I recently purchased a vial of Cynom-K1 cells. I grew them up over several weeks as they were of VERY poor viability when they showed up. Expanded them, froze back 35 vials, saved a couple million and did a DNA extraction. Amplified an intron from a region for which I had Cyno and Rhesus sequence to confirm that these were actually Cyno cells. To my surprise they were HUMAN. A warning to anyone getting in cells, make sure you know what you have before starting any work with them.
