Medical Term:

mesenchymal cells

 

Definition: fusiform or stellate cells located between the ectoderm and endoderm of young embryos; the shape of the cells in fixed material is indicative of the fact that in life they were moving from their place of origin to areas where they would become reaggregated and specialized; most mesenchymal cells are derived from mesoderm, but in the cephalic region they also develop from neural crest or surface ectoderm; they are the most strikingly pluripotential cells in the embryonic body, developing at different locations into any of the types of connective or supporting tissues, as well as smooth muscle, vascular endothelium, and blood cells.
