    ANIMAL & CELL MODELS
    In homozygous Adk -/- mice, embryonic stem cells developed normally during embryogenesis. However, within 4 days after birth they displayed microvesicular hepatic steatosis and died within 14 days with fatty liver. Thus, a deficiency of adenosine metabolism is identified as a powerful contributor to the development of neonatal hepatic steatosis, providing a model for the rapid development of postnatally lethal fatty liver (Boison 2002)
