Abstract
Midbrain astrocyte and co-culture for mix-genetic experiments.
Steps
Intro
Midbrain NPC were generated following the publish protocol https://www.protocols.io/view/midbrain-organoid-differentiation-in-spinner-flask-rm7vzbnr4vx1/v1 with modifications listed bellow.
NPC generation
From a 80% confluent plate of iPSCs in a 10 cm plate.
Wash with 5ml of PBS
For the passaging add 3 mL of
Add 5 mL of StemFlex , gently mix and transfer to a 15 ml conical tube.
300rcf,25°C
Resuspend the cells in 1 mL of StemFlex with rock inhibitor and Count the cells using
