Text style in column 1 indicates pathologist assigned histologic grade of the original primary tumor source of each cell line. Low grade – Regular; Intermediate grade – italics; High grade – bold.

Asterisks represent p<0.005 between control and coculture values within each row.

SubG1 values (range between 0–6%, unchanged by coculture) are included in the % calculation. The combined values of all phases = 100%.
