The morphology of the bone marrow of the mouse

For an investigation on the morphology of the cells of the bone marrow of the mouse, use was made of 2 stains: MAY-GRUNWALD-GIEMSA (MGG) and methyl-green-pyronine-stilbene (MPS). The results are reported, and are compared with each other and with those obtained with the LENDRUM stain. To compare results in the same cell, its coordinates were determined with a computer-controlled scanning microscope after staining with the first method, and the preparation was then destained and restained for evaluation of the second method. The advantages and disadvantages of the stains are discussed, and it is concluded that for the evaluation of the morphology of the eosinophilic leukocyte, the MPS stain seems to be superior.
