[In-vivo marking of human tumors using BUDR for flow-cytometry determination of kinetic cell parameters].

The flow-cytometry results of solid, human tumours are reported which were labelled with Bromodeoxyuridine in vivo. The preparation of the single cell suspension is prescribed. The S-phase percentage could be determined exactly in all cases but one. It is a rapid procedure which gives results in one day and the in vivo labelling had no adverse effects.
