Comparison of tumor suppression in the lungs of wild mice (top row) and 'humanized' mice (bottom row). First column represents untreated mice. Second column, mice treated with KRN7000, a synthesized compound. Third column, mice treated with a new compound, AH10-7. Results show the newly synthesized compound AH10-7 is at least as effective as KRN7000 in suppressing growth of melanoma cells.
