Fig. 3

Expression of SMAA mRNA was detectable in the peripheral cellular population at E13.5 and increased to significantly high levels in smooth muscle cells at E15 and E16. SM-MHC was detectable temporal slightly later than SMAA and increasing in expression at E15 and E16 (Mann-Whitney test, p<0.001). a, Serosal zone. a1, Smooth muscle layer. a2, Intermediate zone. b, Submucosal zone.
