This review examines the debated link between iron deficiency and nonscarring scalp alopecia in women, offering no new clinical results but emphasizing the need for further research and well-designed trials.

This study found that Wnt10b promotes melanocyte maturation and pigmentation in the hair bulbs of mice by activating canonical Wnt signaling.

In this study, the researchers found that vitamin D and calcium signaling in keratinocytes are essential for normal skin regeneration after wounding, with deficiencies significantly delaying wound closure and re-epithelialization in mice.

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 found that ancient and modern Chinese goats share close genetic ties, originating from the Fertile Crescent, with genetic divergence influenced by China's climatic divisions.

This study found similarities in the regeneration processes of MRL mouse ears and axolotl limbs, involving G2 cell cycle arrest and nerve-dependent mitosis, but the role of p21 in axolotl limb regeneration remains uncertain.

This study found that arctiin, a compound from Arctium lappa, demonstrated protective effects against oxidative stress-induced dysfunction in human hair dermal papilla cells, suggesting potential therapeutic use for alopecia.

This review discusses the pharmacological actions of mangiferin and the potential of delivery carriers to overcome its limitations, but reports no new clinical results.

This study found that finasteride was associated with more reproductive adverse effects, including sexual dysfunction in men and fetal harm in women, compared to minoxidil in reported alopecia cases.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

This study found that DHT treatment led to reduced cell growth, increased cell death, cell cycle arrest, ROS production, and senescence in normal human dermal papilla cells, potentially mediated by altered miRNA expression.

This review discusses the role of the androgen receptor in breast cancer diagnosis and treatment, and notes a lack of new research results on its therapeutic potential.

This study reports that in MRL mice, loss of p53 does not impair ear regeneration, suggesting p21's potential role in this process may involve the Tgfb/Smad pathway.

This study found that deletion of c-Jun and JunB in mouse bulge hair follicle stem cells was sufficient to trigger psoriasis-like skin disease through thymic stromal lymphopoietin signaling.

This review highlights the pharmaceutical potential of secondary metabolites from Juniperus species, noting promising antitumor, antibacterial, and antiviral activities, but reports no new experimental findings.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.

This study identified a set of tumour-suppressive microRNAs (miRNAs), termed 'normomiRs', that are highly expressed in normal tissues but low in tumors, with miR-206 and miR-381 showing significant in vitro cancer inhibition, highlighting their potential for miRNA-replacement therapies across multiple cancer types.

In this study, cashmere goats engineered to overexpress the Tβ4 gene in hair follicles produced more cashmere, indicating that Tβ4 promotes secondary hair follicle development and enhances yield.

This study found that platelet-rich plasma may influence the proliferation of human hair dermal papilla cells by affecting gene expression related to the cell cycle.

This study found that Wnt5a suppresses β-catenin signaling, inhibiting the transition of hair follicles from the telogen to anagen phase.

This review summarizes recent progress in human hair follicle bulge cell research, particularly the characterization and isolation of these stem cells, but reports no new experimental results.

This study found that mammary resident macrophages play a key role in mammary tissue development by influencing cell division and maintaining mammary stem cell activity through the TNF-α-Cdk1/Cyclin B1 signaling pathway, highlighting their importance in the mammary stem cell niche.

This study suggests that the secretome from amniotic fluid-derived mesenchymal stem cells overexpressing Nanog could stimulate hair growth and increase follicle density, potentially aiding in alopecia treatment.

This study found that Twist1 and Tcf4 synergistically regulate the hair follicle induction ability of dermal papilla cells by forming a complex with β-catenin, enhancing their biological properties.

This study found that carvone, a plant-derived compound, decreases melanin content and inhibits melanoma cell proliferation through the cAMP pathway, suggesting potential benefits for treating melanomas and other hyperpigmentation disorders.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.

This study observed that adipose-derived stem cells modified with trichogenic factors have similar properties to dermal papilla cells and show enhanced hair regeneration potential compared to unmodified adipose-derived stem cells.

This study found that plasma rich in growth factors (PRGF) as an adjuvant to follicular unit extraction (FUE) surgery may enhance hair graft performance and reduce post-surgical inflammation and pain in hair loss patients.
