Using the acrylic textile dye Lycramine brilliant blue JL, mature and immature megakaryocytes from human bone marrow specimens stained metachromatically bright lavender. This coloration was not observed in other types of bone marrow cells. After digestion with either diastase or ribonuclease, subsequent staining of marrow specimens did not reveal a significant diminution of the intensity of staining of megakaryocytes. However, after incubation with hyaluronidase followed by staining with Lycramine brilliant blue JL, staining of megakaryocyte cytoplasm was either imperceptible or very pale blue. Accordingly, at least one of the substances responsible for the staining reaction is acid mucopolysaccharide in the cytoplasm of megakaryocytes. With further experience and comparison with established immunologic and cytochemical techniques, staining of megakaryocytes with Lycramine brilliant blue JL may be a useful addition to the cytochemistry of blood and bone marrow cells.
