Tobias Cantz, Hannover Medical School
09:05 - 09:15 Interview Nicolas Rivron with Aljoscha Berve, Stemcell Network NRW, Düsseldorf
What is your definition of embryoids, blastoids, self-assembled embryos and do these differences matter?
Do you think the term “synthetic embryo” is justified”? 
What are your expectations on advanced embryoid cultivation in 10 years?
How do differing international regulations affect your current research?
Do you experience global differences in acceptance / funding options of your research?
09:15 - 09:25 Interview Hiromitsu Nakauchi with Tobias Cantz
What are your expectations on the use of human-animal chimera for organ development in 10 years?
If an organ is generated by embryo complementation with patient-derived iPS cells. Who owns the organ?
Germline contribution of human cells is a critical issue. But to what extent does neural chimerism matter?
How do differing international regulations affect your current research?
Do you experience global differences in acceptance / funding options of your research?
09:25 - 10:15 Panel discussion / plenum:
What characteristics are missing to make an embryoid a human being? And, what is missing to make a chimeric animal a human being?
Subsequent to the term “synthetic embryo”, do we have to contemplate the term “synthetic human being”? 
Are there “safety switches” that would address major doubts?
Could we envision a road map that guides a step-wise development advanced embryoids human-animal chimeras?
