1. A method to obtain progenitor and/or stem cells from a subjectwhich method comprises(a) administering to said subject a compound of the formula

  • (1)or pharmaceutically acceptable salt or prodrug form thereofwherein Z is a cyclic polyamine containing 9–

    32 ring members of which 2–

    8 are nitrogen atoms, said nitrogen atoms separated from each other by at least 2 carbon atoms, and wherein said heterocycle may optionally contain additional heteroatoms besides nitrogen and/or may be fused to an additional ring system;

    or Z is of the formula embedded imagewherein A comprises a monocyclic or bicyclic fused ring system containing at least one N and B is H or an organic moiety of 1–

    20 atoms,Z′

    is either embodied in a form as defined by Z above, or is of the formula



    Xwherein each R is independently H or straight, branched or cyclic alkyl (1–

    6C), n is 1 or 2, and X is an aromatic ring, including heteroaromatic rings, or is a mercaptan;


    represents a bond, alkylene (1–

    6C) or may comprise aryl, fused aryl, and/or oxygen atoms contained in an alkylene chain, and/or may contain keto groups and/or nitrogen or sulfur atoms;

    in an amount effective to mobilize said progenitor and/or stem cells into the peripheral blood of said subject;

    followed by(b) harvesting said progenitor and/or stem cells by apheresis.
