DDX53 and colonic neoplasm: An in vitro study showed that CT26 colon cancer cells exhibit higher proliferation rates when cultured in direct contact with MSCs (1:1) after 24 h (258 ± 124 pixels per field for CT26 vs. 594 ± 116 for CT26 + MSC, p = 0.02), 48 h (467 ± 159 px for CT26 vs. 1343 ± 258 for CT26+MSC, p = 0.01), and 72 h (552 ± 112 px for CT26 vs. 3128 ± 1122, p = 0.05) (Figure 1A, left upper panel).
