Expression and functional evidence of the prostaglandin F2alpha receptor mediating contraction in human umbilical vein.

Our purposes were to perform the pharmacological characterization of PGF(2alpha) receptor (prostanoid FP-receptor) involved in human umbilical vein contraction and confirm its expression in this tissue. Umbilical cords from healthy patients after full-term deliveries were employed. The vein was dissected out of cords and used for either isolated organ bath or reverse transcription-polymerase chain reaction (RT-PCR) and Western blot assays.
