In this study, the combination of Poly-D,L-Lactic Acid and Platelet-Rich Plasma was reported to be effective for improving wrinkle severity and skin brightness in a 45-year-old woman.

This study found significant variability in the production and use of platelet-rich plasma and related products in Brazil, highlighting the need for regulatory measures to ensure safety.

This review explores the current applications and expanding indications of platelet-rich plasma in dermatology and cosmetic dermatology, but reports no new clinical results.

This study found that using uniform poly(lactic-co-glycolic) acid microspheres to deliver insulin-like growth factor 1 stabilizes the protein and enhances its sustained delivery, supporting stem cell functions comparably to traditional methods, and showing potential for tissue and organ regeneration.

In this study, researchers optimized a method for preparing platelet-rich plasma to improve light transmittance aggregometry testing in coronary artery disease patients on clopidogrel and ticagrelor, finding distinct differences in platelet aggregation and volumes among these patients compared to healthy controls.

This study observed that hepatocyte adhesion to human hair keratin biomaterials was mediated by the hepatic ASGPR, as blocking this receptor reduced cell attachment.

This study characterized keratin-based biomaterials that self-assemble into hydrogels, demonstrating their potential to achieve hemostasis in a lethal liver injury model through specific biomaterial-receptor interactions.

This study suggests that hemoglobin α expression in the epidermis is induced by oxidative stress and may function as an antioxidant, contributing to skin barrier function.

This study identified and sequenced several keratin cDNA clones showing distinct expression patterns in mouse epithelia, with in situ hybridization highlighting differences in keratin distribution between normal and hyperproliferative tissues.

This review summarizes existing reports on placenta extract for treating liver injury and discusses its mechanisms but provides no new clinical results.

This study reports a method for fabricating biofunctional polymer fibers by using DNA-programmable cell-free protein synthesis integrated through solution blow spinning, enabling in situ protein production and potential applications in respirators, sampling swabs, and other advanced materials.

This study observed that both polynucleotides (PN HPT™) and platelet-rich plasma (PRP) improved hair density and quality in men with androgenetic alopecia, with comparable outcomes and no significant adverse events.

This study found that the orphan protein Plet-1 is expressed in specific keratinocytes of mouse hair follicles and may regulate keratinocyte interactions with inert tissues by affecting migration and adhesion.

In this study, researchers found that the pCLCA2 protein is expressed in specific areas of pig skin, but its role in skin structure or function remains unclear.

This article reviews the composition and structure of mammalian hard keratins, focusing on the filamentous and nonfilamentous protein content, and reports no new experimental results.

This study developed a bilayer material combining poly(vinyl alcohol) and bacterial cellulose with a gelatin-poly(vinyl alcohol) hydrogel, showing strong potential as a wound dressing due to its good antibacterial properties, cell viability, and sustained drug release.

This study developed a composite product from decellularized human placental connective tissue matrix and placental extract, finding that the combination showed improved biochemical and mechanical properties compared to each component alone, suggesting its potential use for treating chronic and deeper wounds.

This study found that human platelet lysate supported mesenchymal stem cell growth as effectively as fetal bovine serum, while fetal bovine serum was more effective for hepatocyte proliferation.

This study observed that PAI-2 is consistently expressed in differentiating cells of murine hair and nail, suggesting it may function as a marker of differentiation and possibly protect against premature cell death.

This study demonstrated that a newly developed polypeptide-protein hydrogel with vascularization and antibacterial properties promoted tissue regeneration and hair follicle formation in infected wound healing.

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 isolated a thermophilic bacterial strain, Bacillus cereus, from soil that produces an extracellular protease; the enzyme effectively removed non-leather structures from animal pelts and was compatible with commercial detergents.

In a study on mice, cow placenta extract showed strong antioxidant activities and reduced collagen damage, suggesting it could help delay skin aging caused by D-galactose.

This review discusses the roles of filaggrin and trichohyalin in keratinocyte differentiation and reports no new results; the authors introduce possible hybrid granules in tongue epithelia.

In this study, researchers found that size polymorphisms in certain hKAP1 genes are linked to the hKAP1.1B and hKAP1.3 genes, arising from intragenic deletions and duplications in Japanese and Caucasian populations.

In this study, the identification of a novel KAP gene in sheep, named KRTAP36-1, was associated with increased prickle factor in wool, suggesting its potential as a genetic marker for breeding purposes.

This study proposes a new method to selectively isolate keratin-associated proteins and keratin from human hair, suggesting that KAPs may support keratin fibers in hair structure.
