This review discusses the basic biology of apoptosis and its relevance to skin diseases, without presenting new research findings.

This study found that dermal fibroblast cultures, especially those with higher alpha-smooth muscle actin expression, can be used to produce skin-derived precursor cells, unlike human hair follicle dermal papilla cultures.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This study identified that the enzyme CYP2B12 is skin-specific and likely plays a role in the metabolism of arachidonic acid, a key component in lipid signaling within sebaceous glands.

This study found that epidermal and fibroblast growth factors increased proliferation of human hair bulb papilla cells and root sheath fibroblasts in vitro, while hydrocortisone decreased it and minoxidil had no effect.

This study reports that a newly developed polyherbal phospholipid complex cream containing Citrus auranticum and Glycyrrhiza glabra extracts improved polyphenol retention in the skin, suggesting potential as an anti-aging cosmeceutical.

This study found that increasing a drug's lipophilicity and adding ethanol to the donor phase can enhance its delivery to the hair follicle, although the precise transport mechanism remains unclear.

This review discusses various drugs that can cause drug-induced acne, noting specific clinical and histopathologic features, but reports no new clinical findings.

This study developed a method for generating germ-like tissues called bbHFGs, which efficiently promoted hair follicle formation in mice, potentially advancing hair regenerative medicine applications.

This study observed that the ethyl acetate extract of Equisetum debile showed high activity against 5α-reductase and lipid peroxidation with no cytotoxicity on dermal papilla cells.

In this study, red ginseng extract and its ginsenosides enhanced human hair follicle cell proliferation and countered dihydrotestosterone-induced suppression, suggesting potential to promote hair growth.

This review explores the medicinal properties of Eclipta alba and its phytoconstituents and reports their potential for developing new drugs, but presents no new research results.

This study found that disrupting Stat3 in keratinocyte stem cells of mice reduced skin tumor formation by approximately 80%, suggesting Stat3's role in tumor initiation survival mechanisms.

This study found that polymeric nanoparticles may effectively deliver finasteride topically to hair follicles, potentially improving alopecia treatment with fewer side effects than oral forms.

This study found that polyamines enhance genome integrity by facilitating homologous recombination-mediated DNA repair, suggesting a novel role for polyamines beyond promoting cell growth and proliferation.

In this study, higher expression levels of aromatase and steroidogenic acute regulatory protein were correlated with increased estrogen synthesis and fewer hair follicles in human skin, suggesting a link to elastic fiber formation and hair growth.

This study presents a DNA-analytical method that can reliably identify and differentiate cashmere, fine wool, yak, and camel hair fibers in both untreated and processed samples.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This study found that mouse FLRG protein, a secreted glycoprotein, is expressed in certain tissues and plays a role distinct from follistatin during wound healing, suggesting different functions in vivo.

This study demonstrated a method for large-scale preparation of self-sorted hair follicle germs in vitro, which successfully generated hair follicles when transplanted into the skin of nude mice.

This study found that overexpression of AKR1C3 in prostate cancer cells redirected androgen metabolism towards testosterone production, which facilitated cell proliferation, potentially reducing the effectiveness of finasteride treatment.

This study found that novel androgen antagonists incorporating a carborane moiety showed anti-androgenic activity comparable to flutamide in a laboratory setting.

This study found that using 3D dermal papilla spheroid models enhances extracellular matrix production and hair follicle marker expression, providing insights into hair follicle biology and potential for drug screening.

In this study, germacrone from Curcuma aeruginosa showed anti-androgenic effects by inhibiting 5α-reductase, suggesting its potential as a lead compound for treating androgen-dependent disorders.

In this study, fibronectin coating on a low-adhesive substratum increased cell aggregation, growth, and motility, enhancing the formation of hair follicle dermal papilla spheroids.

This review discusses advances and challenges in skin tissue engineering, focusing on developing 3D constructs for functional skin substitutes, and reports no new clinical results.

This study found that LED light irradiation induced proliferation and migration of human outer root sheath cells, potentially through the stimulation of the Wnt/β-catenin and ERK signaling pathways.

This study found that a eupafolin nanoparticle delivery system improved water solubility and skin penetration, enhancing its antioxidant and anti-inflammatory effects against particulate matter-induced stress in skin cells.

This review discusses advancements in the use of microneedle arrays and nanoparticles for transdermal delivery of therapeutics, noting challenges in overcoming the skin barrier and summarizing recent clinical trial achievements in areas like cancer therapy and gene therapy.

This study observed that genetic variation in the ovine KRTAP22-1 gene is linked to increased wool yield and decreased fiber curvature in sheep, indicating its potential use in breeding programs.
