[Induction and differentiation of induced pluripotent stem cells into macrophages: a review].

Induced pluripotent stem cells (iPSCs) are a type of cells similar to embryonic stem cells but produced by reprogramed somatic cells. Through in vitro differentiation of iPSCs, we can interrogate the evolution history as well as the various characteristics of macrophages. iPSCs derived macrophages are not only a good model for drug screening, but also an important approach for immunotherapy. This review summarizes the advances, challenges, and future directions in the field of iPSCs-derived macrophages.
