In the chorionic plate and stem villi of the human placenta besides the fetal blood vessel system a second extravascular contractile system (EVCS) exists. The cells of this system contain contractile and intermediate filaments and are dipeptidyl peptidase-IV- and NO-synthase-type-I-(NOS)-immunoreactive. Therefore it can be assumed that these cells cleave the vasodilator Substance P (by DPP IV) and produce NO (by NOS) and may contribute to a modulation of the EVCS.
