Mouse leukemia virus growth in mouse cells contaminated with Mycoplasma.

Elimination of Mycoplasma Contamination from Infected Human Hepatocyte C3A Cells by Intraperitoneal Injection in BALB/c Mice

Background/Aims: The use of antibiotics to eliminate Mycoplasma contamination has some serious limitations. Mycoplasma contamination can be eliminated by intraperitoneal injection of BALB/c mice with contaminated cells combined with screening monoclonal cells. However, in vivo passage in mice after injection with contaminated cells requires a long duration (20-54 days). Furthermore, it is impor...

Effect of daunorubicin drug with and without cimetidine on the nucleated cells of bone marrow of balb/c mouse

Introduction: Hematopoiesis is an on going process mammalian marrow system. A few cells from the nucleated cells of bone marrow are hematopoietic cells which include primary stem cells, precursor cells and progenitor cells. Primary stem cells and progenitor cells are able to produce colonies in culture medium (CFU-C) and irradiated mouse spleen (CFU-S). A hematopoietic cell is alive and act...

Improvement of Expression of α6 and β1 Integrins by the Co-culture of Adult Mouse Spermatogonial Stem Cells with SIM Mouse Embryonic Fibroblast Cells (STO) and Growth Factors

The Effects of Different Concentrations of Leukemia Inhibitory Factor on the Development of Isolated Preantral Follicles from Fresh and Vitrified Mouse Ovaries

Background: Leukemia inhibitory factor (LIF) is a pleiotropic cytokine of interleukin-6 family with a remarkable range of biological actions such as proliferative effects on the granulosa and theca cells. The aim of this study was to evaluate the effects of LIF on the growth and maturation of mouse fresh and vitrified preantral follicles, an in vitro model was developed. Methods: The ovaries of...

Effects of Leukemia Inhibitory Factor on gp130 Expression and Rate of Metaphase II Development during in vitro maturation of mouse oocyte

Background: Leukemia inhibitory factor (LIF) is a 45-56 kDa glycoprotein that has an important role in proliferation and embryo implantation. Its effect on oocyte maturation and how to exert the function remained to be elucidated. Methods: Immature mice superovulated with human menopausal gonadotropin and germinal vesicle (GV) oocytes were obtained from ovary 48 hours after. GV oocytes were cul...
