Document Summary
1: neural proliferation, migration and aggregation, axon growth and synapse formation, neuron death/synapse reformation and rearrangement. Totipotent fertilized egg can develop into any class of cell. After 4 days of embryological development, cells lose their totipotency o. Unipotent can only develop into one class/type of cell. Neural plate is the first of all vertebral plates: mesoderm the organizer, dorsal mesoderm taken from one embryo and planted beneath the ventral ectoderm of another i. Pluripotent (when np develops to nt fate becomes more specified) Why is there unlimited capacity for self renewal: when a stem cell divides, 2 daughter cells are created, one develops into a body cell, the other into a stem cell o. Therapeutic potential of these cells is under active investigation. Anterior end of the neural tube three swellings: forebrain, midbrain, hindbrain. Failed closure of the caudal neuropore= spinal bifida. Cells of the neural tube are developed, migration to the proper location.
