THE SPECIFICITY OF 4-AMINOPTEROYLGLUTAMIC ACID (AMINOPTERIN) FOR LEUKEMIC HEMATOPOIETIC TISSUE

Abstract
A study of the effect of aminopterin on the hematopoietic tissue of normal mice and mice with transplanted Ak 4 leukemia is reported. At less than lethal doses, aminopterin showed a striking inhibition specificity for neoplastic cell production.
