GQDs attenuate tube formation and sprouting of HUVECs. A Representative images of GQDs inhibited tube formation of HUVECs. B Quantitative of the relative tube formation rate for each group. C Representative images of GQDs inhibited angiogenesis in sprouting assay. D, E HUVECs sprouting was quantified as sprouting length of HUVECs and sprouts numbers surrounding the spheroid. Error bars represent mean ± SD. *P < 0.05, **P < 0.01
