Publication number: 20220177845Abstract: This disclosure provides methods of making a megakaryocyte-erythroid progenitor cell (MEP), comprising differentiating a MEP precursor cell into a MEP in culture in the presence of an aryl hydrocarbon receptor (AhR) modulator. In some embodiments the AhR modulator is an AhR antagonist. In some embodiments the AhR modulator is an AhR agonist. In some embodiments the methods comprise culturing MEP precursor cells in the presence of an AHR antagonist and then culturing MEP precursor cells in the presence of an AHR agonist. In some embodiments the stem cell is a pluripotent stem cell. In some embodiments the MEP co-expresses CD41 and CD235. In some embodiments the number of MEPs produced in the culture increases exponentially. Methods of making a red blood cell (RBC) by culturing a MEP in the presence of an AhR modulator are also provided. Methods of making a megakaryocyte and/or a platelet, comprising culturing a MEP in the presence of an AhR modulator are also provided.Type: ApplicationFiled: August 20, 2021Publication date: June 9, 2022Inventors: George J. Murphy, David H. Sherr, Sarah S. Rozelle, Brenden W. Smith

Publication number: 20210299181Abstract: The present disclosure takes advantage of non-naturally existing, novel, anucleated platelets or platelet-like cells or platelet variants (collectively referred to as PLCs) or derivatives thereof (i.e., genetically engineered), which share at least one common receptor, ligand or an antigen with endogenous cells that are targets for autoantibodies and effectuate their clearance. The present disclosure also takes advantage of viral adhesion or entry receptors or genetically engineered PLCs or derivatives thereof, which are engineered to express viral adhesion or entry receptors, that specifically binds to viral proteins on viruses or viral particles and effectuate their clearance.Type: ApplicationFiled: March 26, 2021Publication date: September 30, 2021Inventors: Sunita R. Hett, Karen Weisinger, Yang Peng, Kyle P. McLaughlin, Christian G. Peters, Andrew R. Zukauskas, Brenden W. Smith, Silvia Giannini, Po-Shun Lee
