WNT1 and neoplasm: The percentage of K6 expressing cells was calculated and compared demonstrating significantly fewer K6 expressing cells in the double transgenic samples (Figure 3D; n = 6 MMTV-Wnt1 tumors, 3 fields per tumor; n = 5 MMTV-Wnt1;MMTV-Wnt5a tumors, 3 fields per tumor, p-value = 0.0042).
