Morphologic aspects of the leading lamella in locomotive normal and neoplastic blood cells. A study by scanning electron microscopy (SEM).

A leading lamella is part of every translocative cell, irrespective of nature and origin. The morphological aspect of this cytoplasmic extension, however, varies and, among the different cell types, locomotive blood cells show the greatest diversity with regard to position, size and shape. In this communication, SE micrographs of benign and malignant blood cells of different classes are presented. The dynamic interpretation attempted for the description of the static photographs is based on analyses of time-lapse films which show the activities of the live cells.
