Modelling microglial function with induced pluripotent stem cells: an update

It is becoming increasingly apparent that microglia, the immune cells of the CNS, and their peripheral counterparts, macrophages, have a major role in normal physiology and pathology. Recent technological advances in the production of particular cell types from induced pluripotent stem cells have led to an interest in applying this methodology to the production of microglia. Here, we discuss recent advances in this area and describe how they will aid our future understanding of microglia.
