An increased 3H-thymidine incorporation in the erythroid nucleated spleen cells has been found in vitro (mouse spleen cell culture) after incubation with epoetin alfa.
In vitro (hiire põrnarakkude kultuur) on leitud, et erütroidsete tuumadega põrnarakkudes sisaldub pärast alfaepoetiiniga inkubeerimist rohkem 3H- tümidiini.
