Time lapse results of adherent and rolling leukocytes in a rat mesenteric venule in vivo.
(a) is the beginning of an observation, as a baseline and the yellow arrow A denotes a mesenteric venule while the yellow arrow B is a capillary. (b)–(i) Series of observation of leukocytes rolling after 90 minutes has elapsed. Compared to (a), C, D cells indicated by red arrows are adherent leukocytes and the other cells (E, F and G) indicated by blue arrows are rolling leukocytes along the venular wall. From (b) to (i), the time interval is 1 second. Scale bar: 30 μm.
