Image of the Month: Mouse embryo inside the yolk sac

At Baylor College of Medicine, Dr. Momal Sharif, a postdoctoral associate in the Department of Obstetrics and Gynecology working in the lab of Dr. Ignatia Van den Veyver, studies mouse embryo development from early post-implantation to postnatal stages.

In her studies, Sharif uses micro-computed tomography (micro-CT), a 3D imaging technique that uses X-rays to see inside an object. Micro-CT is similar to hospital CT scan imaging but on a smaller scale with greatly increased resolution.

“This method enables us to conduct 3D analysis of the embryo along with extra embryonic tissue,” Sharif said. “We aim to characterize structural defects within the embryo, yolk sac and placenta using this method.”
