FN1 and leukemia: Figure 2 shows their growth (Figure 2A,B), cytotoxicity for the human leukemia monocytic cell line (THP-1) (Figure 2C) and attachment to a fibronectin-coated surface (Figure 2D) under both control and LSMMG conditions. We observed that the LSMMG culture did not affect the growth (Figure 2A,B) or cell morphologies of either strain (Figure S1).
