The synthesis, transport and excretion of connective tissue macromolecules by smooth muscle cells

SMC-s both in vivo and in vitro have a function in matrix macromolecule production. Under certain conditions the synthesizing function of the SMC-s seems to be more important than their contractile function. The modified less differentiated SMC-s participate in the synthesis of connective tissue macromolecules while the differentiated "resting" SMC-s maintain the functional activity.
