Fetal-sex determination of human placental tissues

It is now demonstrated that the sex-specific maternal-placental-fetal interaction plays an important role in placental functions and pathologies. Determination of fetal-sex may therefore be an important consideration in studies using placenta samples. In this present study, we describe a simple, fast, and cheap protocol, which allows the fetal-sex determination of placental tissues from various starting materials (villi or formalin-fixed, paraffin-embedded (FFPE) tissues, isolated cytotrophoblasts or cellular debris from whole cell lysates, and cDNA) by a single duplex PCR reaction followed by agarose gel electrophoresis.
