Focus on cell biology and physiology in neuroscience and human organs with 14 years on academia and industry. Trained as neuroscientist with expertise on electrophysiology, iPSC, neural stem cells, in vitro cell models and animal behaviours, I now develop in vitro disease models for multiple organs, especially liver disease.Comparing the brain(and spinal cord) and the liver: 1) the brain neurons have limited regeneration capacity but the liver hepatocytes regenerate naturally.2) the brain have a tight and very selective brain-blood-barrier (blood-spinal cord barrier) that control the exchange between the brain and the blood. But the liver is to welcome to most of the blood intent. The estimated pore size on the endothelial cells in the BBB may be around 20 nm, one per 200 microns2(*1*) ; the pore size of the liver endothelial cell can be 50–300 nm in diameter (*2*).3) The primary livers cells are popular and important for toxicity and metabolism test in the industry, but the primary brain cells are rare. 4) A lot more to learn!We focus on the primary liver cells and related products, iPSC-derived liver products and downstream applications.
