This study observed that human hair follicles with a completely destroyed bulb can regenerate after being grafted onto immunodeficient mice, entering a shortened dystrophic telogen followed by anagen phase.

This study observed that human hair follicles were able to regenerate fiber-forming structures after the bulb was amputated and transplanted onto athymic mice, suggesting a general regenerative capacity.

In this study, researchers detailed how hair follicles regenerate after microsurgical amputation, observing a wound reaction involving dynamic dermal-epidermal interactions and changes in extracellular matrix components.

Both main and alternative Wnt signaling are important for regrowing rodent whisker follicles.

This study found that transplanting trichogenous dermal cells significantly enhanced the restoration of in vivo-damaged hair follicles in a nude rat model, with a combination of dermal papilla and sheath cells proving more effective than either cell type alone.

Tanshinone Capsule may help regrow hair by boosting specific cell signals.

This study found that only one upper portion of a bisected human hair follicle successfully regenerated a complete new follicle with a pigmented hair in nude mice, although the overall success rate was very low.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

This article discusses the extended theory of selective photothermolysis and does not report new clinical results; the authors explore potential applications in hair removal techniques.

This review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.

This study found that intense pulsed light treatment primarily targets pigmented structures in hair follicles and may damage dermal papilla cells at high energy levels, but stem cells are mostly spared.

This chapter discusses the concepts of regeneration and homeostasis, noting that in vertebrates, regeneration is limited to certain tissues like liver, blood, and bone.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

This article reviews treatment options for male androgenetic alopecia, including minoxidil, 5 alpha reductase inhibitors, and hair transplantation, but reports no new clinical findings.

This review discusses the multifaceted roles of hair follicles in skin health, including potential contributions to skin neoplasias, and reports no new results.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This study found that Flightless I (Flii) positively influences hair follicle regeneration in rodents, contrasting with its known negative effect on wound healing.

This study identified FP-1 as a highly specific extracellular matrix protein in follicular papilla cells, which may play a role in hair growth regulation during specific hair cycle phases.

This review discusses the potential of single cell technologies to improve understanding and treatment of impaired wound healing and reports no new clinical results.

This study reports the first instance of skin autotomy in mammals, specifically in African spiny mice, and suggests they may possess a greater regenerative capacity than previously understood, possibly offering insights for regenerative medicine.

This article reviews the role of skin appendages in wound healing and appendage regeneration, discussing cellular and molecular mechanisms but reports no new experimental findings.

This review discusses the development and advances in studying trichogenic dermal cells for hair follicle morphogenesis, summarizing methods, bioassays, and molecular markers, but reports no new research findings.

This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.

In this study, co-grafting human keratinocytes with murine dermal papilla-enriched cells produced hair follicle-like structures, but without regular hair formation, suggesting anomalous folliculogenesis.

This review discusses recent advances in hair follicle biology, regeneration, and tissue engineering, highlighting emerging therapeutic opportunities, and reports no new experimental results.
