Fig. 5From: Lung cells support osteosarcoma cell migration and survivalMigrated Osteosarcoma cells proliferation and survival increased in the HULEC-5a CM. a SaOS2, SJSA-1 and U2OS cells were induced to migrate to HULEC-5a or MRC5 CM for 48 h, followed by culturing the migrated OS cells in regular culture medium for another 10 days. OS cells were fixed and visualized by Giemsa staining. OS cell migration in regular medium is used as control. b Quantitative assays for Giemsa staining positive colony of the OS cell in Fig. 5a. c BrdU staining of the SaOS2 and SJSA-1 cells migrating to HULEC-5a and MRC5 CM. Brown color represents the positive stainingBack to article page
