As shown in Table 2 , there were statistically significant differences between final average staining scores of the 2 groups, in terms of cytoplasmic SHH ( p =0.01), nuclear TBX18 ( p =0.01) and cytoplasmic TSHZ3 ( p =0.01) staining, as well as a borderline significance in nuclear TSHZ3 ( p =0.05) staining.
