A More Accessible Drosophila Genome to Study Fly CNS Development: A Dissertation
TL;DRAbstract
Understanding the complex mechanisms to assemble a functional brain demands sophisticated experimental designs. Drosophila melanogaster, a model organism equipped with powerful genetic tools and evolutionarily conserved developmental programs, is ideal for such mechanistic studies. Valuable insights were learned from research in Drosophila ventral nerve cord, such as spatial patterning, temporal coding, and lineage diversification. However, the blueprint of Drosophila cerebrum development remains largely unknown. Neural progenitor cells, called neuroblasts (NBs), serially and stereotypically produce neurons and glia in the Drosophila cerebrum. Neuroblasts inherit specific sets of early patterning genes, which likely determine their individual identities when neuroblasts delaminate from neuroectoderm. Unique neuroblasts may hence acquire the abilities to differentially interpret the temporal codes and deposit characteristic progeny lineages. We believe resolving this age-old speculation
