Outline

This paper presents the Vision Transformer Digital Twin Surrogate Network (VT-DTSN), a deep learning framework for predictive modeling of 3D+T imaging data of biological tissues. Leveraging pre-trained Vision Transformers with Self-Distillation with No Labels (DINO) and a multi-view fusion strategy, we reconstruct high-fidelity, time-resolved dynamics of the Drosophila midgut. Trained with a composite loss function that prioritizes pixel-level accuracy, perceptual structure, and feature-space alignment, the network produces biologically meaningful results, making it suitable for in silico experiments and hypothesis testing. Evaluation across multiple layers and biological replicates yields low error rates and high structural similarity, enabling efficient inference. VT-DTSN serves as a high-fidelity surrogate model for cross-time reconstruction and tissue dynamics studies, enabling computational exploration of cellular behavior and homeostasis, complementing time-resolved imaging studies in biological research.

Takeaways, Limitations

Takeaways:
Enables high-fidelity, time-resolved predictive modeling of 3D+T imaging data of biological tissues such as the Drosophila midgut.
A novel deep learning framework (VT-DTSN) based on Vision Transformer utilizing DINO is presented.
Providing biologically meaningful results for in silico experiments and hypothesis testing.
Providing computational exploration tools to complement time-resolved imaging studies.
Ensuring practicality through model optimization for efficient inference.
Limitations:
Currently, modeling is limited to the Drosophila midgut. Further research is needed to determine generalizability to other tissues or species.
Model performance can depend on the quality of the training data. Difficulties arise in data acquisition and preprocessing.
There is a possibility that the model may not perfectly reflect complex biological processes. Further research is needed to determine the model's interpretability and reliability.
