This review elaborates on the concept of cutaneous mosaicism and its link to acneiform conditions, but it reports no new clinical results.

This study introduced a bioengineered model that simulates acne's microenvironment in mice, enabling the exploration of host and P. acnes interactions and presenting a novel platform for anti-acne drug and vaccine screening.

In this laboratory study, Camellia japonica fruit shell extract showed potential to mitigate hair loss by promoting hair cell growth and reducing harmful effects of DHT and oxidative stress.

In this case report, a rare association between Cushing's syndrome caused by ectopic ACTH from cervical cancer is documented, highlighting the diagnostic challenges, treatment complexity, and high morbidity and mortality, with the patient succumbing to septic shock post-surgery.

This study found that topically applied Chinese black tea extract, when fermented and combined with capsaicin, significantly promoted hair growth in mice, potentially involving estrogen receptor interactions.

This study found that the protein CCN2 in dermal papilla cells is a physiologically relevant suppressor of hair follicle formation by destabilizing β-catenin, which may help maintain stem cell quiescence.

In this study, researchers developed a pemphigus mouse model expressing anti-Desmocollin 3 antibodies and found it mimicked atypical pemphigus with distinct pathological features compared to the standard Desmoglein 3 model.

This study found that a conditioned medium from human umbilical cord mesenchymal stem cells cultured in a gelatin sponge significantly enhanced hair growth and promoted skin angiogenesis in a mouse model, more effectively than a monolayer culture.

This study found that Centipeda minima extract promotes hair growth by activating Wnt/β-catenin, ERK, and JNK signaling pathways in human hair follicle dermal papilla cells.

Mouse Scube3 affects teeth, tongue, vibrissae, and eye development, but not facial structure or limb growth.

This review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

This study observed that in adult mice, a cell-autonomous size control mechanism involving the RB pathway determines the timing of S phase entry in epidermal stem cells based on their size, while external microenvironment factors influence growth rates but not this intrinsic coupling.

The researchers reported that conditioned media from deer antler mesenchymal stem cells may enhance hair and skin regeneration by modulating cellular responses through secretory vesicles.

In this study, knockout of B-raf and C-raf genes in mice showed they are not needed for early melanocyte development, but are crucial for maintaining melanocyte stem cells, as evidenced by hair graying due to stem cell depletion.

This article discusses the development of an interactive workbook by OCCAM to help cancer patients communicate their use of complementary and alternative medicine with healthcare providers and reports no clinical results.

This study found that loss of the Pten gene in Lgr5+ hair follicle stem cells promoted squamous cell carcinoma formation through the Akt/β-catenin signaling pathway.

This study provides conclusive evidence of exogenous calcium fatty acid deposits forming between the cuticle layers in hair, affecting its optical and mechanical properties.

This article discusses the potential of mesenchymal stem cell-derived exosomes (MSCs-exosomes) in regenerative medicine, highlighting their beneficial effects like anti-inflammatory and tissue regeneration properties, and noting challenges such as exosome isolation and safety evaluation that need addressing.

This study reveals that CSPG4-positive basal cell keratinocytes show distinct global gene expression from CSPG4-negative cells, despite similar colony-forming efficiency.

This study developed a method using UHPLC-MS/MS and MSPE to detect trace amounts of sex hormones in cosmetics, finding progestins and estrogens in some products, and performed a preliminary safety evaluation for residual progesterone in hair loss prevention cosmetics.

This study reported that exosomes derived from human amniotic mesenchymal stem cells (hAMSC-exo) accelerated hair growth in androgenetic alopecia mice by enhancing signals between hair follicle cells and improving cellular environments, particularly protecting against dihydrotestosterone-induced damage via Wnt/β-catenin signaling.

This study reports a case of a child with congenital skin fragility, alopecia, and cardiomyopathy due to compound heterozygous mutations in the DSP gene causing desmoplakin deficiency.

This study reports that tissue-engineered skin using ES cell-derived epidermal stem cells and collagen sponge successfully healed full thickness skin defects in mice, forming epidermis and structures resembling glands and hair follicles.

This study found that photobiomodulation-irradiated conditioned medium from human adipose-derived stromal cells enhanced hair growth in mice, suggesting its potential as a treatment for hair loss by increasing growth factor secretion.

This study found that in a mouse model, betamethasone dipropionate reduced epidermal thickness while fish oil unexpectedly increased it, validating optical coherence tomography as an effective measurement tool.

In this study, a biofunctional hydrogel incorporating mesenchymal stem cell-derived small extracellular vesicles promoted wound healing and reduced scar tissue formation by modulating the immune response in a mouse skin injury model.

This review discusses the potential of mesenchymal stem cells from human periapical cysts for regenerative medicine, highlighting their easy accessibility and valuable regenerative properties, but reports no new clinical findings.

This review discusses the role of Hedgehog signaling in basal cell carcinoma development and highlights genetic mouse models and potential targeted therapies, but reports no new clinical results.
