title: Description of a suicide technique in vitro for granulocytic stem cells (CFUc) by hydroxyurea on normal human bone marrow.
abstract: It has been possible, by studying 15 normal human bone marrow samples, to develop a technique for the suicide effect in vitro by hydroxyurea (H.U.), applied to human granulocytic stem cells (CFUc). This study suggests a contact time of medullary cells from 60 to 80 minutes in the presence of a hydroxyurea concentration 6 mM per 10(6) cells per ml in vitro. Preliminary results concerning the clusters are discussed.
