Drugs that stimulate production of RBCs are erythropoietics, those that produce WBCs are colony-stimulating factors, and those that increase platelets include a special interleukin. These drugs perform the same function as their endogenous counterparts.
However, maturation, activation, and some proliferation of lymphoid cells occurs in the spleen, thymus, and lymph nodes.
