Roles for activator protein 2 (AP-2) transcription factors in zebrafish neural crest development

TL;DRAbstract

<p>Neural crest is a vertebrate-specific population of embryonic precursor cells thought to have been essential in vertebrate evolution. During development, a group of naïve ectoderm cells are induced to become neural crest and then undergo series of developmental events to give rise to diverse derivatives. Failure of these events often leads to malfunction of neural crest derived tissues and organs. This thesis focuses on the genetic regulation of two events during neural crest development, induction and differentiation.</p> <p>Neural crest induction refers to the specification of ectoderm cells to the neural crest lineage. It is believed that combinatorial activity of transcription factors governs neural crest induction, but the function of specific transcription factors in this process are not yet clear. The AP-2 family of transcription factors is implicated in control of neural crest development, but whether there is a cell autonomous role of AP-2 transcription fa
