Yet current efforts often emphasize model scale, data volume, or predictive breadth, while the trustworthiness required for scientific and translational use remains insufficiently addressed. We argue that virtual-cell models become decision-relevant only when the evidential chain connecting data, model design, benchmarking, and experimental validation is made explicit. We introduce the trustworthy virtual cell, a perturbation-resolved, context-aware, and experimentally validated system capable of supporting biological inference, experimental design, and preclinical decision-making. We organize recent progress around four empirical layers, namely, molecular cell state, intervention, biological context, and orthogonal phenotype, complemented by structured priors. This framework explains why static atlases, transcriptome-only readouts, and in-distribution benchmarks are insufficient for predicting cellular behavior under new conditions. Across mechanistic, deep generative, foundation, and hybrid models, we discuss trade-offs among interpretability, scalability, and extrapolation. We further argue that evaluation should move beyond held-out reconstruction accuracy toward biologically meaningful criteria, including generalization to unseen cell types and perturbations, dose, time, and combination response extrapolation, uncertainty calibration, and mechanistic consistency. We then propose a closed-loop validation ladder connecting\n                    <jats:italic>in silico<\/jats:italic>\n                    predictions to CRISPR perturbation, imaging, organoid, and tissue-level assays. Our aim is to review what current models can and cannot yet do, and to set out an evidential framework specifying what a virtual cell must demonstrate before its outputs are acted upon, noting which requirements are attainable today and which remain longer-term goals.\n                  <\/jats:p>","DOI":"10.3389\/fcell.2026.1900624","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T10:34:32Z","timestamp":1788863672000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Toward trustworthy virtual cells: a roadmap for perturbation-resolved, context-aware, and experimentally validated cell models"],"prefix":"10.3389","volume":"14","author":[{"given":"Wangshu","family":"Li","sequence":"first","affiliation":[{"name":"Key Laboratory of Biotherapy, Dalian Women and Children\u2019s Medical Center Group, Women and Children\u2019s Hospital Affiliated to Dalian University of Technology","place":["Dalian, Liaoning, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aziz Ur Rehman","family":"Aziz","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biotherapy, Dalian Women and Children\u2019s Medical Center Group, Women and Children\u2019s Hospital Affiliated to Dalian University of Technology","place":["Dalian, Liaoning, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bowen","family":"Xu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biotherapy, Dalian Women and Children\u2019s Medical Center Group, Women and Children\u2019s Hospital Affiliated to Dalian University of Technology","place":["Dalian, Liaoning, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingshan","family":"Xu","sequence":"additional","affiliation":[{"name":"Bengbu Medical University","place":["Bengbu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohui","family":"Yu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biotherapy, Dalian Women and Children\u2019s Medical Center Group, Women and Children\u2019s Hospital Affiliated to Dalian University of Technology","place":["Dalian, Liaoning, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daqing","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biotherapy, Dalian Women and Children\u2019s Medical Center Group, Women and Children\u2019s Hospital Affiliated to Dalian University of Technology","place":["Dalian, Liaoning, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunfang","family":"Ha","sequence":"additional","affiliation":[{"name":"General Hospital of Ningxia Medical University","place":["Yinchuan, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,8]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1867","DOI":"10.1016\/j.cell.2016.11.048","article-title":"A multiplexed single-cell CRISPR screening platform enables systematic dissection of the unfolded protein response","volume":"167","author":"Adamson","year":"2016","journal-title":"Cell."},{"key":"B2","doi-asserted-by":"publisher","first-page":"1657","DOI":"10.1038\/s41592-025-02772-6","article-title":"Deep-learning-based gene perturbation effect prediction does not yet outperform simple linear baselines","volume":"22","author":"Ahlmann-Eltze","year":"2025","journal-title":"Nat.
