Abstract: | Cell-substrate interactions between human blood neutrophils moving on a glass substrate in serum-free medium have been investigated using reflexion interference microscopy, high voltage and scanning electron microscopy (SEM). The contact pattern with the substrate differed considerably from that found in fibroblasts and the amoeba Naegleria. Discrete focal contacts could not be detected but large broad areas of very close contact (accounting for about 30% of the total contact area) could be found particularly associated with the uroid. Considerable loss of membrane material occurred as a result of breakdown of the uroid during locomotion. |
