This study found that the controlled release of specific growth factors from biodegradable hydrogels significantly enhanced hair follicle growth and hair shaft length in mice compared to growth factors in solution.

This review discusses the potential of stem cell secretome in regenerative medicine and suggests that its paracrine effects, rather than direct cell replacement, may drive therapeutic benefits.

This study found that insulin-like growth factor-I and hepatocyte growth factor increased the chemotactic migration of human hair outer root sheath cells, suggesting these factors have both growth stimulatory and chemotactic effects.

This study found that low-dose UVB radiation enhances the survival, migration, and hair growth-promoting capacity of adipose-derived stem cells in mice through the generation of reactive oxygen species.

This report reviews current advances in hair follicle regeneration for tissue-engineered skin grafts and highlights the feasibility and challenges of creating human hair follicles in this setting, suggesting key bioengineering requirements.

In this study using a mouse model and human hair follicle cells, shikimic acid was found to promote hair growth and may serve as a new therapeutic agent for alopecia.

This article reviews the roles and mechanisms of stem and progenitor cell migration in adult organs for tissue homeostasis and regenerative medicine, but reports no new experimental results.

This study found that baicalin activates Wnt/ß-catenin signaling in human dermal papilla cells, increasing alkaline phosphatase expression, growth factor expression, and promoting hair growth in mice.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

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 demonstrated that dermal papilla cells are molecularly distinct from fibroblasts and identified many novel molecules, including a new member of the CTGF protein family.

In this study, cyclosporine A stimulated hair growth in mouse vibrissae organ culture by promoting matrix cell proliferation and altering growth factor expression.

This article discusses the early development of hair follicles with a focus on the formation of epidermal thickenings called placodes, reporting no new experimental results.

This review explores the potential link between psoriasis and metabolic syndrome, focusing on how disturbances in growth factors may connect these conditions and contribute to symptoms like keratinocyte proliferation and inflammation.

This article discusses the concept of telogen effluvium, introduced in 1961, characterized by diffuse scalp hair loss due to various triggers, and reports no new clinical findings.

This study suggests that the InlB321/15 protein may accelerate wound healing by increasing cell proliferation and reducing wound closure time in both cell culture and mouse models.

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

This chapter reviews traditional and tissue-engineered treatments for skin defects and discusses advances in bioengineered skin constructs, but it presents no new experimental results.

This review investigates how various intrinsic factors—such as growth factors, cytokines, chemokines, and interferons—regulate hair growth through evidence gathered from in vitro and in vivo studies, highlighting the need for further research in human subjects to validate these findings.

This study found that Rubus coreanum extract promotes hair growth in mice, but its effects are not due to inhibition of specific enzymatic activities or growth factor expression.

This study found that both genetic and environmental factors influence appearance-related aging in women, with skin wrinkling, hair graying, and sun damage significantly affecting perceived age more than chronological age.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This study suggests that dermal stem/progenitor cells can be enriched by intracellular granularity and display high proliferation and differentiation potential in vitro, distinguishing them from other fibroblasts and progenitors.

This study found that the transcriptome of skin stem cells in mice changes significantly with age, revealing specific age-dependent biological programs and transcriptional hubs.

In this study, FGF12 was found to promote hair growth in mice by inducing the anagen phase of hair follicles, suggesting potential for hair loss therapy.

This review discusses various treatments for noncicatricial alopecias, such as androgenetic alopecia and alopecia areata, including mesotherapy, microneedling, and platelet-rich plasma therapy, noting that outcomes vary across these procedures.

The study concluded that the Exprecell™ device for preparing anticoagulant-free f-PRF increases volume yield and simplifies the process while maintaining biological activity comparable to conventional methods, suggesting potential clinical utility.

This study found that early-onset male androgenetic alopecia is associated with abnormal lipid metabolism and lower levels of certain serum markers, which may serve as risk factors or protective factors for the condition.
