Dissertations and Theses @ UNI

Congenital heart defects are one of the leading causes of infant death. High maternal blood serum levels of the amino acid homocysteine and the frequency of heart defects are correlated, but the immediate cause is unknown. During early embryonic development, a distinctive population of cells arises dorsally as the neural tube closes, forming the brain and spinal cord. These are the neural crest cells, which play a crucial role in the development of the nervous system, head skeletal, certain endocrine and connective tissues, and, notably, the heart’s outflow region. These migratory cells will follow specific pathways and respond to signals …
