human bone marrow derived mesenchymal stem cells (hbmscs) have the potential to differentiate into cells such as adipocyte, osteocyte, hepatocyte and endothelial cells. in this study, the differentiation of hbmscs into endothelial like-cells was induced in presence of vascular endothelial growth factor (vegf) and insulin-like growth factor (igf-1). the differentiated endothelial cells were exam...

BACKGROUND Human endometrium has immense regenerative capacity, growing ~5 mm in 7 days every month. We have previously identified a small population of colony-forming endometrial stromal cells which we hypothesize are mesenchymal stem cells (MSC). The aim of this study was to determine if the co-expression of two perivascular cell markers, CD146 and platelet-derived growth factor-receptor beta...

Retrograde flow of menstrual blood cells during menstruation is considered as the dominant theory for the development of endometriosis. Moreover, current evidence suggests that endometrial-derived stem cells are key players in the pathogenesis of endometriosis. In particular, endometrial stromal stem cells have been suggested to be involved in the pathogenesis of this disease. Here, we aimed to...

Abstract Asherman syndrome (AS) refers to the loss of endometrial stem cells and matrix hyperplasia caused by basal layer injury. Its common clinical manifestations include narrowing uterine cavity, reduction in menstrual volume, abdominal pain, amenorrhea, infertility. According cause AS, treatment includes a mechanical barrier functional recovery. Because recovery endometrium depends on regen...

high-dose chemotherapy and autologous stem cell transplantation (sct) have become an effective care for many patients with hematological malignancies. harvesting the stem cells is one the most important parts of sct. the two most commonly used mobilization regimens are the use of granulocyte colony-stimulating factor (g-csf) or g-csf plus chemotherapy. however, about 10-30% of patients are unab...

introduction: this review reports the current results of hematopoietic stem cell transplantation (hsct) in patients who had received transplantation in the hematology-oncology and sct research center, tehran, iran. methods: in iran, from 1991 through 2010, a total of 3170 hematopoietic stem cell transplantation have been carried out. the male/female patient ratio was 1909/1261 with a median age...

Giant cell carcinoma of the endometrium is a rare and an aggressive tumor that should be distinguished from other endometrial tumors with a prominent giant cell component, including trophoblastic tumors, certain primary sarcomas, and malignant mixed müllerian tumors. At present, cumulative data on this rare histological variant is limited and the prognostic significance of the presence and the ...

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: cell-based treatments are currently being actively received great attention among scientists and clinicians for a variety of diseases as well as diabetes .the aim of this study was to investigate the effect of allotransplantation of fetal liver-derived cell suspension in patients with type 1 diabetes. methods: patients with type 1 diabetes (n=16) aged 6-30 years-old were included in...

The endometrium is a highly regenerative tissue that plays a crucial role in implantation. We examined the clonal constitution of glandular cells as well as the luminal epithelium of this unique tissue. Using collagenase-based digestion techniques with microscopic manipulation, we isolated individual human endometrial glands and examined their clonality using a polymerase chain reaction-based a...
