Adrenal Gland - Extramedullary Hematopoiesis - Gallery

Adrenal gland, Cortex - Extramedullary hematopoiesis in a female F344/N rat from a chronic study. There is a focus of hematopoietic cells (arrow) in the cortex (zona fasciculata).

Adrenal gland, Cortex - Extramedullary hematopoiesis in a female F344/N rat from a chronic study (higher magnification of Figure 1). There is a focus of immature hematopoietic cells (arrow) in the sinusoids of the cortex (zona fasciculata).

Adrenal gland, Cortex - Extramedullary hematopoiesis in a male F344/N rat from a chronic study. There are multiple foci of hematopoietic cells (arrows) in the adrenal zona fasciculata.
