Ninl expression at E11.5 visualized by RNA-ISH on parasagittal sections of Hsd:ICR(CD1)® wild type embryos. (a/b/c) Sections through the embryo from parasagittal lateral to medial at 32× showing expression in the forebrain (FB), midbrain (MB) and hindbrain (HB), the neural tube (NT), the sensory organs, the dorsal root ganglia (DRG) and the intervertebral discs (IVD). (d) Section through the head at 50× showing expression in forebrain (FB), midbrain (MB) and hindbrain (HB). (e) latero-medial section through dorsal root ganglia at 100×. (f) Medial section through the vertebral column at 200× showing expression in the intervertebral disc (IVD) and neural tube (NT). (g) Section through the eye at 200× showing expression in the lens (L, blue arrow) and retina (RE, green arrow). (h/i) sections through the nasal epithelia (NE) and otic vesicle (OV), respectively, at 100× (black arrows).
