Abstract: A machine includes a trailer frame, a tongue, a plurality of wheels, and an implement assembly. The tongue extends away from the trailer frame and supports a coupling. The plurality of wheels are coupled to the trailer frame. The implement assembly is coupled to the trailer frame, and includes a plurality of independent implement mounting assemblies coupled to a mounting rail. The independent implement mounting assemblies each include an arm, an implement, and a spring. The arm is selectively coupled to the mounting rail. The implement is coupled to a first end of the arm. The spring is coupled to a second end of the arm opposite the first end. The spring is configured to oppose movement of the implement relative to the mounting rail.

Abstract: Methods for enhancing and disrupting activity of the aryl hydrocarbon receptor (AHR) and cells having disrupted or enhanced AHR activity. The methods and cells may be used to enhance production of specific cell populations during hemato-endothelial cell or hemato-lymphoid cell development.
