Ascites spheroids disaggregate on mesothelial cell monolayers. Ascites spheroids from eight patients were plated on confluent mesothelial cell monolayers for seven days. The fold change in spheroid area was calculated at day 7. Bars represent the percentage of the total number of spheroids that disaggregated 2.0 to 4.9 fold (black), 5.0 to 7.9 fold (white), 8.0 to 10.9 fold (gray), or greater than 11.0 fold (striped) in area over seven days. P-values were < 0.05 for all samples at all time points, with the exception of samples 8 and 10 at day 1.
