The accuracy of diagnosis of hematological diseases from bone marrow aspirates and peripheral blood smears is considerably improved by use of histochemical stains. As hematopoietic cells differentiate and mature from the pluripotent stem cell and are committed to a particular cell line, the committed cell lines produce different substances, particularly enzymes, which can be identified by vario...

This is the first of three papers on the application of enzyme histochemical techniques to the study of developing and diseased muscle. This paper will deal with developing muscle in various laboratory animals, the second with developing human muscle, and the third with hereditary neurogenic atrophies in infancy and childhood. In 1678 Stefano Lorenzini had already observed that animal muscle co...
