Fig. 1From: Macrophages-derived exosomal lncRNA LIFR-AS1 promotes osteosarcoma cell progression via miR-29a/NFIA axisMacrophages promote the proliferation and invasion but inhibit apoptosis of osteosarcoma cells. a The cck-8 assay for cell proliferation. b Colony formation assay. c EdU assay for cell proliferation. d Flow cytometry was used to detect the apoptosis of osteosarcoma cells. e Wound-healing assay results showed Mφ-CM could promote the migration of 143B and U2OS cells. f–g Transwell assays indicated that macrophages could promote both migration and invasion of osteosarcoma cells. **p < 0.01Back to article page
