Usefulness & Problems

Published Workflows

Objective: Couple nuclear and mitochondrial editing with maturation strategies to produce metabolically competent, structurally mature iPSC-CMs with more adult-like phenotypes.

Why it works: The abstract argues that mitochondrial immaturity is the key bottleneck in iPSC-CMs, so combining genome-guided activation/editing with environmental maturation cues is expected to better restore mitochondrial biogenesis, oxidative metabolism, and adult-like phenotypes.

Stages

  1. 1.
    Genome-guided intervention selection(library_design)

    The review centers the workflow on mitochondrial immaturity and therefore first identifies nuclear regulators and mitochondrial editing tools that can directly modulate this bottleneck.

    Selection: Target key regulators of mitochondrial biogenesis and select genome-guided tools including CRISPR-based transcriptional activators/repressors and mtDNA editors.

  2. 2.
    Genome-guided mitochondrial enhancement(functional_characterization)

    This stage tests whether genome-guided interventions improve core mitochondrial properties identified as limiting iPSC-CM maturity.

    Selection: Apply CRISPRa-mediated activation and mtDNA base editing to enhance mitochondrial mass and OXPHOS function.

  3. 3.
    Integration with environmental maturation cues(secondary_characterization)

    The abstract states that integration with environmental maturation strategies further promotes adult-like phenotypes beyond genome-guided interventions alone.

    Selection: Combine genome-guided interventions with metabolic conditioning, electromechanical stimulation, 3D tissue culture, or EV-mediated mitochondrial transfer.

  4. 4.
    Translational validation and standardization considerations(confirmatory_validation)

    The abstract explicitly identifies these issues as remaining translational challenges that must be addressed for practical deployment.

    Selection: Assess remaining translational challenges including efficient mitochondrial delivery, metabolic homeostasis, and multi-omics validation.
