  • Scientists grow functional brain-like tissue without animal-derived materials.
  • The research team works at the University of California, Riverside.
  • Iman Noshadi leads the project as a bioengineering professor.
  • Prince David Okoro is the study's lead author and researcher.
  • The team makes the scaffold mainly from polyethylene glycol (PEG).
  • They reshape PEG into a porous, textured matrix for cells.
  • Donor stem cells attach, grow and form active neural networks.
  • The scaffold is about two millimeters wide and being scaled.
