More importantly, human hematopoiesis, demonstrated by the presence of cells expressing the human CD45 panleukocytary marker (4.54% of the total teratoma forming cells) and human progenitors (CD45+CD34+; 2.74% of the total hCD45+ cells) derived from edited PKD3iPSC e31 teratomas could also be detected in vivo (Figure S4B). Here, CD34 is linked to teratoma.
