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

This study indicates that Fructus panax ginseng extract may promote hair growth by increasing proliferation in human hair dermal papilla cells and lengthening the anagen phase in mice.

This study found that the natural extract e-CAF promotes the proliferation and migration of human hair dermal papilla cells in vitro, suggesting potential benefits for skin regeneration and tissue repair.

In this study, Lespedeza bicolor extract was found to enhance dermal papilla cell proliferation and extend the anagen phase in mice, suggesting its potential as a treatment for alopecia.

This review examines advancements in hydrogel formulations aimed at preventing dermal fibrosis and promoting scarless wound healing, highlighting their role in regulating myofibroblast differentiation and controlling the wound microenvironment.

This study found that topical application of metformin significantly enhanced skin regeneration in mechanically stretched skin in rats, likely by boosting the proliferation of skin-derived stem cells.

This study highlights IGF-1's role in promoting hair follicle proliferation, vascularization, and growth, suggesting its potential as a treatment target for hair loss disorders like androgenetic alopecia, though more research on delivery methods and long-term effects is needed.

This study demonstrated that adipose derived stem cells nanovesicles enhanced hair growth and reduced sebum secretion in androgenetic alopecia, showing effects comparable to minoxidil in laboratory and mouse models.

This study reported that in animal studies of androgenetic alopecia, a biodegradable microneedle patch releasing glutamic acid promoted hair regeneration more effectively than daily minoxidil, with higher hair follicle counts and less frequent dosing, showing the potential for clinical application.

Intermittent fasting slows hair growth by damaging hair follicle cells.

This study found that modifying adipose-derived stem cells to overexpress the adhesion protein JAM-A increased the adhesion and resilience of dermal papilla cells in the context of androgenic alopecia, potentially facilitating hair regrowth despite challenges such as damage from dihydrotestosterone and macrophages.

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.

This review discusses the relationship between vitamin K and osteoarthritis, noting that while lower vitamin K levels are associated with increased osteoarthritis, the effects of vitamin K supplementation on the condition remain unclear due to a lack of clinical trials.

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 study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

This review discusses the use of dermal regeneration templates for treating burn injuries and other wounds, highlighting their effectiveness in reducing scars and aiding in regenerative processes, but reports no new clinical results.

This review explores the role of hair follicle dermal stem cells in skin regeneration and restorative therapies, but it reports no new experimental results.

This review discusses recent advances in hair regeneration strategies, including mechanical stimulation and complementary therapies like MSC transplantation and platelet-rich plasma, and reports no new clinical results.

This review discusses strategies for regenerating cutaneous nerve function in burn patients and highlights the potential role of autologous skin-derived adult stem cells in improving sensory recovery, but reports no new experimental findings.

This study found that ECMs from papillary and dermal papilla fibroblasts support normal basement membrane formation, suggesting potential improvements for therapeutic biomaterials in skin engineering.

This review found limited but suggestive evidence that Calcium Hydroxylapatite may promote skin regeneration through increased collagen production, cell proliferation, and angiogenesis, although most studies had methodological limitations.

In this study, researchers established five new immortalized human dermal papilla cell lines from a male with androgenetic alopecia, which may serve as valuable tools for hair research.

This review discusses recent advances in using stem cells for skin repair and regeneration after severe burn injuries, but it reports no new clinical results.

Dermagraft and Dermalogen had a lot of granulation, while Alloderm, Integra, and ADM had good blood vessel growth for skin healing.

This study identified and characterized progenitor cells from equine feet that may play a role in the pathogenesis and recovery of laminitis, suggesting potential therapeutic targets for treatment.

This study found that exosomes derived from bovine colostrum, compared to those from human stem cells, significantly increased hair follicle growth and regeneration in vitro.

This study found that a new-type artificial xenogenic derma exhibited better biocompatibility and dermal tissue regeneration ability compared to cross-linked acellular dermal matrix in a mouse model.

Mechanical stretching can improve or hinder skin regeneration depending on duration.

This study introduces a method using lentiviral delivery in mice to expedite analysis of factors crucial for hair follicle morphogenesis by enabling rapid gain- or loss-of-function studies.

This study explored the role of Twist2 in fetal wound healing in embryonic mice, observing that its expression was vital for scarless regeneration and normal hair follicle formation; Twist2 knockdown led to visible scars and defective follicle formation.
