This study investigated the effects of biotin deficiency and adequacy on cell proliferation and DNA synthesis in isolated mohair follicles, particularly focusing on the incorporation of [methyl-3 H]thymidine.

This study found that loss of integrin-β4 or its ligand, laminin-α3β3ɣ2, in keratinocytes increases differentiation via delamination, and demonstrated a role for hemidesmosomes in epidermal differentiation through both mitotic and non-mitotic mechanisms, influenced by Notch signaling.

This study found that tribuloside, a flavonoid from Tribulus terrestris L., enhances melanin production in human melanocytes, zebrafish, and human skin samples without causing toxicity, potentially through inhibiting PDE to increase cAMP levels and promote the melanin biosynthesis pathway.

This study reviews various treatment options for androgenic alopecia, emphasizing the potential use of drug-loaded nanoparticles, but reports no new research results.

This review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.

This review summarizes the historical and evolving treatments for vitiligo, highlighting that combining medical and surgical approaches may enhance repigmentation outcomes, though more research and new protocols are needed.

This review discusses the mechanisms governing epidermal stem and progenitor cell differentiation, emphasizing the balance necessary for maintaining skin barrier function, and reports no new experimental findings.

In this study, hirsute women treated with cyproterone acetate and ethinyloestradiol experienced significant reductions in sebum secretion and hair growth after several months.

This study found that applying Laponite clay gels to skin wounds in mice did not speed up wound closure but significantly improved healing quality compared to phosphate-buffered saline or alginate treatments, with benefits such as enhanced re-epithelialization and hair follicle stimulation near wounds.

This study found that mouse hair follicle stem cells use symmetric cell division for maintenance and fate determination, and identified Gata6 as a crucial factor for their differentiation.

Wound healing is a complex process involving different cells and stages, leading to scar tissue formation and strength increase over time.

This article reviews new developments in hypertrichosis treatments and reports no new clinical results; permanent depilation by photothermolysis and eflornithine cream are highlighted as promising options.

This article reviews treatments for facial hypertrichosis and hirsutism and reports no new clinical findings; the authors highlight the potential of laser and pulsed flash-light systems for permanent hair removal.

In this study, the authors concluded that the TS-associated polyomavirus may disrupt Wnt/β-catenin signaling, likely contributing to abnormal hair follicle formation in trichodysplasia spinulosa.

This review evaluates methods to study stem cell division patterns, particularly in the mammary gland, and discusses genetic factors affecting division modalities and their implications for breast cancer, but reports no new results.

This study found that mammary resident macrophages regulate mammary epithelium cell division and development, with implications for maintaining mammary stem cell activity and homeostasis.

This study reports that hair regeneration in live mice involves spatially regulated stem cell divisions and requires mesenchymal interactions, observed in real-time using a novel non-invasive imaging method.

This dissertation reports that horizontal basal cells in the olfactory epithelium undergo symmetric divisions balanced by population asymmetry, which supports their renewal and differentiation during tissue homeostasis and regeneration.

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 reports that fly blood progenitors in a long-term organ culture model undergo symmetric cell divisions influenced by cell size and orientation, with infection triggering changes in cell differentiation kinetics.

This study concluded that label-retaining cells in mouse epidermis differ in their sensitivity to proliferative stimuli, influencing their division and potential transdifferentiation without consistently depleting their population.

This study demonstrates that neural stem cells in the adult vertebrate brain coordinate their division decisions using delayed local feedback mechanisms, involving Notch-mediated inhibition and dispersion effects, to maintain population homeostasis.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

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.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

This study found that the circadian clock in mouse skin regulates cell proliferation and affects sensitivity to UVB-induced DNA damage, with potential implications for understanding human skin cancer risk.

This study used two-photon microscopy to reveal that the dermal papilla is crucial for hair follicle regeneration and cannot be replaced by neighboring cells, providing new insights into stem cell behavior.

This study found that the expression of the sonic hedgehog protein is involved in wound healing texture regeneration, inhibiting skin texture after embryonic day 14 and affecting keratinocyte migration and division.
