I used 0.5 ml/well of accutase for 3 minutes at 37C. Then I added 4 ml/well of PBS and I did the optional centrifuge at 300g 3 minutes (the minimum g of the centrifuge in my lab). In the end I resuspended cells in 5 ml of M1.

Dear Chiara
Sometime the success of EBs could dipend by the quality of your PSC culture. You could also try alternative methods for generating EBs, like the hanging drop method. For example here you can find a review describing various EBs methods: https://pubmed.ncbi.nlm.nih.gov/25900308/.
Kind regards,

Dear Chiara Fasano,
you can try and add 10 µM Rock-Inhibitor (Y-27632) to the M1 media for the first 24hours. We have observed the same problem for some iPSC-lines. The addition of 10 µM Rock Inhibitor usually helps.
Best,
Annika
