Published Workflows

Objective: Develop and deploy animal-free hPSC culture platforms that are reproducible, safe, scalable, and suitable for drug discovery and predictive toxicology.

Why it works: The review describes a progression from poorly defined feeder-dependent and xenogeneic systems to defined and synthetic platforms, then further integration of automation, AI, and 3D bioprocessing to improve standardization, quality control, and throughput for downstream pharmaceutical use.

Stages

  1. 1.
    Transition to defined animal-free culture platforms(library_design)

    This stage exists to address long-standing reproducibility, safety, and translation problems associated with feeder-dependent and xenogeneic culture systems.

    Selection: Adopt chemically defined, xeno-free, and fully synthetic platforms instead of feeder-dependent and xenogeneic matrices.

  2. 2.
    Deploy defined substrate technologies for scalable GMP-compatible culture(functional_characterization)

    The review identifies these substrate classes as enabling scalable and GMP-oriented culture while reducing variability and immunogenic concerns.

    Selection: Use recombinant extracellular matrix proteins, synthetic peptide substrates, and polymer-based coatings that enable GMP-compliant scalable hPSC culture.

  3. 3.
    Integrate process technologies for standardization and throughput(secondary_characterization)

    The review presents these technologies as process-level enhancements after establishment of defined culture platforms.

    Selection: Add automation, AI, and 3D bioprocessing to enhance standardization, quality control, and throughput.

  4. 4.
    Apply hPSC-derived models in screening and toxicology(confirmatory_validation)

    The review frames pharmaceutical application as the downstream use case that benefits from improved culture platforms and process standardization.

    Selection: Use hPSC-derived cellular models in high-throughput drug screening and mechanistic toxicological assays.
