Metabolic lactate production coordinates vasculature development and progenitor behavior in the developing mouse neocortex

ABSTRACT: Proper neural progenitor behavior in conjunction with orderly vasculature formation is fundamental to the development of the neocortex. However, the mechanisms coordinating neural progenitor behavior and vessel growth remain largely elusive. Here we show that robust metabolic production of lactate by radial glial progenitors (RGPs) co-regulates vascular development and RGP division behavior in the developing mouse neocortex. RGPs undergo a highly organized lineage progression program to produce diverse neural progeny. Systematic single cell metabolic state analysis revealed that RGPs and their progeny exhibit distinct metabolic features associated with specific cell types and lineage progression statuses. Symmetrically dividing, proliferative RGPs preferentially express a cohort of genes that support glucose uptake and anaerobic glycolysis. Consequently, they consume glucose in anaerobic metabolism and produce a high level of lactate, which promotes vessel growth. Moreover, lactate production enhances RGP proliferation by maintaining mitochondrial length. Together, these results suggest that specific metabolic states and metabolites coordinately regulate vasculature formation and progenitor behavior in neocortical development.

Tissue-wide Genetic and Cellular Landscape Instructs the Execution of Sequential PRC2 Functions in Neural Stem Cell Lineage Progression [neurons]

Project description:The generation of a correctly-sized cerebral cortex with all-embracing neuronal and glial cell-type diversity critically depends on faithful radial glial progenitor (RGP) cell proliferation/differentiation programs. Temporal RGP lineage progression is regulated by Polycomb Repressive Complex 2 (PRC2) and loss of PRC2 activity results in severe neurogenesis defects and microcephaly. How PRC2-dependent gene expression instructs RGP lineage progression is unknown. Here we utilize Mosaic Analysis with Double Markers (MADM)-based single cell technology and demonstrate that PRC2 is not cell-autonomously required in neurogenic RGPs but rather acts at the global tissue-wide level. Conversely, cortical astrocyte production and maturation is cell-autonomously controlled by PRC2-dependent transcriptional regulation. We thus reveal highly distinct and sequential PRC2 functions in RGP lineage progression that are dependent on complex interplays between intrinsic and tissue-wide mechanisms. In a broader context our results imply a critical role for the genetic and cellular niche environment in neural stem cell behavior.

Multipotent Progenitors Instruct Ontogeny of the Superior Colliculus – MADM-CloneSeq E12

Project description:The superior colliculus (SC) in the mammalian midbrain is essential for multisensory integration and is composed of a rich diversity of excitatory and inhibitory neurons and glia. The developmental principles directing the generation of SC cell-type diversity are however not understood. Here we pursued systematic cell lineage tracing in silico and in vivo, preserving full spatial information, using genetic MADM (Mosaic Analysis with Double Markers)-based clonal analysis with single-cell sequencing (MADM-CloneSeq). The analysis of clonally-related cell lineages revealed that radial glial progenitor (RGP) cells in SC are exceptionally multipotent. Individual resident RGPs have the capacity to produce all excitatory and inhibitory SC neuron types, even at the stage of terminal division. While individual clonal units show no pre-defined cellular composition, the establishment of appropriate relative proportions of distinct neuronal types occurs in a PTEN-dependent manner. Collectively, our findings provide an inaugural framework at single RGP/cell level of the mammalian SC ontogeny

A brain precursor atlas reveals the acquisition of developmental-like states in adult cerebral tumours

Project description:We map the development of mouse cerebrum across the developmental time-course, from embryonic day 12.5 to postnatal day 365, performing single-cell transcriptomics on >100,000 cells. By comparing this reference atlas to single-cell data from >100 glial tumours of the adult and pediatric human cerebrum, we find that tumour cells have an expression signature that overlaps with temporally restricted, embryonic radial glial precursors (RGPs) and their immediate sublineages. Further, we demonstrate that transformation of early RGPs in a genetic mouse model gives rise to adult cerebral tumours that show an embryonic/juvenile RGP identity. Together, these findings implicate the acquisition of embryonic-like states in the genesis of adult glioma, providing insight into the origins of human glioma, and identifying specific developmental cell types for therapeutic targeting.
