Abstract
Gene Regulatory Networks Regulating Endoderm Development
A major unanswered question in biology is how differentiation of the myriad cell types of the adult body is hardwired in the genome. Using the frog as a model system, our goal is to elucidate the mechanisms controlling endoderm formation by combining experimental (e.g., ChIPseq and RNAseq) and computational approaches. Production of a thorough endodermal gene regulatory network in frog will provide a useful framework for prediction, that is applicable to early mouse and human embryogenesis, thereby offering valuable knowledge to the broader scientific community for reprogramming stem cells along endodermal cell lineages.


BMP Signaling in Preimplantation Mammalian Development
Using quantitative imaging techniques and analyses, we map and quantitate the dynamic activities of BMP signaling activities in preimplantation mouse embryos and demonstrate for the first time the biological function and mechanism of BMP signaling in the preimplantation mammalian embryos. We show that BMP signaling regulates cell division and is critical for the establishment of mouse blastocysts. Our work will shed light on an issue of early pregnancy loss: failure of the blastocyst to undergo normal development.

Genome engineering using the CRISPR/Cas9
The CRISPR/Cas9 system relies upon the formation of double-stranded hybrids between synthetic guide RNA and genomic DNA and confers mutations in the genome. With Xenopus, the ability to microinject hundreds of synchronous, in vitro-fertilized embryos represents a significant advantage over other systems for examining mutations in the F0 generation. We use Xenopus tropicalis and develop methods to eliminate a large genomic region and induce a homologous recombination at a desired locus within the genome.
