This review summarizes recent discoveries of GPCRs for lysophosphatidylserine and lysophosphatidylinositol, detailing their roles as lipid mediators, but reports no new experimental results.

Stem cells are in deep skin layers, while differentiating cells are in shallow layers.

This study reports that marked, deep dermal mucin deposition in a patient with alopecia areata may indicate underlying systemic lupus erythematosus, as this feature was not prevalent in other alopecia areata cases.

This study found that enteroendocrine cells play a key role in coordinating stem cell migration towards wounds in the Drosophila intestinal epithelium, aiding tissue repair through non-canonical Wnt signaling.

This study identified a subpopulation of neural crest-derived progenitor cells in human corneal endothelial tissue from normal and Fuchs endothelial corneal dystrophy donors, which may have potential for future cell therapy development.

This laboratory study found that PI extract, along with its metabolites Ang and Mac, inhibited cell proliferation and protein expression linked to pathways involved in BPH, suggesting potential for therapeutic use, although the Ang-Mac combination showed no significant effect on apoptosis through the p53 pathway.

This study reports that in mice, CaR plays a critical role in sensing the epidermal Ca2+ gradient, influencing keratinocyte differentiation, and affecting epidermal development.

This study found that dihydrotestosterone significantly reduced the growth rate of perifollicular sheath cells but had no effect on nonfollicular fibroblasts or dermal papilla cells.

This study found that Plant Elicitor Peptides enhance root hair growth through a mechanism independent of their known receptors, with PROPEP2 playing a key role in this process by influencing gene expression related to root hair formation.

This study found that type II keratins in proliferating epithelial tissues are phosphorylated at a conserved motif during mitosis and stress, impacting keratin solubilization and reorganization.

In this study, PEG and keratin scaffolds selectively influenced protein release rates based on charge and size, suggesting their potential for targeted delivery of protein therapeutics.

This study found that using elastic nano-liposomes to deliver palmitoylethanolamide improved its transdermal delivery and enhanced its skincare effects, with minimal cytotoxicity and no allergic reactions observed.

This study found cell-specific variations in POMC mRNA and peptide expression in murine skin, suggesting that PC1 and PC2 convertases contribute to differential POMC processing.

This study found that the natural alkaloid cepharanthine effectively inhibited porcine epidemic diarrhea virus infection in newborn piglets.

This study established a protocol to isolate and culture dermal papilla cells from human hair follicles, suggesting alkaline phosphatase activity as a key marker to differentiate them from human fibroblasts.

This study provides evidence that human sweat gland myoepithelial cells contain stem cells capable of self-renewal and differentiating into sweat gland luminal cells.

This study identified two cell surface markers, FAP and CD90, that distinguish between papillary and reticular fibroblasts in human skin, suggesting distinct functions and distribution in dermal layers.

This study identified two novel genes, pmg-1 and pmg-2, expressed in various skin and gland tissues and potentially involved in the differentiation of epithelial cells in epidermal appendages.

This review suggests that telocytes in male reproductive organs help organize tissue structure and paracrine factors, impacting organ development and pathology, but more research is needed on their molecular pathways.

This study found that P311 triggers transdifferentiation of epidermal stem cells into myofibroblast-like cells via TGFβ1/Smad signaling during wound healing.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.

This study found that platelet-derived extracellular vesicles from apheresis platelets may effectively activate dermal papilla cells and promote hair follicle growth in a mouse model of hair regeneration.

This study found that loss of Apc due to K14-cre-mediated gene recombination in mice led to aberrant growth in ectodermally derived squamous epithelia, implicating its critical role in specifying epithelial cell fates during embryonic development.

This review discusses newly identified non-Edg family lysophosphatidic acid receptors, detailing their roles in vascular development, platelet activation, and hair growth, and reports no clinical results.

This study identified 15 Iranian patients with PLEC variants linked to various plectinopathies and highlighted a novel association between a homozygous nonsense variant in PLEC and a rare combination of disorders including EB pruriginosa, muscular dystrophy, and congenital myasthenic syndrome.

This study found that BMP2 increased PTEN expression and induced autophagy, promoting hair follicle stem cell differentiation in both in vitro models and a mouse wound model.

In this study, partially purified apple polyphenols were found to inhibit preadipocyte differentiation in mouse cells by reducing GPDH activity and triglyceride accumulation.

This study found that nestin-expressing unipotent progenitor cells capable of differentiating into outer root sheath keratinocytes are present during hair follicle development and in adult hair follicles.

This study found that TPA induces apoptosis in pig renal epithelial cells by affecting cell cycle proteins, and activated ras can prevent this process.

This study reports a case of cystic panfolliculoma, highlighting the role of epithelial-mesenchymal interactions in its pathogenesis and explaining its histological resemblance to trichofolliculoma.
