IL-11 recovered colony formation capacity of SGC-7901/shMTA2 cell. A: Growth curves of SGC-7901/NC and SGC-7901/shMTA2 cells were not affected by rhIL-11 treatment. B: Colony formation in soft agar was assessed after rhIL-11 treatment. C: Number of colonies in SGC-7901/shMTA2/IL-11 group was more than it in SGC-7901/shMTA2/PBS group, and similar with SGC-7901/NC/PBS group. D: Size of colonies in SGC-7901/shMTA2/IL-11 group was larger than it in SGC-7901/shMTA2/PBS group.
