Twin chick embryo update:
This next image is from day 3. Heart is still beating, blood islands are forming, but fewer than expected. The biggest difference is that the embryo has finally turned from its back to its side…a process that was delayed in this embryo; probably because it didn’t “know” which direction to turn…it chose one and we’re now looking at a lateral view.
We’re curious about how long this embryo will survive and whether the body and tail on the left-hand side will regress and/or die. Stay tuned. If we’re not too busy doing research and taking images of zebrafish eyes, we’ll update this feed soon.
