Fig. 6. (a) In vivo UCL imaging of FUCP-1 in 4T1 tumor-bearing BALB/c mice. (b) Experimental procedures. (c) Changes of tumor volumes obtained from the 4T1 tumor-bearing BALB/c mice under different treatments. Data are expressed as mean ± standard deviation (n = 6, data are expressed as mean ± SD, ***p < 0.001 determined by Student's t test). (d) Photographs of the corresponding tumors. (e) Hematoxylin & eosin (H&E) stained images of the dissected tumor tissues. (f) Body weight changes of the BALB/c mice under different treatments.
