Lancaster et al. describe a protocol to generate cerebral organoids from H9 ES cells.
On Day 0 ES cells or iPSCs were dissociated from mouse embryonic stem cells (MEFs) and separated to make single cells. Cells were then plated in 96-well plates in human ES media containing 50 μM Y-27632. Embryoid bodies were fed every other day for 6 days.
On Day 6 cells are transferred to 24 well plates and grown in induction media. They are fed every other day for 5 further days.
On Day 11 tissue is transferred to droplet Matrigels containing differentiation media. After 4 days of stationary growth the tissue droplets are moved to a spinning bioreactor, and grown in differentiation media containing retinoic acid (RA).
