ABSTRACT
Objective To study the morphological characteristics of blood-tumor barrier(BTB)model of glioma in vitro. Methods After C 6 glioma cells/endothelia ECV 304 co-cultured mixed or in Transwell or on both sides of membrane of Transwell,the morphological characters of fenestra of endothelial cells,the junction between ECV 304 cells,the interface between C 6 cells and ECV 304 cells,and perivascular-end-feet of C 6 cells were observed under transmission electron microscope(TEM)and scanning electron microscope(SEM),and compared to BTB in 4 cases with human brain glioma. Results ECV 304 cells grown to confluence were not fenestrated,but with fomation of tight junction between ECV 304 cells after co-cultured with C 6 cells mixedly,in Transwell or on both sides of membrane of Transwell;It was not found that pseudopodia from C 6 cells as co-cultured in Transwell reaching into pore of Transwell;C 6 cells co-cultured on both sides of membrane of Transwell often sticked out to the ECV 304 cells,but with no pseudopodia from C 6 cells surrounded ECV 304 cells of penetrated the endothelia clefts.Perivascular-end-feet of C 6 cells were not integrant.These characters were similar to BTB in human brain glioma.Conclusion C 6 glioma cells/endothelia cell ECV 304 co-cultures on both sides of membrane of Transwell may simulate the morphological characters of BTB in vivo in some degree.;
