Mouse stromal cell lines (FLS lines), established from the livers of 13-day gestation mouse fetus, supported the proliferation and differentiation of the erythroid progenitor cells from mouse fetal livers and bone marrow in a semisolid medium in the presence of erythropoietin. A large erythroid colony of over 1000 benzidine-positive erythroid cells was developed from a single erythroid progenit...

Abstract Background Pancreatic stellate cells (PSCs) occupy the majority of pancreatic cancer microenvironment, contributing to aggressive behavior (PCCs). Recently, anti-fibrotic agents have proven be an effective strategy against cancer, but clinical trials shown little efficacy, and driving mechanism remains unknown. N-acetyl-cysteine (NAC) is often used for pulmonary cystic fibrosis. Piogli...

The proto-oncogene c-fos was transiently upregulated in primitive hematopoietic stem (Lin-Sca-1(+)) cells stimulated with stem cell factor, interleukin-3 (IL-3), and IL-6. To investigate a role of the c-fos in hematopoietic stem cells, we used bone marrow (BM) cells from transgenic mice carrying the c-fos gene under the control of the interferon-alpha/beta-inducible Mx-promoter (Mx-c-fos), and ...

INTRODUCTION Gastrointestinal stromal tumors are the most common mesenchymal neoplasms of the gastrointestinal tract. These tumors represent more than 80% of all mesenchymal tumors found in the gastrointestinal tract, though they account for only approximately 3% of all gastrointestinal malignancies. Literature offers case reports, which describe symptomatic gastrointestinal stromal tumors and ...

endometrial stromal sarcoma represents a very rare pathological entity occurring as a malignant disease in women genital sphere, frequently in the age group of 40-50 years. low grade endometrial stromal sarcoma (lgess) is a rare uterine sarcoma constituting 0.2% of all the uterine malignancies with a good prognosis despite a tendency to recur. we report a case of 42 years old woman presented wi...

Introduction. Removal of the left and right lateral lobes liver in white rats leads to postresection portal hypertension, which is characterized by dilation plethora hepatic vein, mesenteric veins, esophageal gastric veins anterior abdominal wall, splenomegaly, ascites multiorgan failure.
 Objective research: study features remodeling structures atria at hypertension histostereometrically....

Hepatic stellate cells (HSC) play a major role in initiating the liver fibrogenic (wounding) response of the liver and can also orchestrate a pro-metastatic microenvironment in the liver in response to invading cancer cells. Here we explored the role of the hepatic stellate cells in colon carcinoma liver metastasis with emphasis on the contribution of the insulin-like growth factor (IGF) axis t...

dendritic cells (dcs) play an important role in induction of cellular immune responses. it seems that dcs that reside in different organs may be distinct in their ability to  induce immune responses. this study was done to address the differences between spleen and liver dcs in induction of immune response and/or tolerance. cd11c+  dcs were separated from the liver and spleen of c57bl/6 mice an...
