Purpose: Study of the effects of lead on the ultrastructure of uterine endometrium. Materials and Methods: In this study 40 female Balb/c mice with the age of one week were divided into two control and experimental groups. The experimental group were daily injected intraperitoneally 75 microgram per gram of lead nitrate dissolved in physiological serum for two weeks. The mice of control group w...
Mechanisms of stromal-epithelial crosstalk are essential for Prostate cancer (PCa) tumorigenesis and progression. Peripheral zone of the prostate gland possesses a stronger inclination for PCa than transition zone. We previously found a variety of genes that differently expressed among different prostate stromal cells, including LIM domain only 2 (LMO2) which highly expressed in peripheral zone...
We have previously described the isolation of separate populations of CD34+, CD38- stromal and hematopoietic progenitors cells within fetal bone marrow. The CD34+, CD38-, CD50+, HLA-DR+ population contained the majority of primitive hematopoietic progenitor cells, whereas stromal progenitors were contained within the CD34+, CD38-, CD50-, HLA-DR- population. In this study, we compared the freque...
In recent years, there has been a shift toward tissue-engineering strategies using stem cells for plastic and reconstructive surgical procedures. Therefore, it is important to develop safe and reproducible protocols for the extraction of adipose-derived stromal cells (ASCs) to allow cells to be stored in liquid nitrogen for future needs. The aspirated liposuction obtained from healthy donors we...
Background: Recent reports demonstrated that intravenous route as a minimally invasive method, similar to direct injection, is suitable for bone marrow stromal cell (BMSC) transplantation. In this study, we made a comparison of intraspinal and intravenous route of BMSC administration to repair injured spinal cord tissue. Methods: Six groups of adult female rats were used in this study. Laminect...
Objective Chemotherapy may damage ovaries. L-carnitine (LC) as a type of flavonoid antioxidants and bone marrow stromal cells (BMSCs) as a type of mesenchymal stem cells may recover damaged ovaries. It seems that LC has favorable effects on differentiation, increasing lifespan and decreasing apoptosis in BMSCs. The aim of this study was to investigate the effects of co-administration of BMSCs a...
Introduction: Fibroepithelial stromal polyp (FESP) of the female lower genital tract is a rare benign lesion characterized by polypoid proliferation of stroma, covered by a benign squamous epithelium in the vulvovaginal region. These hormone-sensitive lesions usually occur in young to middle-aged women. The lesions are typically no larger than 5 cm in diameter and are found randomly during rout...
objective: non:union: is defined as a minimum of 9 months since injury without any visible progressive signs of healing for 3 months. recent literature has shown that the application of mesenchymal stromal cells is safe, in vitro and in vivo, for treating long bone non:union:. the present study was performed to investigate the safety of mesenchymal stromal cell (msc) implantation in combination...
B-lymphopoiesis decreases with age. We studied how aging affects bone marrow stromal cells, because they provide the growth factors and cell contacts required for B-lymphopoiesis. No differences were noted in the cell-surface phenotype of young and old primary-cultured stromal cells. Fluorescence-activated cell sorter-purified stromal cells from old mice were deficient in the ability to support...
BACKGROUND Functioning stromal cells are sometimes seen in primary and metastatic ovarian neoplasms. However, the cytologic features of functioning stromal cells have been described only rarely. CASE A 19-year-old woman had an alpha-fetoprotein-producing ovarian yolk sac tumor with functioning stroma. Her preoperative serum testosterone level was elevated. Imprint cytology showed that the fun...
