Supports preclinical megakaryopoiesis research; leaves open clinical translation to thrombocytopenia.
Thrombopoietin acts synergistically with SCF, Epo, and IL-11 to stimulate megakaryocytic progenitor proliferation and uniquely promotes megakaryocyte maturation to high ploidy states in vitro.
Broudy et al. (1995) studied this question. Recombinant murine Thrombopoietin (Tpo) combined with SCF, Epo, or IL-11 vs. Cytokines alone was evaluated on CFU-Meg colony growth and megakaryocyte ploidy. Recombinant murine thrombopoietin synergistically enhanced CFU-Meg colony growth when combined with SCF, Epo, or IL-11, and uniquely generated megakaryocytes with ≥64N ploidy (30-35% of total).
