Macrophages interacting with vessels growing in an MDA-MB-231 xenograft.
Confocal time-lapse imaging of an MDA-MB-231 xenograft implanted in an mpeg1:NTR:mCherry;kdrl:EGFP embryo from 8.5 hpi to 32 hpi. Time-lapse image z-stacks were collected 10 min apart; movie was made at 7 frames per second. The most dorsal vessel was analysed in Fig. 4 between 21 hpi to 27. 25 hpi. Scale bar = 50 um.
