Iron uptake studies on erythroid cells.
Iron uptake from 55Fe-labelled transferrin, ferric citrate and the two fungal sideramines, ferricrocin and fusigen was studied using four erythroid cell cultures: Friend virus-transformed erythroleukemic cells (mouse), transformed bone marrow cells, Detroit-98 (human), reticulocytes (bovine), bone marrow cells (rabbit). The present comparative study reveals pronounced differences in iron uptake behaviour. Compared to transferrin, ferric citrate and the sideramines are preferred in transformed erythroid cells. In reticulocytes transferrin and ferric citrate showed a better uptake as compared to the two sideramines. Primary bone marrow cells showed nearly equal iron uptake rates using transferrin or ferricrocin.
