title: Histogenesis of the myeloid system in geese.
abstract: Using light- and electron-microscopy the location in organs and the time-course of appearance of cells of the myeloid system was studied in goose embryos and goslings. Large numbers of cell forms representing different stages of granulocytopoiesis were found between 15 and 28 days of incubation in the mesenchyma of the kidney and in the reticular tissue of the spleen, but not in the liver and other organs. Thus, before the haemocytopoietic activity of the bone marrow, an activity typical of adult birds, develops, in geese embryonic extra-medullary granulocytopoiesis is characterised by a renal-lienal stage.
