As CD24+Thy1+ mammary tumor cells from MMTV-Wnt1 mice have been reported to possess TIC properties [77], we first performed limiting dilution experiments to ask whether CD24+Thy1+ primary tumor cells from MTB;TetO-Wnt1;TTC;rYFP mice were enriched for TICs. The gene discussed is WNT1; the disease is neoplasm.
