The early asymmetric cleavages of Caenorhabditis elegans embryos produce blastomeres with distinct developmental potentials. Here, we show that the caudal-like homeodomain protein PAL-1 is required to...
In Xenopus, localized factors begin to regionalize embryonic fates prior to the inductive interactions that occur during gastrulation. We previously reported that an animal-to-vegetal signal that occu...
With the use of blastomere analysis, it is possible to screen for serious genetic disease before initiating pregnancy through in vitro fertilization. The analysis provides information about an embryo'...
PURPOSE: To analyze the results of our transferred embryos, especially those that "changed" their blastomere nuclearity from Multinucleated (MN) to Mono-nucleated during development. METHODS: Pregnanc...
