The C. elegans intestine: organogenesis, digestion, and physiology.

abstract：:During normal development of many vertebrate species, substantial numbers of neurons in the central and peripheral nervous system undergo naturally occurring (or programmed) cell death. For example, approximately 50% of spinal motoneurons degenerate and die at a time when these cells are establishing synaptic connecti...
