A series of 9 photos of a chicken embryo section electroporated with a control EGFP plasmid at the DML level and reincubated for 24 h.

<p>Each photo shows movement of cells in 1 h time interval. At 0 h the EGFP transfected cells are seen in the DML. At later time points, the dynamics of the transfected cells are visible, with cells moving to the subectodermal space above the neural tube (black arrows), and additionally migrating to the immediate neighbourhood of the neural tube (white arrows) and the myotome. These dynamic movements are characteristic of a normal distribution of DML cells, where DML cells migrate to the subectodermal space in order to form the dorsal dermis and to the myotome to form the muscle. The red outline indicates the DML. Scale bar: 100 μm.
