Cells were first filtered according to their expression pattern for the HCN subunits. Subsequent filtering was determined by ≥ 80% expression (+), ~ 50% expression (+/−), and < 10% expression (0). Numbers in the far right column represent the number of cells for each subgroup that expressed all of the HCN channels indicated and ≥ 80% expression for two or more of the remaining α subunits.
