SLCO1B3 and liver disorder: Considering that some liver diseases, as well as infections, have shown zonal preference (Caldwell and Argo, 2010; Zhuang et al., 2020; Manco and Itzkovitz, 2021; Yang et al., 2021), we expect that enriched PHHs (potentially further sorted based on zonal cell surface markers, for which SLCO1B3 could be a candidate) would serve as a better and more precise resource for pericentral liver disease modeling.
