My guess…is an HSC (hematopoietic stem cell).
Because although these cells aren’t known for their civil disobedience, they do have a certain knack for making people more tolerant.
In fact, that’s why Dr. Megan Sykes, Director of the Columbia Center for Translational Immunology, finds them so interesting. She wants to use these cells to teach a patient’s body to become tolerant to the cells of an organ donor. The objective: improving long-term graft acceptance and eliminating the need for chronic immunosuppression (which, for the record, is not fun).
