embryonic origin of smooth muscle cells
Embryonic and Postnatal Development of the Smooth Muscle: The vascular smooth muscle cells (SMCs) which populate different vessels arise from several lineages within the developing embryo.t was also shown that at postnatal and adult stages, stem cells from specific niches can contribute to normal and damaged smooth muscle tissue. As such, molecular signatures of the different smooth muscle cell origins are unique and respond rather differently to the same secreted cues.
