An Electron Microscopic Study of Normal Blood and Bone Marrow in Pigs
Keyword(s):
The ultrastructure of blood and bone marrow cells in the normal pig was studied; the process of maturation of the different cell types was found to be essentially in accordance with that in other animal species. The eosinophilic granules had a pattern which differed from that in other mammals, being characterized by specific internal structure in the immature stages. During maturation, however, a homogenous appearance supervened. Moreover, the lymphocytic nuclei were found to have irregular shapes as compared with the light microscopic picture. The results are compared to some reported studies of other animal species.
