Functional diversification of Dicer-like proteins and small RNAs required for genome sculpting.

abstract：:Although many features of neurogenesis during development and in the adult are intrinsic to the neurogenic cells themselves, the role of the microenvironment is irrefutable. The neurogenic niche is a melting pot of cells and factors that influence CNS development. How do the diverse elements assemble and when? How doe...
