EGFP expression during intestine development in the transgenic mice. (A) Study of EGFP fluorescence by fluorescence dissecting microscopy. At stage E14.5 to 2 week, structures including the stomach, small and large intestines were included and examined. Due to the size, at the 3-week stage only stomach and small intestine and at 4 weeks small intestine alone were examined. Conditions were as described in the legends to Figure 2A. (B) Expression of EGFP during small intestine development. Fetuses at E14.5 stage of 3G line (left panel) and E15.5 stage of 16E line (right panel) were embedded in OCT compound. Frozen sections were examined by fluorescence microscopy. White arrow marked the proximal intestine and red arrow marked the distal intestine. MG: myenteric ganglion. Scale bar, 500 μm.
