20 / 1000+ resultsresearch A Novel Marker of Tissue Junctions, Collagen XXII
This study identified collagen XXII as a novel extracellular matrix protein specifically present at tissue junctions, where it functions as a cell adhesion ligand for skin epithelial cells and fibroblasts.
research Role of Macrophages in Collagen Resorption During Hair Growth Cycle
Macrophages help break down collagen around hair follicles during hair growth.
research Ontogenetic Transition in Fetal Wound Transforming Growth Factor-Beta Regulation Correlates with Collagen Organization
This study observed that the ontogenetic transition from scarless repair in early fetal rat wounds to scar-forming repair in late gestation is associated with differential TGF-β ligand and receptor expression patterns.
research Life Before and Beyond Blistering: The Role of Collagen XVII in Epidermal Physiology
This review explores the physiological roles of collagen XVII in the epidermis, its involvement in stem cell maintenance, and its connections with signaling pathways, but it reports no new results.
research The 800-nm Diode Laser Irradiation Induces Skin Collagen Synthesis by Stimulating TGF-β/Smad Signaling Pathway
This study concluded that the 800-nm diode laser is effective in enhancing skin structure and collagen expression via the TGF-β/Smad pathway, suggesting potential for non-ablative rejuvenation.
research Growth Factors Specifically Alter Hair Follicle Cell Proliferation and Collagenolytic Activity Alone or in Combination
Growth factors can either promote or inhibit hair follicle cell growth and collagen breakdown.
research Epithelial Differentiation of Human Adipose-Derived Stem Cells Undergoing Three-Dimensional Cultivation with Collagen Sponge Scaffold via an Indirect Co-Culture Strategy
This study found that human adipose-derived stem cells co-cultured on a collagen sponge scaffold showed increased differentiation into keratinocytes, suggesting potential for improved skin wound healing.
research Collagen and Fractionated Platelet-Rich Plasma Scaffold for Dermal Regeneration
This study found that hydrogels supplemented with fractionated platelet-rich plasma recruited more dermal-derived stem cells and accelerated healing, leading to hair growth and skin regeneration in rats.
research Basement Membrane Zone Remodeling During Appendageal Development in Human Fetal Skin: The Absence of Type VII Collagen Is Associated with Gelatinase-A (MMP2) Activity
This study found that Gelatinase A activity is linked to the absence of type VII collagen during human fetal skin development, indicating its role in remodeling the basement membrane zone.
research Minoxidil Exerts Different Inhibitory Effects on Gene Expression of Lysyl Hydroxylase 1, 2, and 3: Implications for Collagen Cross-Linking and Treatment of Fibrosis
Minoxidil affects collagen-related genes, potentially helping treat fibrosis.
research The Distributions of Type IV Collagen Alpha Chains in Basement Membranes of Human Epidermis and Skin Appendages
This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.
research Biorevitalizing Effect of a Novel Facial Serum Containing Apple Stem Cell Extract, Pro-Collagen Lipopeptide, Creatine, and Urea on Skin Aging Signs
In this study, a new apple stem cell extract serum significantly improved signs of skin aging and enhanced cell metabolism in human senescent fibroblasts, showing visible effects after one week of use.
research Co-Culture of Human Hair Follicles and Dermal Papillae in a Collagen Matrix
This study found that dermal papilla cells in culture may enhance and attract follicular epithelial cell growth, suggesting their pivotal role in hair and follicle development.
research Effect of Hyaluronic Acid and Poly-L-Lactic Acid Dermal Fillers on Collagen Synthesis: An In Vitro and In Vivo Study
This research found that hyaluronic acid increased cell proliferation and type I collagen more effectively than poly-L-lactic acid in both human fibroblast cultures and rat dermis.
research Lack of Collagen VI Promotes Wound-Induced Hair Growth
This study found that collagen VI influences hair follicle growth and wound-induced regrowth by activating the Wnt/β-catenin signaling pathway in mice, suggesting potential therapeutic targets for hair loss.
research Measuring Collagen Injury Depth for Burn Severity Determination Using Polarization Sensitive Optical Coherence Tomography
This study presents a method using polarization-sensitive optical coherence tomography to accurately assess the depth of burn wound damage in the dermal collagen matrix, potentially improving diagnosis beyond traditional visual methods.
research Collagen/Chitosan Gels Cross-Linked with Genipin for Wound Healing in Mice with Induced Diabetes
In a study using a mouse model of diabetes, chitosan-based hydrogels increased healing markers and improved wound closure and tissue repair compared to untreated wounds, but human efficacy needs further validation.
research Proliferation and Differentiation of Organoid Hair Follicle Cells Co-Cultured with Fat Cells in Collagen Gel Matrix Culture
This study found that in a rat skin model, fat cells inhibited the proliferation of organoid hair follicle cells and fibroblasts but may have accelerated hair follicle cell differentiation.
research Epidermal Stem Cells Cultured on Collagen-Modified Chitin Membrane Induce In Situ Tissue Regeneration of Full-Thickness Skin Defects in Mice
This study reports that transplantation of an ESCs-collagen-chitin biomimetic membrane leads to successful in situ skin regeneration, including hair follicle cell proliferation and formation of dermatoglyphs, in nude mice with full-thickness skin defects.
