Genetically Modified Cells TRIZ Cases
- Antigen-Presenting Cell Electroporation for T-Cell Activation
Electroporation introduces mRNA encoding immunostimulatory factors into antigen-presenting cells to overcome T-cell tolerance from complex manipulation.
- NK Cells Engineered to Eliminate Cbl-b for Enhanced Tumor Targeting
Eliminating Cbl-b in NK cells maintains tumor-targeting capabilities during expansion, resolving the trade-off between cell quantity and functional reliability.
- CCR8-Engineered Lymphocytes for Tumor Infiltration
Engineering lymphocytes with CCR8 receptors directs cells toward CCL1 gradients, overcoming poor infiltration in adoptive cell therapy.
- Humanized Mouse Models for Porcine Xenoreactivity Testing
Humanized mouse models replace non-human primates to accelerate preclinical trials while maintaining immune response representativeness.
- Ex Vivo Microbiopsy Reprogramming for Scarless Tissue Regeneration
iTR factors revert cells to an embryonic-like state, enabling ex vivo expansion and scarless wound healing without teratoma risks.
- High Choline Chloride Cell Culture Medium for Fed-Batch Polypeptide Production
A cell culture medium with high choline chloride content supports viable cell densities and polypeptide titers in fed-batch processes.
- Inducible Expression Vectors for Stable Mammalian Protein Production
PiggyBac transposon vectors with inducible promoters enable high-titer antibody production while preventing metabolic burden during cell growth.
- Immortalized Sweat Gland Myoepithelial Cell Production
Suspended culture of sweat gland myoepithelial cells with viral vectors produces immortalized cells expressing alpha-SMA and pan-cytokeratin.
- Podocyte Culture Method for Homogeneous High-Throughput Screening
Switching culture conditions between permissive and non-permissive states resolves the contradiction between cell proliferation and morphological homogeneity.
- Dipeptide Culture Medium for Glutamine Stability
Asparagine-glutamine dipeptides stabilize glutamine during heat sterilization, resolving instability issues in cell culture media.
- Modified Protein G Peptide for Fab Region Binding
Engineered protein G variants with optimized amino acid sequences capture antibody fragments lacking Fc regions, enabling efficient purification.
- Transdifferentiating Non-Dermal Papilla Cells to Induced Dermal Papilla Cells
A dermal papilla cell reprogramming system transdifferentiates non-dermal papilla cells into induced dermal papilla cells.
- Inducible Pluripotent Stem Cell Derived Veto Cells for Transplant Tolerance
Veto cells derived from gene-edited pluripotent stem cells induce donor-specific immunological tolerance.
