ITGAM and chronic graft versus host disease: Lv showed that G-CSF induced the expansion of M-MDSCs (Lin−HLA−DR−/lowCD33+CD11b+CD14+CD15dimCD16−) and eMDSCs (Lin−HLA-DR−/lowCD33+CD11b−/lowCD14−CD15−CD16−) in the graft are negatively correlated with the incidence of acute and chronic GVHD without significant influence on relapse and survival [64].
