Ultrastructural studies relating to the surface morphology of cultured cells

Abstract

ABSTRACT Scanning electron microscopy and a surface-replica technique for transmission electron microscopy have been used to study the ultrastructural features of cultured-cell surfaces The presence of microvilh measuring 0·1–0·2 μm in diameter by up to 5 μm in length has been noted as a regular feature of Landschutz ascites, ‘fibroblastic’ HeLa, and canine kidney, cells. The surfaces of chick mesenchyme cells were notably almost devoid of microvilh. The presence of microvilh at the cell surface is discussed briefly.
