Growth morphology of chHES‐3 cells with normal and abnormal karyotype. (a) No differentiation at the periphery of colony in karyotypically abnormal chHES‐3 cells. (b) Obvious differentiation in normal chHES‐3 cells. (c) karyotypically abnormal chHES‐3 cells exhibiting capacity for extensive differentiation into primary nerve cells. (d) In karyotypically normal chHES‐3 cells, some at borders of colonies become linear and radiate, showing fibroblast‐like cell morphology.
