Human Stem Cell Variability (IMAGE) Allen Institute Caption Allen Institute researchers have found astonishing variability of the intracellular organization inside human stem cells -- even among cells that are clones of one another. Here is a sample of 100 cells from the Allen Cell Explorer showcasing that variability. Each structure is color labeled: magenta -- DNA, cyan -- cell membrane.
