Ipsc Derived Microglia is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
iPSC-derived microglia are patient-specific microglia generated from induced pluripotent stem cells. They provide unprecedented opportunities to study microglial biology in neurodegenerative diseases and screen for therapeutic compounds.
- iPSC maintenance - Pluripotent colonies
- Mesoderm induction - BMP4, VEGF
- Myeloid commitment - IL-3, GM-CSF
