TSP-1 inhibited late EPCs tubule formation on Matrigel.

<p>(A) Late EPCs were plated on Matrigel with TSP-1 at different concentrations for 8 hrs (Scale bar = 200 µm, 100×magnification). (B) Quantification of total tube length per high power field (HPF, 100×magnification) was presented as mean±S.D. of three independent experiments (#p<0.05 versus no TSP-1 intervention, *p<0.01 versus no TSP-1 intervention).
