Abstract:
When rabbit peritoneal macrophages were cultured in serum and Tyrode medium, numerous membranous structures varying in size and transparency were observed to cover the surface in complex cascading patterns. Modifications in the methods of fixation and drying probably accounted for the new perspective of macrophage surfaces gained in this study.
