Purpose: In this study specific antibody have been used for tracing type IV collagen basement membrane during renal tubules morphogenesis in mouse fetuses. Materials and Methods: 20 female Balb/C mice were selected randomly and were kept under normal condition, finding vaginal plug was assumed as day zero of pregnancy. 12 pregnant mice were scarified by cervical dislocation in one of gestationa...
Background: Collagen is a protein that constitutes a major component of connective tissue and has many applications in the medical and non-medical fields. The increase in the world population and the need for proteins have led to a special focus on seafood. Furthermore, jellyfish is a rich and renewable source of collagen. Therefore, many researchers have shown interest in collagen extraction f...
Introduction & Objective: Extra-cellular matrix and basement membrane play important roles in many developmental phenamenon during development and after birth. Among the components of the basement membrane, collagen fibers specially type IV, are the most important part of this area. As kidney is one of the target organs in diabetes mellitus and diabetic nephropathy is a major cause of end stage...
Collagen, the major extracellular matrix protein, is also a membrane protein. Two types of collagen are detected on the normal human fibroblast membrane in culture, type I collagen and a new immunologically and chemically distinct collagen, type M (membrane) collagen. Antibodies to type M collagen elicited complement-mediated cytotoxicity, which could be blocked by pretreatment of the cells wit...
Objective(s): Epidermolysis bullosa is one of the most important series of mechano-bullous heritable skin disorders which is categorized into four major types according to the layer that bullae forms within basement membrane zone. In dystrophic form of the disease, blisters are made in the sublamina densa zone, at the level of type VII collagen protein which produce anchoring fibrils. Type VII ...
combination formulations of liposomes with collagen have been previously introduced as a means of obtaining more stable and less permeable liposomes. in this study, the effect of aqueous solutions of the collagen products collapur? (col) and collapuron-dak? (cold) from henkle co., on the release rate of sodium chromate (chr) as a water-soluble model drug from stable plurilamellar vesicles (splv...
objective(s):skin extracellular matrix, which contains type i and type iii collagens, is involved in skin development. the aim of this study was to investigate type iii collagen distribution pattern as well as its changes during pre and post-natal skin morphogenesis in rats. materials and methods: ventral skins of wistar rat embryos at different stages from 10 to 20 gestational day (e10-e20) an...
background: decalcified freeze-dried bone allograft (dfdba) may have the potential to enhance bone formation around dental implants. our aim in this study was the evaluation and comparison of two types of dfdba in treatment of dehiscence defects around euroteknika ® implants in dogs. methods: in this prospective clinical trial animal study, all mandibular premolars of three iranian dogs wer...
The organization of type IV collagen in the unconventional basement membrane of the corneal endothelium (Descemet's membrane) was investigated in developing chicken embryos using anti-collagen mAbs. Both immunofluorescence histochemistry and immunoelectron microscopy were performed. In mature embryos (greater than 15 d of development), the type IV collagen of Descemet's membrane was present as ...
