Dr. Madeline Lancaster discusses how brain organoids can be used to model human biological complexity, including the formation of long-range nerve tracts capable of stimulating muscle contractions in vitro. This event is part of the STEMCELL Seminar Series and was recorded in our Cambridge, UK office. By inviting local scientists to attend talks from leading researchers, the STEMCELL Seminar Series helps scientists keep current with cutting edge technologies and innovations in their field.
