A photomicrograph showing new tissue growing in the stroke cavity in a mouse. Red tubes are blood vessels; green filaments are nerve fibers.
Left: Olig2 expression (blue) results in reduced Hes gene expression (red) and increased motor neuron formation (green) in the developing mouse spinal cord. Right: in the absence of Olig2, Hes expression increases and motor neuron formation decreases.
Human embryonic stem cell-derived neurons (green) showing nuclei in blue. Left: with retinoic acid added. Right: with retinoic acid and BMP4 added, creating proprioceptive sensory interneurons (pink).
