The effects of oxygen treatments on angiogenesis and lymphangiogenesis in mouse embryoid bodies


ABSTRACT: This study investigates the processes of angiogenesis and lymphangiogenesis in an in vitro mouse Embryoid Body (EB) model while maintaining as closely as possible an in vivo environment that is observed in human and murine placental development. Several studies have documented that human placental development is profoundly influenced by oxygen tension. Further the developing murine embryo also experiences hypoxic conditions prior to parturition, which regulates early organogenesis and embryonic blood vessel formation in vivo. Embryonic stem (ES) cells derived from 129/SvJ mice were differentiated into embryoid bodies (EBs) and were subjected to two oxygen treatments: normoxia (21% O2) and hypoxia (2.6%). Hypoxia was achieved in a humidified chamber flushed with 95% N2/5% CO2 until the oxygen level was stably maintained at 2.6%. EBs were transferred on days E8, E12, E15 and E18 to hypoxia or maintained in normoxia. After 2 days of differential oxygen treatments, these EBs were analyzed at E10, E14, E17 and E20 respectively.
