We describe methods of manipulating Xenopus laevis immature oocytes, in vitro maturation of oocytes to eggs, and intracytoplasmic sperm injection. This protocol allows degradation of some maternal proteins and overexpression of genes of interest at fertilization, and hence is valuable to study roles of specific factors in early embryonic development.
Polyurethane catheter insertion into the aortic lumen and suture ligation of the aorta induce chronic hypoxia due to hypoperfusion of the adventitial vasa vasorum. This article describes a novel animal model of abdominal aortic aneurysm (AAA) with characteristics similar to those of AAA in humans.
We describe a dramatically improved method for mouse cloning using trichostatin A, vitamin C, and deionized bovine serum albumin. We show a simplified, reproducible protocol that supports efficient development of cloned embryos. Hence, this method could become a standardized procedure for mouse cloning.
