Neural Progenitors (IMAGE) University of Florida Caption UF McKnight Brain Institute researchers were able to purify and grow highly adaptable cells called adult human neural progenitors from mature human brain tissue. The green marker indicates a support brain cell called an astrocyte and the red marker is an indication of a stem cell, which is highly valued for its ability to transform into any cell type. Blue marks the cell nucleus.
