Minoxidil slows fibroblast growth and collagen production, potentially treating keloids, hypertrophic scars, and connective tissue disorders.

This study found that megestrol acetate increases the proliferation, migration, and adipogenic differentiation of adipose-derived stem cells through glucocorticoid receptor phosphorylation.

This minireview discusses a proposed model of the vitamin D receptor that explains how 1alpha,25(OH)2D3 can mediate both genomic and rapid responses through different ligand shapes and cellular locations, without presenting new research findings.

This study found that prostaglandin D2 reduced proliferation in bulge resident K15+ stem cells but not in other K15+ progenitor cells, suggesting differential impacts on hair follicle stem cell niches.

This review discusses how vitamin D and calcium signaling are essential for wound healing by activating epidermal and hair follicle stem cells, noting that deficiencies may lead to delayed or chronic wounds.

In this study, researchers aimed to investigate the effects of injecting intralesional platelet-rich plasma and vitamin D in patients with vitiligo, focusing on their potential to induce skin pigmentation. Results are not reported in the abstract.

In this study, D-OCT imaging revealed distinct structural and vascular changes in patients with frontal fibrosing alopecia, highlighting the technique's potential for diagnosing and monitoring the condition's activity.

In this study, epithelial cell-derived exosomes promoted fibroblast migration and inhibited their proliferation, suggesting a role in dermal condensate formation and hair follicle morphogenesis in cashmere goats.

In this study, Betula platyphylla extract, particularly fraction H3-2, promoted human derma papilla cell proliferation and increased expression of certain growth factors, suggesting potential benefits for hair loss prevention.

This narrative review examined skin-sparing techniques in gynecomastia surgery and found satisfactory thoracic remodeling with acceptable morbidity and reduced scarring, but acknowledged methodological differences that limit decisive conclusions.

This study found that melatonin's effect on HaCaT keratinocyte proliferation varied with concentration and incubation time, with no cytotoxic effects observed at suitable concentrations for skin treatment.

This literature review highlights the effectiveness of topical vitamin D (e.g., calcipotriol, calcitriol) in treating vitiligo, emphasizing its role in melanogenesis and as an immunomodulator, either alone or combined with topical corticosteroids, offering minimal side effects.

This study found that vitamin D regulates cholesterol metabolism and may influence prostate cancer development through mechanisms affecting prostate cell growth and sex hormone metabolism.

In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

This review explores the impact of vitamin D deficiency on the skin from a dermatological perspective, but reports no new clinical results.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This study identified WNT10A as crucial for adult epithelial cell proliferation and differentiation, suggesting β-catenin pathway activation may help address regenerative defects in WNT10A mutation patients.
