Abstract：Objective:To assess the risk of male infertility in the offspring conceived through assisted reproductive technology (ART) byin vitroinductionof the differentiation of embryonic stem cells (ESCs) derived from the embryos of the couples with male asthenozoospermia and Robertsonian translocation (RT) into germ cells.Methods:We established a CCRM16ESC line with the karyotype of 46,XY,+ 14,rob(13;14) (q10;q10) from the embryo donated by a patientwithasthenozoospermiaand RT and his wife by isolation of the inner cell mass of blastula,culturing,passaging,and amplification,followed by in vitro induction and differentiationof the ESCs into germ cells with ratinoic acid(RA) at 2 mol/L.Then,we analyzed the process of differentiation and the expressions of its related genes and compared them with those in the normal CCRM23ESCs.Results:CCRM16 showed the typical characteristics of ESCs,expressing the pluripotency makers of NANOG,OCT4,TRA-1-181 and SSEA4,forming embryoid bodies,and differentiating into three germlayer tissues in vitro and in vivo.Intervention with 2 mol/LRAinduced direct differentiation of the ESCs into germ cells.The expressions of the primordial germ cell marker geneDAZLand the meiosis marker geneSCP3were markedly decreased in the CCRM16 as compared with those in the normal CCRM23 ESCs.Conclusion:The CCRM16ESC linewith the karyotype of 46,XY,+ 14,rob(13;14) (q10;q10) has thetypical characteristics of ESCs but an abnormal process of differentiation into germ cells in the early stage.In vitroinductionof the differentiation of ESCs into germ cells can be used for assessing the risk of male infertility in the off-spring conceived through ART for asthenozoospermia patients.
