Human Embryonic Stem cells differentiation state line distinguished distinct temporal temporal distributions of human brain samples and neuron cell lines. (A) Projection positions of Human Embryonic Stem cells differentiation time-course sample on Cell developmental state line (dataset GSE15209). The ES cells sample was set as origin point; other projection positions were normalized by ES cells sample. (B) Distributions of projection positions of human cortex tissue, normal fetal neuron stem cells and tumorigenic glioma neuron stem cells. Green represents normal tissue and cells. Red represents tumorigenic neuron stem cells.
