Bioengineered 3-Dimensional Brain Tissue (IMAGE) New York Stem Cell Foundation Caption Bioengineered 3-dimensional brain tissue model comprised of neurons (green), astrocytes (red) and their nuclei (blue) to study the biology of human brain diseases. These cells were differentiated from human induced pluripotent stem cells and grown for more than 2 years in a 3D silk scaffold tailored to emulate the properties of native brain tissue.
