Although the function of CD34 in resting endothelial cells and in tip cells during angiogenesis was not addressed in the present study, we speculate that the proposed anti-adhesive property of CD34 may also play a role in maintaining vascular lumina in resting tissues, as well as in allowing the migration of tip cells and the movement and probing of their filopodia through the tissue matrix.

The calculation of the migration speed of tip cells was performed as described previously (Yu et al., 2010).
