Study of Expression Type Iv Collagen During Mouse Kidney Ubulogenesis in Balb/C Mouse
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...
متن کاملStudy of Basement Membrane Type IV Collagen Appearance in the Brain Choroids Plexus of Mouse Fetuses
Introduction & Objective: The brain choroids plexus (BCP) plays an important role in the cerebrospinal fluid (CSF) production, but its characterization is still incomplete. Collagen type IV, is one of the most important proteins of basement membrane (BM) and extracellular matrix (ECM) of BCP. In the present study we investigated the differential period of type IV collagen in basement membrane...
متن کاملThe Role of Type IV Collagen in Developing Lens in Mouse Fetuses
Objective(s) Extracellular matrix (ECM) and basement membrane (BM) play important roles in many developmental processes during development and after birth. Among the components of the BM, collagen fibers specially type IV are the most important parts. The aim of this study was to determine the time when collagen type IV appears in the BM of lens structure during mouse embryonic development. M...
متن کاملCharacterization of an extracellular dipeptidase from Streptococcus gordonii FSS2.
PepV, a dipeptidase found in culture fluids of Streptococcus gordonii FSS2, was purified and characterized, and its gene was cloned. PepV is a monomeric metalloenzyme of approximately 55 kDa that preferentially degrades hydrophobic dipeptides. The gene encodes a polypeptide of 467 amino acids, with a theoretical molecular mass of 51,114 Da and a calculated pI of 4.8. The S. gordonii PepV gene i...
متن کاملMaternal Nexposure on Collagen Type Iv Pulmonary Changes in Mouse Offspring's
Purpose: In this study we evaluated the effect of maternal nicotine administration during pre and postnatal period on collagen IV changes in lung of mouse newborns. Materials and Methods: Female Balb/C mice were mated and finding vaginal plug was assumed as day zero of pregnancy. Pregnant mice, were divided into 2 experimental and 2 control groups. Experimental group 1, received 3 mg/kg nicotin...
