Project description:To investigate global changes of miRNA profiles upon differentiation of human neural stem cells, we applied massively parallel sequencing (MPS) technology to an immortalized neural stem cell (HB1.F3) and its differentiated cell (F3.Olig2) lines. We identified 339 known miRNAs, out of which 170 miRNAs are up-regulated in F3.Olig2, while only 59 miRNAs in HB1.F3. We also identified 150 novel miRNA candidates.

Project description:Neural stem cells (NSC) with self-renewal and multipotent properties serve as an ideal cell source for transplantation to treat spinal cord injury, stroke, and neurodegenerative diseases. To efficiently induce neuronal lineage cells from NSC for neuron replacement therapy, we should clarify the intrinsic genetic programs involved in a time and place-specific regulation of human NSC differentiation. Recently, we established an immortalized human NSC clone HB1.F3 to provide an unlimited NSC source applicable to genetic manipulation for cell-based therapy. To investigate a role of neurogenin 1 (Ngn1), a proneural basic helix-loop-helix (bHLH) transcription factor, in human NSC differentiation, we established a clone derived from F3 stably overexpressing Ngn1. Genome-wide gene expression profiling identified 250 upregulated genes and 338 downregulated genes in Ngn1-overexpressing F3 cells (F3-Ngn1) versus wild-type F3 cells (F3-WT). Notably, leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5), a novel stem cell marker, showed a robust increase in F3-Ngn1.
