Fig. 2.
TrkC staining of PV. The perikaryal cytoplasm is stained at all ages, albeit to different degrees. Single arrows, globular bushy cells; double arrows, stellate cell; large arrows, cells in the insets. The P30 inset shows a typical globular bushy cell with unstained eccentric nucleus. The large arrowhead points to the nerve terminal region around the soma, which is unstained, next to a stained astrocyte (thin arrows point to the cell body and astrocytic processes). Next to the astrocyte are two oligodendrocytes (asterisks). The cytoplasmic stain in both P30 and P14 insets is granular, unlike the cell in P8 (lower inset). In the P8 main panel and the upper inset, astrocytic processes (thin arrow) between two neurons are stained. Scale bar = 20 μm; 5 μm for insets.
