In this study, researchers found that transgenic expression of the Hairless gene in keratinocytes can restore hair follicle regeneration in Hr-deficient mice by repressing Wise, a modulator of Wnt signaling.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

This study found that while molecular hair structures were nearly identical across individuals, genetic factors seem to influence specific lipid compositions, as seen in identical-patterned hair from parent-child pairs and identical twins, but not fraternal twins.

This review examines the role of Hairless, a nuclear receptor corepressor, in regulating Wnt signaling during hair cycling and reports no new clinical results.

This study introduced a new technique, 2Phatal, enabling precise apoptotic cell ablation in living animals, revealing unique cell-type differences in apoptosis-related dynamics.

This study found that lower salmon availability was associated with higher stress hormone levels in grizzly and black bears, influencing their physiological responses and competitive behaviors.

This review discusses the potential of adipose-derived tissue components like nanofat and stem cells for aesthetic rejuvenation, covering their use in hair growth, scar reduction, and more, without reporting new clinical results.

This narrative review evaluates evidence that regional hypothermia can reduce oral, hair, eye, and nail complications from chemotherapy, but highlights the need for more research to address study limitations.

This study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.

This review discusses the potential of biomimetic synthetic vesicles to advance precision diagnostics and medicine by combining the beneficial properties of naturally occurring extracellular vesicles and synthetic nanoparticles, although no new clinical results are reported.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

In this study, prolonged systemic administration of 17β-estradiol in castrated male mice delayed wound healing by inhibiting re-epithelialization and reducing collagen accumulation, with estrogen receptor-α likely mediating this effect.

Minoxidil improves blood flow and vessel flexibility, potentially helping with vascular stiffness.

This review discusses the use of platelet-rich plasma for facial rejuvenation, acne scarring, and androgenic alopecia and reports positive outcomes but emphasizes the need for standardized preparation and application methods.

This case report describes fetal malformations and placental abnormalities in a pregnant woman who applied minoxidil topically, suggesting potential risks of its use during pregnancy.

This study found that glutathione deficiency affects lateral root and root hair responses to indole butyric acid in plants, but not to indole acetic acid, indicating its role in auxin pathway regulation.

Developing human skin has immune cells with memory-like features.

This study reports that compound heterozygous loss-of-function mutations in the HEPHL1 gene in a child were associated with abnormal hair and cognitive issues, linking altered ferroxidase activity to hair disorders.

This study found that the binding and release of BMP-2 from kerateine biomaterials are significantly influenced by pH and salt concentration, highlighting the potential for developing improved bone repair systems.

This review explores the similarities between wound healing, palatogenesis, and orofacial clefting, suggesting these processes share common pathways and genetic regulatory mechanisms, but reports no new experimental results.

In this study, researchers found that the human hair follicle microbiota vary by anatomical compartment and donor age, with specific microbes like S. epidermidis potentially influencing hair follicle functions, which suggests new avenues for therapeutic targeting.

This study found that despite carrying an activating Hras mutation, hair follicle stem cells integrate into normal skin without causing tumors, unlike similar mutations in the epidermis, suggesting unique tumor-suppressing mechanisms in hair follicles.

This study found that the development of Merkel cell carcinoma from hair follicles in mice can be driven by in vivo reprogramming with ATOH1 and relies on p53 loss for progression.

This article reviews the use of the transtemporal approach for midface and lower eyelid-cheek junction rejuvenation, detailing surgical techniques, post-operative care, and potential complications, but reports no new clinical results.

This study found that the pH dependency of rat steroid 5α-reductase type II isozyme significantly affects its kinetic properties, including Vmax and Km, suggesting past discrepancies in literature may arise from these pH variances during assays.

This review discusses the role of telomere length dynamics in hair follicle biology and reports no new clinical findings, emphasizing the need for further research in humans.

This review discusses the unique dermatologic needs and conditions affecting women of color, noting specific skin and hair conditions but reports no clinical results.

This study reports that actively proliferating Lgr5+ stem cells in hair follicles do not appear to drive tumor formation in experimental skin carcinogenesis.

In this study, researchers analyzed spaceflight data from various sources and found that skin issues during spaceflight are linked to DNA damage, mitochondrial dysregulation, and gene alterations, while also highlighting the skin's adaptability post-flight.

This study shows that NIPP1 deficiency in mouse epidermis leads to hyperproliferation, hair loss, and chronic skin inflammation, which can be partially alleviated by dexamethasone treatment.
