Quantification of Trophoblast Syncytialization by Fluorescent Membrane Labeling.

Trophoblast fusion or syncytialization is a fundamental yet poorly understood process during placental development. Primary cultured cytotrophoblasts and human choriocarcinoma cell lines are commonly used to study trophoblast fusion mechanisms in vitro. Quantification of trophoblast fusion index is a key for the in vitro studies. In this chapter, we describe a new method to quantify fusion index, which is based on fluorescent labeling of the plasma membrane using Di-8-ANEPPS, a membrane potential dye. This method directly works on live cells, thereby is simple, economic, and reliable.
