Background: The present study was designed to evaluate the homing potential of mouse embryonic stem cells (ESC) treated with erythropoietin (EPO) in hematopoietic organs such as spleen and liver after transplantation using morphological and immuno-histochemical techniques. Methods: Day-four embryoid body (EB)-derived cells were dissociated and re-plated in medium in the presence and absence of ...

objective: in this investigation murine embryonic stem (es) cells were differentiated into endothelial cells. materials and methods: murine es cells (cce cell line) exposed to alpha-mem medium containing 10% fbs for 4 days. then obtained flk-1 (flk-1: vascular endothelial growth factor receptor 2) positive cells were cultuted in endothelial growth medium-2 (egm-2) until the last day of experime...

perivascular epithelioid cell tumor (pecoma) is composed of hmb45+ epithelioid cells with clear to granular cytoplasm and perivascular distribution. we describe a uterine pecoma in a 33 years old woman where tumor cells were positive for hmb45 but negative for epithelial markers and negative or positive for smooth muscles markers.

BACKGROUND Chromatoid bodies (CBs) are characteristic spermatid organelles, which were suggested to function in RNA storage and small RNA processing but whose functions remain largely unknown. CB components include Mili, Miwi, and Tudor domain proteins such as Tdrd6, whose contribution to CB structure and function is elusive. RESULTS We determined gametogenesis stage- and male-specific expres...

Objective Diazinon is an organophosphate pesticide and today this pesticide is mostly used in agriculture. In this study, we analyzed the effects of diazinon and vitamin E on apoptosis and the proliferation of germ cells in rat testis. MaterialsAndMethods In this experimental study 30 male wistar rats, were divided into five groups (N=6). Control, sham (received olive oil), experimental group 1...
