the importance of extra cellular matrix (ecm) in development and function of different cells has been reported but little is known about its role in human endometrial epithelial cells. the aim of the present study was to examine effects of artificial ecm (matrigel) and progesterone on the function and morphology of human endometrial epithelial cells in vitro. methods: endometrial samples were r...
Background: Ceftriaxone is an antibiotic used for treating respiratory,skin,bone and kidney infections. Our purpose was investigating effect of ceftriaxone on testicular tissue. Materials and Methods: 40 mice with 6 weeks old were used in this study. The mice randomly were divided into 2 groups, control- sham and test groups. The test group was subdivided to IP1 and IP2 which received Ceftriaxo...
Dynamic and reciprocal epithelial-mesenchymal interactions are critical for the normal morphogenesis and maintenance of epithelia. Epimorphin has been identified as a unique molecule expressed by mesenchymal cells and myofibroblasts and has putative morphogenetic effects in multiple epithelial tissues, including intestine, skin, mammary gland, lung, gallbladder, and liver. To define the in vivo...
Abstract Diabetes mellitus (DM) is one of the greatest public health threats in modern societies. Although during a few years it was suggested that DM had no significant effect in male reproductive function, this view has been challenged in recent years. From a clinical perspective, the evaluation of semen parameters, as well as spermatozoa deoxyribonucleic acid (DNA) integrity, are often st...
Purpose: The objective for this study is to investigate the morphology and ultrastructure of mouse endometrial epithelial cell monolayer cultured on matrigel in dual-chambered system as an in vitro mouse endometrial epithelial cell culture model that mimics structural and functional properties of the endometrial epithelium in vivo. Materials and Methods: Mouse endometrial epithelial cells were...
Cytological changes of the epithelial cells according to the developmenatal phases of the seminal vesicle related to the spermatogenic stages in the testicular lobules during spermagenesis in male Neptunea (Barbitonia) cumingii (Gastropoda: Buccinidae) were investigated monthly by electron microscopical and histological observations. N. (B) cumingii is dioecious, and an internal fertilization s...
Background and purpose: One of the recent techniques for increasing the output of cryopreservation is using different scaffolds in long-term preservation of stem cells for cell therapy. Undesirable differentiation and decrease in the number of viable cells are two major problems in this process. In order to overcome these problems, in this study the human amniotic epithelial cells were cryopres...
Background: Endometriosis is the presence of a functional endometrial tissue outside the uterine cavity and defines as cancer like model. Noscapine is a safe cough suppressant which has been introduced as cancer suppressor. The aim of this study was to investigate the in vitro effect of noscapine on human endometriotic epithelial cells. Materials and Methods: Human endometriotic biopsies (n=7) ...
Background & Aims: Increase of blood glucose levels leads to structural and functional changes in reproductive system. This investigation was conducted to evaluate the effects of diabetes on the structure and function of testicular tissue focusing on the ultrastructure of the epithelium of seminiferous tubules. Materials & Methods: Diabetes was induced in adult male rats by single intraperiton...
Abstract Background: The amniotic membrane has gained much attention in regenerative medicine as a precious cell source. Recently, reparation of three dimensional matrices (scaffold) with appropriate specificity for cell culture, which depends on cell type, has been the subject of many studies .This study aimed to design optimal three-dimensional matrices in order to utilize amniotic epithel...
