Examination of human and animal leukemic cells by high contrast scanning electron microscopy.

Investigation of human or animal (sheep and ox) leukemic cells by scanning electron microscopy enabled the identification and study of some ultrastructural details of the cell surface. A more detailed visualization by the high contrast technique of the same cell surface was obtained, in this work, for the first time in the biological field. This technique allows a better interpretation of any zone of the preparation examined, irrespective of the species from which the cells are collected.
