Effect of host LPA receptor on the homing of B16F10 lung metastasis. (A) LPA1 KO mice had a reduced number of lung nodules. n = 11 WT mice, and n = 8 LPA1 KO mice. (B) H&E staining of lungs from WT (left panel) and LPA1 KO mice (right panel). (C) No differences in the number of lung nodules were observed between WT and LPA2 KO mice. n = 12 WT mice, and n = 9 LPA2 KO mice. (D) H&E staining of lungs from WT (left panel) and LPA2 KO mice (right panel). (E) LPA5 KO mice had a reduced number of lung nodules. n = 10 WT mice, and n = 12 LPA5 KO mice. (F) H&E staining of lungs from WT (left panel) and LPA5 KO mice (right panel). P values are relative to control WT mice. Scale bar = 500 microns.
