Abstract
Our lab is focused on the highly conserved second exon of Col2a1a utilized during embryogenesis. Within this second exon is the von Willebrand Factor Type C (VWF-C) domain, which regulates the production of Bone Morphogenic Proteins (BMPs). BMPs are essential growth factors that signal the development of cartilage, heart, bone, and neural tissue formation. Using CRISPR-Cas9 we will splice out exon 2 (subsequently knocking out the VWF-C domain) to observe the change in BMP production and its effect on the growth and development of zebrafish embryos. Given the role the VWF-C domain plays in BMP production, we expect that the removal of exon 2 of Col2a1a will severely impact the zebrafish embryonic development, characterized by developmental delays, abnormal morphology, and possible embryonic lethality.
