Abundance and Significance of Neuroligin-1 and Neurexin II in the Enteric Nervous System of Embryonic Rats

Figure 3

The histological appearance and expressions of neuroligin-1 and neurexin IIα by immunohistochemistry staining (magnification ×400). The positively stained cells of both neuroligin-1 (A, B, C, and D) and neurexin IIα (a, b, c, and d) concentrated mostly in the myenteric plexus and the expression level of neuroligin-1 and neurexin IIα increased gradually along groups E16 (A, a), E18 (B, b), E20 (C, c), and Ep0 (D, d).
