Pkd1 and Pkd2 were expressed in microdissected lateral walls of the lateral ventricle. a, Schematic drawing of the lateral wall of the lateral ventricle at P0. The red dotted line indicates the border between the anterior and posterior regions used for RT-PCR analysis. A, Anterior; D, dorsal; P, posterior; V, ventral. Scale bar, 1 mm. b, RT-PCR showing that Pkd1 and Pkd2 are expressed both in the anterior and posterior regions of lateral walls of the lateral ventricle at P0. ef1α was used as a loading control.
