Fig. 7From: Doxorubicin-loaded liposomes surface engineered with the matrix metalloproteinase-2 cleavable polyethylene glycol conjugate for cancer therapyCAM vasculature development on day 12 of egg development treated with liposomal formulations. (A) shows the stereomicroscope of the CAM vessels. (B) shows relative vascular density as compared to the control group. Data are expressed as mean ± standard deviation (n = 3). The statistical significant differences are designated as follows: *P < 0.05, **P < 0.01, ****P < 0.0001Back to article page
