Efficiently and with low toxicity, delivering functional molecules (such as CAR genes, TCR sequences, and cytokine mRNA) into immune cells or stem cells to achieve gene editing or transient modification, overcoming the limitations of traditional viral vectors.
Targeted Drug Delivery for Cell Therapy
Cell therapy is the future of precision medicine. Success requires safe cell engineering and precise cell behavior control in vivo. Targeted delivery is the core driver. Creative Biolabs provides advanced non-viral and biomimetic delivery systems for enhanced manufacturing efficiency and superior in vivo efficacy, solving toxicity and poor tumor penetration.
What is Targeted Delivery?
In the field of cell therapy, targeted delivery has a unique dual meaning, focusing on both the initial cell preparation and the final therapeutic action:
Molecular Engineering of Targeted Cells (Ex Vivo)
In Vivo Homing & Tracking (In Situ)
By engineering the cell membrane surface (e.g., homing peptides), we enhance the specific migration and retention of reinfused cells at the lesion site, while simultaneously using delivery systems for in vivo cell tracking and monitoring therapeutic effect.
Applications for Cell Therapy
Immuno-Cell Engineering
- CAR/TCR Cell Therapy: Providing optimized non-viral gene delivery solutions for T cells, NK cells, macrophages, etc.
- TILs Expansion and Modification: Enhancing the in vitro expansion efficiency and in vivo activity of tumor-infiltrating lymphocytes.
Stem Cells & Regenerative Medicine
- Stem Cell Modification: Safely and efficiently transfecting stem cells for gene correction, enhanced differentiation, or tissue repair.
Enhanced In Vivo Cellular Function
Delivery of mRNA or siRNA transiently modulates cytokine expression to enhance cellular antitumor activity, in vivo survival, or resistance to immunosuppression.

Delivery Challenges in Cell Therapy
Non-viral Gene Delivery Efficiency and Cell Viability In Vivo Cell Homing and Functional Durability Immunogenicity Control of Allogeneic Cells Cost & Accessibility
Traditional electroporation or viral vectors carry risks of high cost, induction of cell death, or random integration. The challenge is achieving high gene transfection efficiency with high viability, which is essential for manufacturing robust cellular products.
What We Can Offer
We offer professional delivery technologies, providing safe, efficient, and scalable engineering tools for your cell therapy projects:
Non-viral Gene Modification Platform
Optimized LNP/polymer nanocarriers, specifically designed for immune and stem cell transfection, ensuring efficient delivery of CAR/TCR mRNA or plasmid DNA with low cytotoxicity. This platform guarantees high cell viability and rapid, scalable ex vivo cell manufacturing, essential for commercial readiness.
Cell Surface Engineering and Homing
Providing advanced cell membrane modification technologies to load targeted ligands (such as chemokine receptor agonists, homing peptides, or biomimetic EV surfaces) onto the cell membrane. This strategy significantly enhances the cell's specific migration and retention in difficult environments like solid tumors or chronic inflammation sites.
Transient Regulation of Cellular Function
Delivering mRNA-encoded cytokines or next-generation gene-editing tools (such as transient CRISPR/Cas9 mRNA) to achieve precise, time-bound regulation of cellular function or phenotype. This allows for conditional activation, enhanced anti-tumor activity, and reduced systemic toxicity when the cell is outside the target area.
