However, the NASH model did produce slightly lower amounts of albumin (Supporting Fig. S2), matching observations from the clinic, where reduced albumin correlates with advanced liver disease.28, 29, 30 PHHs in the MPS form microtissues within the 3D collagen‐coated scaffold, and to visualize the distribution of HKs and HSCs within these microtissues, each cell type was transduced with an adenovirus expressing a fluorescent marker (Supporting Fig. S3). The gene discussed is ALB; the disease is metabolic dysfunction-associated steatohepatitis.
