Hair differentiation starts earlier than thought, involving multiple type-II keratins.

This study demonstrated that hair follicle bulge stem cells can form epidermis in a tissue-engineered skin model, highlighting the significance of K5/K17 filaments in slow-cycling stem cell subsets.

This study describes a protocol for generating hair-bearing skin organoids from human pluripotent stem cells, achieving full complexity resembling fetal skin tissue by day 130 in vitro.

This review explores the structure and development of the hair cuticle, highlighting difficulties in studying some aspects and proposing new experimental approaches, but reports no new clinical results.

This study found that genes encoding mouse high-glycine/tyrosine proteins show distinct spatial and temporal expression patterns in hair follicles, suggesting diverse protein distribution during hair growth cycles.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This study found that keratin-associated proteins form part of the developing exocuticle and a-layer in hair fiber cuticle cells, while cornified envelope proteins were absent.

This article discusses the potential role of telocytes in skin regeneration and the need to understand their interaction with platelet-rich plasma, reporting no new experimental results.

This study examined the age-related changes in the dermal structure of goat skin, providing baseline data on its histomorphology, histochemistry, and histoenzymology.

This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

This study reviews the complexities of burn-related skin complications, highlighting postburn pruritus, dyspigmentation, and the risk of malignant ulcers, while offering a framework for evidence-based management through various treatment approaches.

This review discusses the use of helmet designs in integrative medicine and transcranial photobiomodulation, highlighting new developments and potential future advancements in sensor-controlled therapy helmets, but reports no new clinical results.

In this study, adrenalectomy in black rats on a vitamin B-deficient diet restored hair growth and melanin deposition, effects reversed using adrenal cortical hormones.

This study identified two high sulfur protein genes, B2E and B2F, in rats, which are expressed in hair cortical cells during anagen and contribute to hair fiber production.

This study reports that Elvitegravir, a drug currently approved for other uses, shows potential as a neuro- and mitoprotective agent by attenuating mitochondrial damage caused by NMDA receptors in primary mouse cortical neurons.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This review summarizes recent advances in organoid technology for generating tissue models from the three germ layers and reports no new experimental results.

In this study, researchers observed that cosmetic peroxide bleaching causes oxidative damage and protein loss in human hair, not only affecting the cuticle but also deeper cortical structures, correlating with bleaching severity.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This study found that the human hairline is closely linked to several cranial, cerebral, and vascular structures, enabling precise localization of key neuroanatomical landmarks, which could assist in planning neurosurgical procedures.

In this study, remote photobiomodulation therapy to the lungs improved behavioral and neurological outcomes in rats with repeated closed-head injuries, suggesting potential preventive benefits for brain health.

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 papain/bisulfite disintegrates human hair cuticles by dissolving the endocuticle, potentially accelerated by ethanol's removal of cell membrane material.

Pollution exposure speeds up hair damage.

This study suggests that adult hair follicle stem cells can survive and potentially differentiate into neuronal cells after being transplanted in a mouse model of traumatic brain injury, indicating promise for TBI therapy.

This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.
