Oxygen saturation in E14 mouse embryo and placenta

Pregnancy research - Mouse embryo and placenta showing oxygenation

In vivo 3D rendered coregistered high-resolution ultrasound (greyscale) and photoacoustic (red, white and blue) image of an E14 embryo and its associated placenta (on left).  The photoacoustic signal represents a parametric map of oxygen saturation with red values representing higher sO2.  The image was acquired while the mother was breathing 100% oxygen.
