This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

Hair growth is cyclic and influenced mainly by local factors.

This review details the expression and diverse functions of melatonin receptors in non-neural tissues and reports no new clinical findings, emphasizing their potential as therapeutic targets across various physiological and pathological processes.

This article highlights the versatility and potential of alginate and its derivatives in tissue engineering applications, discussing their properties, modification techniques, and various uses in enhancing tissue healing, bone regeneration, and cell growth.

This article discusses the side effects of androgen deprivation therapy for nonmetastatic prostate cancer, highlighting the need for clinical trials to systematically study these effects.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

This review discusses herbal therapies for dermatologic disorders, focusing on those with scientific evidence of efficacy and common interactions, but reports no new clinical results.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

The document concludes that the exact way alcohol causes harm to fetal development is unknown, but it significantly affects nutrient transport to the fetus and a safe level of alcohol during pregnancy is not determined.

This study reviews the evolution and modifications of microneedle drug delivery systems, initially designed for percutaneous use, now expanded for targeting a variety of tissues and organs such as ocular, oral mucosal, and gastrointestinal, suggesting widespread future applicability.

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 review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.

This review highlights various methods of stem cell communication that reflect the unique organization and function of different tissues and reports no new results.

This review discusses the dual role of tissue-resident memory T cells in providing immune protection against infections and cancer and contributing to autoimmune skin disease pathology, without presenting new experimental results.

These guidelines review the management of complications and specific forms of congenital ichthyosis and report no new results; they summarize expert and evidence-based recommendations for clinicians.

Minoxidil, propranolol, and furosemide effectively control severe hypertension, but may cause sodium retention.

In this review, the researchers detailed how the p63 transcription factor influences epithelial stem cell activities such as self-renewal, differentiation, and proliferation, highlighting the role of TAp63 and ΔNp63 isoforms in both normal tissue development and cancer pathogenesis.

Scalp cooling significantly reduces hair loss in chemotherapy patients.

This study found no protective effect of topical calcipotriol on hair loss in chemotherapy patients, and the authors propose the term "atrophic telogen effluvium" for this type of hair loss.

This review discusses various skin lesions associated with endocrinologic disorders such as Cushing's syndrome and adrenal insufficiency, and it reports no new clinical results.
