introduction: this study was designed to investigate the characters of the human endometrial epithelial cells when cultured on either plastic or ecm (extracellular matrix) gel surface and to study ultrastructural features of cultured cells in comparison to endometrial tissue. material and methods: human endometrial tissue was obtained from patients who had undergone hysterectomy for uterine myo...
one of the locations of renal artery atherosclerosis is at the orifice of the renal artery, therefore thestructure of this orifice was assessed in 6 normal, adult male dogs by light microscopy (lm) andtransmission electron microscopy (tem). for the lm study, processed tissues were embedded in paraffinand sectioned serially into 6-μm thickness. sections were stained with orcein. for the tem stud...
Angiogenesis plays a key role in tumor growth and cancer progression. TIE-2-expressing monocytes (TEM) have been reported to critically account for tumor vascularization and growth in mouse tumor experimental models, but the molecular basis of their pro-angiogenic activity are largely unknown. Moreover, differences in the pro-angiogenic activity between blood circulating and tumor infiltrated T...
Endothelial intercellular adhesion molecule 1 (ICAM-1) and ICAM-2 are both involved in lymphocyte extravasation during immunosurveillance and inflammation. To define their exact role during T-cell extravasation, we used mouse T cells and ICAM-1-/-ICAM-2-/- brain endothelioma cells. ICAM-1-/-ICAM-2-/- brain endothelioma cells did not support transendothelial migration (TEM) of T cells in vitro. ...
Background and Aim: In the present studysynthesis of silver nanoparticles and the assessment of its toxicity against the proliferation of osteosarcoma cells were done. Materials and Methods: To confirm the production of silver nanoparticles, UV-Visible spectroscopy, X-ray diffraction, and TEM analyses were performed. MTT assay was used to evaluate the toxicity of nanoparticles against cancer c...
Chronic lymphocytic leukemia (CLL) cell migration into lymphoid tissues is an important aspect of the pathobiology of this disease. Here, we investigated the role of ephrin-A4 (EFNA4) in the transendothelial migration (TEM) capacity of CLL and normal B cells through interacting with endothelial EphA2 (erythropoietin-producing hepatocellular carcinoma). CLL cells showed a remarkable impairment i...
Malignant lymphocyte migration into lymph nodes is an important aspect of chronic lymphocytic leukemia (CLL), yet little is known about the processes involved. Here we demonstrate that CLL cells migrate across vascular endothelium in response to at least 3 chemokines, namely, CCL21, CCL19, and CXCL12. Moreover, transendothelial cell migration (TEM) in response to CCL21 and CCL19 was significant...
Effector (TEM) and central memory (TCM) T cells have been recently described as the main memory T-cell subsets generated after primary immune response, with a potential role in graft rejection after rechallenge with alloantigen. Because of their effector function, they could be involved in driving the response against the allograft, leading to rejection. In this study, we sought to investigate ...
