Abstract

Angiogenesis is a necessary step in tumor progression, and it correlates an unfavorable prognosis. In multiple myeloma, bone marrow microvessel density and angiogenesis grading correlated with plasma cell labeling index and are poor survival predictors, but the study of myeloma's angiogenesis is very rare. This article was to study the effect of multiple myeloma cell line conditioned media on the proliferation, migration and angiogenesis of human bone marrow endothelial cells (HBMEC). The multiple myeloma cell line conditioned media were obtained by using RPMI 1640 media containing 2% fetal bovine serum (FBS) to cultivate myeloma cell lines for 18 hours. Proliferation and migration of HBMEC were detected by using those media to cultivate HBMEC. Capillary tube formation was performed by using microcarriers cytodex-3 covered with HBMEC in three-dimensional fibrin matrices. The results showed that myeloma conditioned media induced HBMEC's proliferation and migration (P < 0.001), and those media induced capillary tube formation (length and width) of HBMEC (P < 0.001). It was concluded that myeloma cell lines induce HBMEC's proliferation, migration, and capillary tube formation by secreting several cytokines.
