Figure 1From: Generation of diverse neuronal subtypes in cloned populations of stem-like cellsNeurons develop from ES, EC and NE-4C cells in response to treatment with retinoic acid. Cultures were stained for neuron-specific βIII-tubulin in a phase of differentiation corresponding to stage 4 of NE-4C development: the 15th day of induced differentiation of R1 (ES), the 4th day for P19 (EC) and the 7th day for NE-4C.
