Figure 4From: High resolution ultrasound-guided microinjection for interventional studies of early embryonic and placental development in vivoin miceHistological detection of injected beads. Implantation site (tissue autofluoresces orange) containing green fluorescent beads collected a few hours following ultrasound-guided microinjection into the ectoplacental cone region at E7.5. Beads visualized in 50 μm frozen sections were primarily localized to the targeted ectoplacental cone region. AC, amniotic cavity; Emb, embryo; EPC, ectoplacental cone; Exo, exocoelomic cavity; YSC, yolk sac cavity.Back to article page
