Internship description: Stem cells produce all cells from our organism during development and persist in most adult tissues to replace dying cells. This is also true for the central system, where they are named “neural stem cells, or NSCs”. These NSCs produce different cell types depending on their location (spatial identity), and their age (temporal identity). For example, NSCs located in the dorsal most regions of the developing brain produce the excitatory neurons of our cortex during early embryonic development, then switch to producing glial cells at later stages.

The transcriptional coding of NSCs’ spatial and temporal identity is starting to be unravelled. Several laboratories, including our, have recently performed single cell and bulk RNA-Seq of progenitors isolated from different location and at different times. The intern will bring skills and creativity in bioinformatics and statistics to integrate and compare these datasets. In particular, several key biological questions will be addressed using bioinformatics tools such as tSNE clustering, minimum spanning tree, etc... :

  • Are distinct NSCs populations observed at early and late developmental timepoints?
  • Are distinct NSCs biased towards a neuronal or glial fate observed at late developmental times?
  • Are progenitors present in the adult brain distinct from those active during development?
