneration of diverse tissue types, including periosteum, skin, and appendages, highlighting the role of vascular niche formation.

This review explores the potential of using genetically-manipulated stem cells as both therapeutic agents and gene delivery vehicles for enhanced wound regeneration, but it reports no new clinical results.

This review examines experimental studies on the synergistic use of platelet-rich plasma and adipose-derived mesenchymal stem cells for wound healing in animal models, without reporting new clinical outcomes.

This review discusses the role of heparan sulfate proteoglycans in regulating stem cell fate and highlights their potential as targets for addressing hair loss, without reporting new clinical results.

This case study reported a 23-year-old woman with chronic myeloid leukemia who developed permanent hair loss after chemotherapy and did not respond to topical minoxidil treatment.

This study found that inactivating CerS4 in mice led to hair follicle stem cell exhaustion and hair loss, indicating its role in regulating hair regeneration through ceramide composition and signaling pathways.

This study validated a protocol for inducing surface ectoderm differentiation from human induced pluripotent stem cells and highlighted the role of TGFβ signaling pathways in this process.

This study suggests that PDGFA and BMP2 play a role in the hair follicle cycle in cashmere goats, with PDGFA particularly involved in activating the growth phase.

This study found that Guilu Erxian Glue significantly alleviates various doxorubicin-induced side effects in mice, enhancing exercise capacity and reducing oxidative stress and inflammation.

In vivo using the C3H mouse model, this study observed that BST2 expression occurs before hair loss in alopecia areata and is followed by an increase in epidermal γδ T cell numbers.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.

In this case report, two young women with female pattern hair loss experienced significant hair regrowth without adverse effects after six months of treatment with bone-marrow-derived mesenchymal stem cells and their extracellular vesicles, suggesting potential for this approach when conventional treatments fail.

Skin-associated cartilage cells can influence hair growth by altering specific signaling pathways.

In this study, all-trans retinoic acid was found to protect against oxidative stress-induced apoptosis in cultured hair cell-like cells.

This study investigated how secretions from cultured human hair follicle-derived keratinocytes affect gene expression in human follicle dermal papilla cells to understand their signaling interactions.

In this study, transgenic mice with active BMPR1A signaling in the epidermis had impaired hair follicle morphogenesis and showed age-related hair loss, implicating BMP signaling in hair follicle development and homeostasis.

The demineralized bone matrix scaffold is better for cell attachment than the mineralized bone allograft.

The study observed that the tumor suppressor activity of bone morphogenetic proteins in mouse skin epithelium depends on Noggin levels, inhibiting Wnt and Shh signaling pathways to prevent tumor initiation and progression.

This case report highlights that new onset non-scarring alopecia after allogeneic stem cell transplantation may indicate chronic graft-versus-host disease.

This review explores the diverse physiological roles of the vitamin D endocrine system, discussing current research on receptor structure, transcription details, murine models, and alternative receptors, but reports no new findings.

This review discusses the diverse roles of the TRPS1 gene in regulating cartilage, kidney, and hair follicle development, highlighting its functions and interactions, but provides no new experimental results.

This study found that hair follicle matrix progenitors differentiate into various layers asynchronously, with early progenitors forming the companion layer and later progenitors generating the inner root sheath and hair shaft.

In this study, homozygous VDR null mutant mice exhibited nonfunctional vitamin D receptors, leading to growth abnormalities and revealing the limited physiological importance of vitamin D pathways outside the classical receptor.

This review discusses recent research and applications of RADA16 and RADA16-based peptide scaffolds in biomedicine, including their roles in tissue repair and drug delivery, but reports no new clinical results.

The study found that adipose-derived mesenchymal stem cells obtained via laser-assisted liposuction with selective photo-stimulation are comparable in differentiation potential and tumorigenic risk to those from conventional liposuction for cell therapy applications.
