Studies to identify genes relevant to mammalian hepatocyte biology in vivo are largely carried out using germline genetic-engineering approaches, which can be costly and time-consuming. We describe hydrodynamic tail vein injection as an alternative approach to introduce genetic elements into hepatocytes. Transfected hepatocytes can then be traced with a GFP reporter enabling the use of immunohistochemistry and FACS sorting to examine the changes in hepatocyte gene expression and proliferation during liver regeneration induced by 2/3 partial hepatectomy (PH). For complete details on the use and execution of this protocol, please refer to Wang et al. (2019).
