Method for enhancing proliferation or differentiation of a cell using ob protein

摘要

Uses for WSX ligands in hematopoiesis are disclosed. In particular, in vitro and in vivo methods for stimulating hematopoiesis (e.g., myelopoiesis, erythropoiesis and especially, lymphopoiesis) using a WSX ligand (e.g., anti-WSX receptor agonist antibodies or OB protein), and optionally another cytokine, are described.
