The two populations were isolated from first trimester placentas and identified using the specific surface markers, EGFR (vCTB) and HLA-G (pcEVT).2017/02/01GSE80996GSM2140131GSM2140121GSM2140134GSM2140123GSM2140125GSM2140136GSM2140117GSM2140127GSM2140138GSM2140119GSM21401291055880996Homo sapiens[28167044]
