Abnormal Expression of Fgf9 during the Development of the Anorectum in Rat Embryos with Anorectal Malformations

Figure 2

(a, b) On E14, URS divided the cloaca into the urogenital sinus and hindgut clearly. Fgf9-positive cells were mainly present in the mesenchyme, and a few positive cells were seen in the intestinal epithelium and CM. (c, d) In the ARM embryos, the distance from the hindgut to CM was relatively long. Staining of Fgf9-positive cells in the mesenchyme was faint. URS: urorectal septum; H: hindgut; U: urethra; CM: cloacal membrane. Original magnification: ×100 (a, c); ×200 (b, d).
