title: [Comparative aspects of the white body of Cephalopoda and the bone marrow of mammals].
abstract: The compared observations carried out in the white body of the Cephalopod Todarodes sagittatus and in the bone marrow of the Mammalian Rattus rattus enabled us to note, especially on the electron microscope, some resemblances among the main cellular types, and namely between leucoblasts and promyeloblasts, between proleucocytes and promyelocytes and between leucocytes and granulocytes. These resemblances are due also to the presence, in both series, of indispensable conditions to the protein synthesis in the cytoplasm. In any case one can assume that the considered series are formed by "synthetic activity cells with irreversible behaviour".
