Abstract

Despite remarkable progress in the clinical management of hepatocellular carcinoma (HCC), complications such as heterogenicity of HCC cells and characteristics of cancer stem cells (CSCs) contribute to frequent relapse and treatment resistance. Lack of proper in vitro models has limited developing novel approaches to evaluate innovative therapeutic settings to overcome these challenges. To address current limitations for mimicking cancer microenvironments; various three-dimensional (3D) platforms have been developed, such as tumoroids, patient-derived xenograft (PDX) models, microfluidics-based cancer chip devices, and bio-printed microtissues. Notably, 3D bio-printing technology has enabled researchers to produce scalable complex multicellular tissue models with accurate matrix composition and cellular organization. These microtissues provide precise platforms studying liver regeneration pathways, fibrosis reversal, and cellular responses to therapeutic interventions. This paper, a systematic literature search of databases covering publications from 2000 to 2025, uniquely highlights how these advances enable precise recapitulation of tumor heterogeneity and microenvironmental complexity, thereby offering transformative platforms for personalized drug screening and elucidating mechanisms of liver tissue repair and regeneration. We discussed current challenges and future directions for translating 3D bio-printed liver models into clinically relevant tools, potentially accelerating therapeutic advances and their potential applications in regenerative medicine in terms of personalized medicine and drug screening. © 2025 Informa UK Limited, trading as Taylor & Francis Group.
