ABSTRACT
Liver transplantation is a life-saving procedure, but it faces major obstacles—including the scarcity of donors and the need for immunosuppressive drugs. This study explored an alternative approach that uses a Thread-Reinforced Alginate Fiber for Islet enCapsulation (TRAFFIC) device to encapsulate liver cells in alginate hydrogels. Alginate cross-linked with calcium chloride (CaCl2) forms stable gels that protect cells from immune rejection. We adapted the TRAFFIC device for liver cells and applied solidified and non-solidified alginate gels to nylon threads. The experiments showed that the cells were successfully encapsulated, remained viable, and the gels stayed intact. Moreover, fluorescent staining confirmed that the cells inside were still alive even after encapsulation. Additionally, over a 40-day period, cell viability remained stable, as shown by fluorescent markers for live and dead cells. These results suggest that using alginate gel encapsulation for liver cells could become a promising approach to transplantation. In the future, this technology could potentially reduce the need for immunosuppressive drugs, although further refinement is needed.
