This review explores fibroblast heterogeneity in the mammalian dermis and suggests potential therapeutic applications by targeting fibroblast subtypes, but reports no new experimental results.

In this study, homozygous VDR null mutant mice exhibited nonfunctional vitamin D receptors, leading to growth abnormalities and revealing the limited physiological importance of vitamin D pathways outside the classical receptor.

This study identifies mutations in the SRD5A3 gene as a cause of a new type of congenital disorder of glycosylation, impacting mental, ophthalmologic, and cerebellar functions.

This study found that adipocytes play a crucial role in skin wound healing by facilitating fibroblast recruitment and dermal reconstruction during the healing process.

This review discusses the classification and diagnosis of pregnancy-related skin conditions and reports no new clinical findings.

This study found that overexpression of activin in transgenic mice led to enhanced granulation tissue formation after skin injury due to changes in keratinocyte proliferation and differentiation.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

In this study, researchers identified 18 genetic associations with scalp and facial hair traits in Latin Americans, including novel loci for hair greying and balding, with implications for understanding hair evolution.

This study found that psychoemotional stress disrupts hair growth in mice by terminating anagen and suggests a potential pathway for pharmacological management of stress-related hair loss in humans.

This study found that the mammalian hairless gene encodes a corepressor protein that interacts with thyroid hormone receptors, providing insights into hair loss syndromes in humans and mice.

This review discusses epidermal stem cell diversity, revealing previously unrecognized differences in stem cell populations, but reports no new experimental results; it highlights the need for further exploration of stem cell interactions and quiescence.

This study found that hypertrophic chondrocytes at the fracture callus border may convert to osteoblasts, influenced by vasculature and pluripotency gene expression.

This study found that mouse skin CD4(+) memory T cells are in equilibrium with the circulation under steady state but increase in specific clusters in response to infection or inflammation.

This study reports that mutations in the SUR2 gene are linked to Cantu syndrome, highlighting the role of KATP channels in cardiovascular health and potential new therapies.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

This study found that injecting PDGF-AA and -BB into mouse skin immediately triggered the hair growth cycle's anagen phase, suggesting potential treatment options for certain types of alopecia.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This study found that macrophages play a crucial role in nerve regeneration by regulating Schwann cell dynamics and remyelination, with Gas6 identified as a key factor in this process.

This study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

This study observed that patients receiving IL-2 immunotherapy developed a skin eruption characterized by burning and pruritus, which resolved shortly after stopping the infusion, suggesting that IL-2 mediated these effects.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This study highlights that the ACIP strongly recommends COVID-19 vaccination and booster doses for pregnant women, those breastfeeding, or trying to conceive, due to the safety of non-live vaccines in these groups and the protection they also offer to infants.

This study found that overexpression of Smad7 in transgenic mice led to severe alterations in multiple epithelial tissues, resulting in early death after birth.

This study found that carbon nanotube impurities induced immunological toxicity in mice, whereas purified nanotubes showed good biocompatibility, suggesting high-temperature thermal treatment may improve nanotube biocompatibility.

This study found that mice with a mutant CDP/Cux protein lacking the homeodomain showed severely impaired growth, high postnatal mortality, and reduced fertility, highlighting CDP/Cux's role in developmental regulation.

This review discusses the role of Wnt/β‐catenin signaling in stem and cancer stem cell maintenance and its involvement in the development and regeneration of various organs, but reports no new experimental results.

In this study, specific versican expression was observed in the anagen phase of human hair follicles, suggesting its importance in maintaining normal hair growth.

In this study, researchers identified that upon tissue injury in a mouse model, epidermal cells at the wound edge convert to an embryonic-like state with SOX11 and SOX4 playing a central role in modulating epidermal development and cell migration genes.

In this study, ACF sponges with 10% fucoidan significantly promoted wound healing and hair follicle regeneration in rats, showing improved hemostatic and antibacterial performance compared to other formulations.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.
