KeratinoSens I believe comes from the HaCaT cell line being transfected with some particular plasmid. While I don't know of any companies that sell the cells themselves (geez that's a tongue-twister), you could make the cell line yourself; HaCaT is a keratinocyte cell line, and if you get transfection reagents for it (like https://altogen.com/product/keratinocyte-transfection-reagent-keratinocytes/) then you should be able to get the necessary plasmid in and voila, you should have KeratinoSens cells.
