  Our laboratory studies what mechanisms control stem cells to become neurons for repairing neurodegenerative diseases and how to generate induced neuronal (iN) cells. There are several ongoing projects in our lab.

  1. Studying the mechanisms involving neural stem cell proliferation and neurogenesis During mammalian embryonic brain development, the generation of three major neural cell types (neuron, astrocyte and oliogodentryocyte) from neural stem cell follows an evolutionarily conserved temporal and spatial sequence. Neurogenesis precedes gliogenesis throughout the central nervous system (CNS). Both cell intrinsic factors and extracellular cues have been postulated to influence the neurogenic to gliogenic switch. We will use several strategies to identify what signaling molecules that control this process. We are also interested in studying what mechanisms control adult neural stem cell proliferation and neurogenesis.

  2. Generating induced neuronal cells The direct conversion of somatic mouse fibroblasts to induced neuronal cells has been reported by transfection of neuronal specific transcription factors. We aim to generate iN cells from fibroblasts using non-integration adenovirus system and find whether other transcription factors can be used to convert fibroblasts to neurons with high efficiency.

Studying trans-differentiation from fibroblasts to neurons

Studying epigenetic molecules in neural stem cell and neurogenesis


Plain English:
  Our laboratory focuses on studying what mechanisms and signaling pathways control stem cell proliferation and neurogenesis. Identification of neuron-specific genes or miRNAs from neural stem cells is the direction of this study. There are several research directions including what mechanisms involving neural stem cell proliferation and neurogenesis and how to convert fibroblasts to neurons.
