Lp + Sb = lamina propria and submucosa; Tm = tunica muscularis; pbt = pluripotential blastemic tissue.
The pluripotential blastemic tissue of groups I and II, which will later give rise to the lamina propria and submucosa, were not statistically compared owing to the fact that one structure will give rise to various others.
P < 0.005 vs. Group I;
P < 0.005 vs. Group III.
