About the Book

From a quiescent state in early pregnancy to a highly contractile state in labour, the myometrium displays tremendous growth and remodeling which is thought to occur as a result of phenotypic modulation of uterine smooth muscle cells (SMCs). This study tested the hypothesis that during pregnancy, phenotypic modulation of myometrial SMCs is regulated by endocrine and mechanical signals that are mediated by growth factors and cytokines, and the eventual onset of contractile phenotype is characterized by changes in contractile machinery. We demonstrated that the gene expression of growth factors (IGF system, TGFbeta family, EGFR), cytokines (Ccl2, HGF, Edn system), and contractile proteins (actins, alpha-Tpm, SM22alpha) were affected by pregnancy in the rat myometrium. They were differentially expressed associated with particular phase(s) of myometrial differentiation. Furthermore, TGFbeta3 protein expression was found to be stretch-regulated near term. Taken together, these results suggest that programmed differentiation of myometrial SMCs is regulated by growth factors, cytokines, and contractile proteins.
