ALB and cyst: The quantitative result that showed the upregulation of hepatocyte membrane transporters (Figure 2(a)) in 3D cysts included organic anion transmembrane transport 2 (Oatp2) (also known as Slco1b1), peptide transporter 1 (Pept1) (also known as Slc15a1), multidrug resistance-associated protein 2 (Mrp2) also known as Abcc2), the bile salt export pump (Bsep) (also known as Abcb11), and Albumin (Alb) (Figure 2(d)), indicating hepatic characteristics of 3D cyst.
