BST2 and cancer: Similar to wound healing, trans migration experiments show that in four isogenic cancer cell lines―4T1, 4T07, 168FARN, and 67NR, restoration of BST-2 expression in shBST-2 cells rescues cell migration, as documented by microscopy (Figure 4E–4H), image J analysis of microcopy data (Figure 4I–4L), hemocytometer-based cell counting (Figure 4M–4P), and spectrophotometry-based absorbance (Figure 4Q–4T).
