A connector of a sensor probe and its receptacle on a console have security mechanisms that ensure that the connector and the receptacle are properly connected and mated. Also provided are a method for producing the human CD34-negative progenitor cells and a method for determining the ability of CD34-negative progenitor cells to protect the vascular endothelium from immunologically mediated cytotoxic reactions. A fore-aft-positioning feature and a cross-car-positioning feature on the pillar trim member are spaced to permit contact with the fore-aft-locating feature and the cross-car-locating feature, respectively when the pillar trim member is assembled with the body frame pillar, so that only the single sheet metal layer determines the fore-aft and cross-car position of the pillar trim member. Increasing in the operating medium concentration in the cathode space in this manner causes a reduction in the freezing point and, when the system is started, an exothermic catalytic reaction. The connecting terminal may be arranged to accept a conductor and to thereby electrically couple the conductor to the first and second PCBs.
