background: the aim of this study was to investigate the percentage of the stem cells population in human endometrial tissue sections and cultured cells at fourth passage. methods: human endometrial specimens were divided into two parts, one part for morphological studies and the other part for in vitro culture. full thickness of human normal endometrial sections and cultured endometrial cells ...
The authors present a specific aspect of the modifications of the endometrium in dysfunctional uterine hemorrhages that is the behavior of the endometrial glands. These glands are studied from a immunohistochemical point of view, regarding both the normal endometrium (inclusively at the age of two years) and the endometrium in dysfunctional uterine hemorrhages. The antigens used were VGEF and P...
An ultrasonographic evaluation of the endometrium was performed in 158 patients undergoing ovarian stimulation for an in-vitro assisted reproduction programme. Endometrial thickness was evaluated in 109 patients undergoing in-vitro fertilization (IVF) for female indications and in 49 patients undergoing intracytoplasmic sperm injection (ICSI) for male indications. The maximal endometrial thickn...
The human endometrium develops new capillaries from existing microvessels, i.e. angiogenesis, which then undergo maturation and remodeling, i.e. investment of microvessels with periendothelial mural cells, into a new vascular network during each menstrual cycle. Improper vascularization of the endometrium may cause implantation failure and infertility. Estrogen and progesterone have pivotal rol...
BACKGROUND We often see patients with a thin endometrium in ART cycles, in spite of standard and adjuvant treatments. Improving endometrial growth in patients with a thin endometrium is very difficult. Without adequate endometrial thickness these patients, likely, would not have reached embryo transfer. OBJECTIVE We planned this study to investigate the efficacy of intrauterine granulocyte co...
Calcium ions play an important role in the establishment and maintenance of pregnancy, but molecular and cellular regulatory mechanisms of calcium ion action in the uterine endometrium are not fully understood in pigs. Previously, we have shown that calcium regulatory molecules, transient receptor potential vanilloid type 5 (TRPV6) and calbindin-D9k (S100G), are expressed in the uterine endomet...
Leptin acts as a modulator of diverse reproductive functions, and recent studies have implicated involvement of leptin in the early embryo development in mammal. The aim of this study was to investigate the expression of leptin and its receptor (OB-R) in mouse oocyte and preimplantation embryo, and to examine whether leptin influenced the early embryo development. Leptin mRNA was detected in bl...
Trophinin is a membrane protein that mediates apical cell adhesion between trophoblastic cells and luminal epithelial cells of the endometrium and is implicated in the initial attachment during the process of human embryo implantation. The present study identified novel trophinin gene transcripts, which encode proteins structurally distinct from trophinin protein in the mouse. We designated the...
BACKGROUND In many studies in rodents, intraperitoneal endometriosis-like lesions are surgically induced by syngeneic or autologous transplantation of uterine tissue samples, which are sutured to the abdominal wall. However, until now the surgical techniques have not been standardized, and we address this issue here. METHODS Uterine tissue samples were transplanted to the peritoneum of C57BL/...
