Objectives: The uterus responds to an implanting blastocyst by undergoing extensive tissue modification leading to decidualization. This modification includes differentiation and apoptosis of epithelial as well as stromal cell compartments. It is generally accepted that the decidual cell regression pattern is similar to the pattern of initial differentiation, suggesting that decidual cell death is the end point of timed differentiation. However, the molecular mechanisms controlling these events are not understood clearly. Therefore, we aimed to investigate the involvement of apoptotic factors using an in vitro cell culture system.
