Figure 6D shows that between Day 8 and 17 the wt-wnt1-derived tumors showed a small growth advantage over the wnt1-RARα1/KO tumors, but in the next seven days they grew exponentially, reaching the weight of 500 mg, (calculated from the measurements of tumor diameter), while the growth of wnt1-RARα1/KO tumor leveled off at about 60 mg. Here, WNT1 is linked to neoplasm.
