Abstract
Having previously demonstrated that heme oxygenase (HO) is expressed on invasive trophoblast within the human placental bed, we have now further hypothesised that HO may play a role in trophoblast invasion. To begin to test this hypothesis we have used a well characterised in vitro model of trophoblast invasion to determine whether antibodies raised against HO-1 and HO-2, or selective inhibition of HO with the HO inhibitor zinc protoporhyrin-9 (Zn PP-9), would affect the invasive ability of trophoblast cells. Cytotrophoblast cells were purified from term human placenta then cultured on Matrigel-coated chambers in the presence or absence of HO antibodies or Zn PP-9. The HO-1 antibody had no effect on invasion whereas the presence of the HO-2 antibody significantly inhibition invasion (p less than 0.05). The presence of Zn PP-9 resulted in a significant reduction in invasion (p less than 0.05) whereas the vehicle alone had no effect. Taken together these results suggest, that at least in vitro, HO-2 may be important in controlling trophoblast invasion.
