This study found that applying topical imiquimod during mid and late telogen in mice activates hair follicle stem cells and influences immune cell infiltration, promoting hair cycle entry independently of Wnt signaling.

This study found that hoof progenitor cells from fresh equine tissue have multilineage differentiation capabilities, offering insights for future progenitor cell-based hoof and dermal-epidermal tissue engineering.

This study found that certain metabolites from the plants Bidens pilosa, Calophyllum inophyllum, and Fagraea berteroana may support hair follicle growth by promoting dermal papilla cell proliferation, supporting their traditional use in hair care.

This study found that, despite the unchanged total level of 18-MEA, deletion of the Sox21 gene disrupts its attachment to the hair cuticle, increases cholesterol sulphate levels, and differentially affects ceramide composition.

This study found that inhibiting autophagy in mouse preputial glands alters lipid metabolism, delays aging-related duct changes, and reduces pheromone production, indicating autophagy's critical role in gland homeostasis and cell breakdown during secretion.

This study found that finasteride treatment in male rats has lasting effects on depressive-like behavior, hippocampal neurogenesis, neuroinflammation, and gut microbiota composition even one month after discontinuation.

This review paper critically evaluates the pharmacological and toxicological effects of Ziziphus mauritiana, a plant with traditional medicinal use, highlighting its anxiolytic, antioxidant, antimicrobial, anti-cancer, anti-diabetic, and anti-ulcer properties attributed to its rich phytochemical composition.

In this study, the researchers found that the chemical composition and color of the brown seaweed *Saccharina latissima* varied significantly depending on the harvesting period, site, and cultivation method, suggesting that environmental conditions play a key role in these variations.

This study found that extracts from Geranium pyrenaicum show promising antioxidant, enzyme inhibitory, and antiviral activities, particularly the methanolic extract's antiviral activity against HSV-1.

This study found that KrasG12D mutant cells are typically cleared from adult pancreas tissues through mechanisms involving the EphA2 receptor, suggesting its role as a tumor suppressor in pancreatic cancer.

This study found that in mice, deleting the keratin 10 gene enhances sebocyte differentiation and increases secretion of sebum and certain lipids without affecting proliferation-associated keratins.

This review highlights that iPSC-derived artificial platelets offer a promising alternative to platelet-rich plasma for regenerative medicine, with standardized manufacturing and reproducible pharmacological properties, addressing variability issues associated with donor-derived platelets and showing therapeutic potential in preclinical models of osteoarthritis.

This article reviews the roles and synthesis of essential long-chain fatty acids in the body and reports no new research findings; it emphasizes the importance of dietary sources for these lipids.

This narrative review discusses the structure and functions of the skin, focusing on its barrier role, self-repair, thermoregulation, and immune functions, and reports no new experimental results.

This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

Understanding skin structure and development helps diagnose and treat skin disorders.

This review highlights how disruptions in the host microbiome can worsen inflammation and infection-related pathology, while it remains unclear exactly how the microbiome helps resolve such inflammation, potentially impacting future treatments for infection-induced inflammatory diseases.

This study found that soluble CD83 (sCD83) accelerated chronic and hard-to-heal wound healing and improved inflammatory and pro-resolving cytokine profiles, suggesting potential for therapeutic use.

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 discusses the development and future prospects of biomaterials for in situ tissue regeneration but reports no new research results; it underscores the importance of biomaterials in addressing tissue defects.

Ceramide Synthase 4 is crucial for healthy skin barrier function.

In this study, researchers used 3D bioprinting to successfully create engineered skin tissues with hair follicle-like structures, potentially enhancing skin grafts and safety testing for chemical compounds by more closely mimicking natural skin complexity.

mTORC2 is crucial for healthy skin barrier by regulating lipids and filaggrin.

This study found that an injectable composite hydrogel containing cerium bioactive glass improved wound healing in diabetic rats by promoting angiogenesis and offering antibacterial properties, suggesting its potential for enhancing diabetic foot wound repair.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This review discusses how studying regenerative biology in certain mammalian models could enhance our understanding of complex tissue regeneration, but it reports no new clinical findings.

In this study, feeding Gymnocypris eckloni with Flammulina velutipes residues enhanced foregut morphology and beneficially altered gut microbiota, highlighting potential improvements in intestinal health for aquaculture use.

In this study, inducible whole-body Acly-knockout mice revealed that ACLY is essential for skin homeostasis, as its deficiency led to increased sebum production and skin abnormalities, indicating a vital role for cytosolic acetyl-CoA synthesis in preserving skin barrier integrity and systemic lipid regulation.

In this study, researchers observed that graded calorie restriction in mice led to changes in stable isotope ratios and elemental content in bone collagen and hair keratin, potentially indicating intensified mobilization of endogenous proteins and altered bone collagen structure with increased dietary stress.

In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.
