Kazhdan and Lusztig introduced the $W$-graphs, which represent the multiplication action of the standard basis on the canonical bais in the Iwahori-Hecke algebra. In the Hecke algebra module, Marberg defined two generalied $W$-graphs, called the Gelfand $W$-graphs. The classification of the molecules of the type $A$ Gelfand $S_n$-graphs are determined by two RSK-like insertion algorithms. We finish the classification of cells by proving that every molecule in the $S_n$-graphs is indeed a cell.
