Our iPSC-derived astrocytes are cryopreserved for convenience, and they are assay-ready within 48 hrsOnce thawed, Axol's astrocytes display all indicative astrocytic markers and will respond to glutamate stimulation, a key functional characteristic within 48-60 hrs. They also express markers showing that Axol's Human iPSC-derived astrocytes are physiologically representative of human primary astrocytes.
