1 Release of annexin V-binding membrane microparticles from cultured human umbilical vein endothelial cells after treatment with camptothecin. Camptothecin annexin A5 Homo sapiens
2 In contrast, induction of apoptosis with 5 microM camptothecin, documented by 60-70% desquamation of HUVEC culture, annexin V-binding to the cells and DNA-fragmentation, led to a release of annexin V-binding microparticles (approximately 80,000 MP/103 cells). Camptothecin annexin A5 Homo sapiens
3 In contrast, induction of apoptosis with 5 microM camptothecin, documented by 60-70% desquamation of HUVEC culture, annexin V-binding to the cells and DNA-fragmentation, led to a release of annexin V-binding microparticles (approximately 80,000 MP/103 cells). Camptothecin annexin A5 Homo sapiens
4 CONCLUSIONS: Camptothecin treated HUVEC released different populations of annexin V-binding membrane microparticles at early stage after proapoptotic stimulation before detection of phosphatidylserine exposure on the cells or DNA fragmentation. Camptothecin annexin A5 Homo sapiens
