Bridging Mechanical Precision and Life Sciences

Cellknit Inc. is a pioneering bio-venture rooted in POSTECH’s advanced mechanical engineering research. We specialize in next-generation cell delivery platforms that ensure the highest level of biological integration and mechanical integrity.

The Era of "Cell" as Medicine

Current Limitation

High cell loss during delivery and low engraftment rates have been the major bottleneck in cell therapy commercialization.

Our Solution

Cellknit provides a revolutionary micro-mechanical environment that mimics natural tissue, ensuring maximum cell survival and integration.

Threadrix™ Technology

Threadrix™ utilizes a hierarchical multi-strand integrated architecture of junction-free nanofiber bundles, mimicking the tissue-scale complexity of natural ECM for superior cell protection and tissue integration.

Core Features

Junction-free Architecture

Our junction-free nanofiber network maintains stable micro-pore structures, protecting loaded cells from external mechanical stress while ensuring structural flexibility.

Gradual Modulus Control

Tailored mechanical properties with gradual modulus transitions, optimized for multi-tissue interfaces such as the bone-tendon junction.

Biomimetic ECM

Advanced mineralization and structural design that mimics the Extracellular Matrix (ECM) for seamless in-vivo integration and minimal inflammatory response.
