Pigmented Cells in the Pineal Gland of Female Viscacha (Lagostomus maximus maximus): A Histochemical and Ultrastructural Study

Figure 7

Ultrastructural features of female pineal gland in mid pregnancy. The electron micrograph shows a large amount of premelanosomes (arrow) and melanosomes (m) within a pinealocyte (p) and a pigmented cell (pg). The arrowhead indicates a well-developed Golgi complex in the pigmented cell. The pinealocyte exhibited a large amount of mitochondria in the cytoplasm. Scale bars: 3 μm.
