For his doctoral thesis, Dr. Brinster developed the first reliable in vitro culture system for early mammalian embryos. (avma.org)
It's certainly not the first time people have CRISPR-ed viable mammalian embryos," Greely said. (cnn.com)

From there, Dr. Brinster became interested in modifying the development of animals and their germ lines, and he went on to become the first person to show that it was possible to colonize a mouse blastocyst with stem cells from older embryos. (avma.org)
Moreover, Dr. Brinster first demonstrated that teratocarcinoma cells could combine with blastocyst cells to form adult chimeric mice, establishing the feasibility of this approach to change the genetic character of mice. (avma.org)
