Background: Radiation-induced molecular changes on the endothelial surface of brain arteriovenous malformations (AVM) may be used as markers for specific vascular targeting agents. In this study, we examined the level of expression of platelet endothelial cell adhesion molecule-1 (PECAM-1) on brain endothelial cell surface after radiation treatment, with the aim of targeting the radiation-induc...

Objective(s):Mesenchymal stem cells (MSCs) derived from Wharton’s jelly (WJ-MSCs) are now much more appealing for cell-based infertility therapy. Hence, WJ-MSCs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. Materials and Methods: MSCs were isolated from human Wharton’s jelly and treated with BMP4, retinoic acid (RA) or co-cultured on huma...

purpose: to separate and characterize orbital fat-derived stem cells (ofscs) and compare its cellular and molecular properties with those of bone marrow-derived mesenchymal stem cells (mscs) and adipose-derived stem cells (ascs). methods: stem cells from orbital fat, abdominal fat and bone marrow aspirates have been isolated. we assessed stem cell specific cell surface markers using cytometry, ...

A null cell leukemia cell line, THP-5, was established from the peripheral blood of a patient with acute null cell leukemia. THP-5 cells were characterized by the presence of Ia-like antigen and the absence of other cell surface markers examined. Despite the presence of Ia like antigen, THP-5 cells had no stimulating capacity in autologous or allogeneic mixed lymphocyte reaction.

Synovial tissue obtained at synovectomy of the knee joint in 21 patients with rheumatoid arthritis contained a significantly lower proportion of T lymphocytes as measured by spontaneous rosette formation with nonsensitized sheep red blood cells than did synovial fluid or blood from the same patients. There was on concomitant increase in synovial tissue lymphocytes with B-cell markers such as su...
