This study suggests that high proliferative activity and peripheral invasion are key indicators of malignancy in canine sebaceous gland tumours. It also reports a higher incidence of circumanal gland and testicular tumours, indicating a possible androgen-related pathway in tumour development.

This study reported that ELL is crucial for maintaining the proliferative capacity of the basal layer in human epidermal keratinocytes by stabilizing RNA polymerase II at the transcription start site.

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.

This study found that platelet-rich plasma therapy led to significantly increased hair growth and density compared to placebo in patients with androgenic alopecia over six months.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

This study found that exposure to 50 Hz electromagnetic fields enhanced hair regrowth in mice by increasing stem cell proliferation and keratinocyte growth factor expression, suggesting potential benefits for hair loss treatment.

This study found that bee venom accelerated the transition from the telogen to anagen phase in mice, increasing hair growth by day 14, and suggested that bee venom may enhance adipose-derived stem cell activity by upregulating growth factor secretion.

This study found that Rumex japonicus Houtt. root extract promoted hair growth by enhancing cell proliferation and preventing apoptosis in human dermal papilla cells and HaCaT cells, as well as in a mouse model.

This study found that a blackcurrant extract with phytoestrogen activity increased hair number and stem cell marker expression in a menopausal rat model, suggesting a potential benefit for hair loss.

This study found that the immune-competent B6. Cg‐Tyr c−2J Hr hr /J congenic mouse line had a more pronounced delayed sunburn response and different proliferative skin reactions to UV exposure compared to SKH 1 mice.

This case report describes a rare instance of trichogerminoma with unusually numerous mitotic figures and a higher Ki67 proliferative rate, distinguishing it from previously documented cases.

This study found that Schistosoma mansoni cercariae stimulate epidermal keratinocytes in mice, initiating pro-inflammatory responses and barrier repair mechanisms akin to those in wound healing.

This study found that foot shock stress prolonged the telogen stage and delayed anagen induction in the hair cycle of non-depilated mice, potentially through stress-induced actions of substance P.

In this study, researchers found that the thyroxine receptor agonist TDM10842 accelerated the onset of anagen, a hair growth phase, in C3H mice, potentially through activation of the Wnt/beta-catenin and Hedgehog pathways, with Pclaf playing a key role in this process.

This study found that combining platelet-rich plasma therapy with minoxidil significantly improved hair growth and hair follicle cell proliferation in men with androgenetic alopecia compared to either treatment alone.

This study developed a novel liposome-based delivery system for Minoxidil and nitric oxide, which showed promising results in promoting hair regrowth in an androgenetic alopecia model by enhancing transdermal absorption, prolonging skin retention, and reducing inflammation.

This study found that oral administration of Terminalia bellirica enhanced hair growth in testosterone-suppressed conditions in both human cell and mouse models, outperforming finasteride, a current commercial hair loss treatment.

AA-PRP injections significantly promote hair growth but need better study design for clear efficacy.

This study found that collagen peptides from Mozambique tilapia significantly promoted hair regrowth and increased the proliferation of hair growth factors in vitro and in vivo, suggesting potential as supplements for hair loss prevention.

This review provides a comprehensive guide to serum-free human hair follicle organ culture methods, highlighting research opportunities, standardization efforts, and potential applications without reporting new empirical findings.

In this study, platelet-rich plasma significantly increased hair regrowth and reduced symptoms of alopecia areata compared to triamcinolone acetonide or placebo, with no observed side effects.

This study found that Oriental melon leaf extracts promoted hair growth in a mouse model and cultured human hair follicles, suggesting potential use as a treatment for hair loss.

This study found that Urticadioica L ethanol extracts enhanced hair growth and reduced catagen transition in human hair follicles in an ex vivo organ culture model.

In this study, XMU-MP-1 unexpectedly reduced cell proliferation and altered cell cycle progression in a model human hair follicle, possibly due to off-target kinase inhibition.

This case report details a rare instance of malignant proliferating trichilemmal tumour in a 60-year-old male, emphasizing the significance of histochemical and immunohistochemical markers for accurate diagnosis and differentiation from squamous cell carcinoma.

This study found that ruby laser hair removal causes microscopic epidermal damage but does not lead to cellular hyperproliferation, unlike ultraviolet-irradiated cell damage.

This study found that Geranium Sibiricum L extract may promote hair growth by increasing cell proliferation and migration while modulating cytokine expression in human dermal papilla cells under stress conditions.

In this study, oleanolic acid was found to enhance hair follicle growth and promote hair matrix cell proliferation via the Wnt/β-catenin pathway in a human hair follicle organ culture model.

This study suggests that certain electrical settings may enhance hair growth by stimulating dermal papilla cell proliferation and increasing gene expression related to hair growth in vitro and in rabbit skin.

This study found that exosomes derived from human amniotic mesenchymal stem cells enhanced stem cell proliferation and structural restoration in irradiated salivary glands of rats, with significant improvements observed by day 7, suggesting activation of the Wnt signaling pathway.
