Modulation of syndecans in the uterus throughout the menstrual cycle: comparison between endometrium and myometrium.

Immunohistochemistry and semiquantitative analysis were used to examine and compare the expression of syndecans 1-4 in the endometrium and myometrium throughout the menstrual cycle. Syndecans molecules show different temporal and spatial expression during the menstrual cycle, and the modulation of syn-2 expression is statistically significantly correlated to morphologic and functional changes of the endometrium, particularly in the periovulatory period.
