Figure 2. Expression of the integrin α6 subunit mRNA in the P10 mouse cerebellum. (A) In situ hybridization analysis of the α6 integrin mRNA on sagittal sections of P10 mouse cerebellum. The α6 mRNA was present in the PCL. Scale bar, 100 µm. (B) High magnification view of the boxed area in (A) showed a strong expression in the cell bodies of Purkinje cells (arrows). Scale bar, 40 µm. EGL, external granular layer; ML, molecular layer; PCL, Purkinje cellular layer; IGL, internal granular layer.
