(a) For all groups, observation under inverted phase contrast microscope (100x) revealed that amounts of “C” shaped tube formation were formed significantly on the second day. The “C” shaped tube structure decreased gradually on the third day and the fourth day with increased cell numbers. The tube formation counts for the QSYQ-treated groups were more than that for the M group at the same timescale. (b) A dynamic observation revealed that tube formation rate of all the three QSYQ-treated groups increased significantly compared with that for the M group (), especially Q-L group.
