Production and physiological function of granulocyte colony-stimulating factor in non-pregnant human endometrial stromal cells.
Effects of granulocyte colony-stimulating factor (G-CSF) on proliferation and differentiation of normal human endometrial stromal cells were investigated in an in vitro decidualization culture of stromal cells. Unstimulated stromal cells secreted little prolactin and G-CSF, whereas 8-Br-cAMP-stimulated stromal cells secreted higher levels. There was no relationship, however, between the levels of prolactin and G-CSF secreted from the stimulated cells. Detectable levels of prolactin secretion were not found in two of six stromal cell cultures stimulated with 8-Br-cAMP; however, these two culture supernatants contained high concentrations of G-CSF. Co-stimulation of the stromal cells with 8-Br-cAMP and G-CSF enhanced prolactin secretion from the stimulated cells in a G-CSF concentration-dependent manner without any change in viable cell numbers. However, G-CSF did not affect prolactin secretion or viable cell numbers of 8-Br-cAMP-stimulated decidualized cells. These results indicate that G-CSF enhances cAMP-mediated decidualization of human endometrial stromal cells in an autocrine or paracrine fashion.
