Figure 3. Differences in macrophage-induced stromal cell proliferation between BPHTF and BPHPF.

BPHTFs/BPHPFs were co-cultured with THP-1 cells in a transwell and assayed with MTT at 2, 4, and 6 days or RTCA. Differences between the two groups were analyzed by two-tailed Student's t test; *P< 0.05
