In this study, chick embryo extract enhanced neuronal differentiation and trophic factor expression in rat hair follicle stem cells, suggesting potential improvements for stem cell therapies in neurodegenerative diseases.

This review discusses the potential of bone marrow mesenchymal stem cell-derived cytokines and growth factors as a promising alternative to conventional treatments for androgenetic alopecia, given their favourable outcomes in hair regrowth and follicle repair.

This study found that progesterone and its metabolite, allopregnanolone, provided anti-anxiety and anti-depressive effects in female mice, potentially independent of nuclear progestin receptors but requiring 5α-reduction and estradiol's influence on brain-derived neurotrophic factor.

This review discusses the regenerative processes of lizard tails, particularly focusing on the diversity in blastema development across different species, and reports no new findings.

This review highlights that platelet-rich plasma and adipose-derived stem cell therapy may offer safe and promising improvements for managing symptoms of genital lichen sclerosus, with a potential synergistic benefit when combined.

In this study, chitosan membranes enhanced melanocyte proliferation and survival by supporting both cell-cell and cell-substrate interactions, unlike polyvinyl alcohol membranes which only facilitated cell-cell interactions.

This review discusses advancements in stem cell therapy for cutaneous radiation syndrome, highlighting the potential of various stem cell sources to improve wound healing and reduce symptoms, but reports no new clinical results.

In this study, intranasal delivery of hair follicle-derived stem cells improved neurological function and reduced brain damage in a rat model of ischemic stroke.

The authors suggest that male-pattern hair loss may be linked to neuropathy caused by tension on scalp nerves, potentially worsened by testosterone, and propose electrical stimulation as a temporary treatment.

In this case series, Xiang Chen reported instances of nail damage and hair loss following herpes zoster, noting the need for further exploration into the mechanisms and potential risk factors such as tuberculosis infection and kidney transplantation.

This article reviews the dermatological challenges and cultural influences affecting India's aging population, noting that while pigmentary disorders and cosmetic dermatology are prevalent, cutaneous cancers remain rare and often go undetected.

This review discusses the potential of secretome derived from stem cells for treating alopecia areata and reports no new clinical results; the authors suggest the need for further human trials.

This study observed that using transfected human cord blood cells enhanced skin wound healing in rats by promoting angiogenesis and earlier termination of proliferation compared to untransfected cells.

This article reviews the complex causes of scalp pruritus and emphasizes the importance of thorough diagnosis, though some cases may lack a clear cause and rely on empirical treatment to alleviate symptoms.

This study observed a higher incidence of telogen effluvium from July to October, suggesting a summer-related effect in populations above the Tropic of Cancer, possibly influenced by ultraviolet light.

This review discusses the therapeutic potential of stem cells from postnatal tissues for regenerative medicine, emphasizing their paracrine effects and the pluripotent potential of very small embryonic-like stem cells.

This review discusses the relationship between insulin regulation and hyperandrogenemia in polycystic ovary syndrome, suggesting potential benefits of insulin-lowering treatments for ovarian function but reporting no definitive results for hair-related symptoms.

This review discusses various treatments for androgenic alopecia, highlighting FDA-approved options and other commonly used therapies, but reports no new clinical results.

This study reviews existing literature on regenerative therapy for androgenetic alopecia, highlighting that integrating growth factors, biotin, D-pantenol, and other active ingredients using the Vittahair protocol may enhance hair follicle regeneration, increase hair density, and improve hair quality, providing a precise and evidence-based treatment alternative.

This review discusses the mechanisms and potential therapeutic benefits of mesenchymal stromal cell-derived extracellular vesicles delivered via biomaterials, but reports no new clinical results.

This review discusses the potential impact of endocrine-disrupting chemicals and body size on pubertal onset and progression, highlighting critical gaps and priorities for future research without presenting new clinical results.

This review discusses the advancements in intraoperative stem cell therapies and highlights their potential to improve hair regrowth, but it reports no new clinical results.

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

This study suggests that human placenta treatment may promote hair regrowth in chemotherapy-induced alopecia by inhibiting apoptosis and encouraging hair follicle proliferation in a mouse model.

Environmental factors and exposure to toxins may contribute to male infertility by affecting sperm and hormone function.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

This study in mice demonstrated that stress or nerve growth factor injection increases sensory neuron activity related to skin innervation, suggesting a strong connection between stress perception and neurogenic skin inflammation.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

This study observed that epidermal growth factor and fibroblast growth factor have distinct roles in sheep skin, with EGF involved in differentiation and FGF in bulb proliferation and fiber growth.

This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.
