| The ability of natural killer (NK) cells to destroy cancerous cells with no prior sensitization has made them attractive candidates for cell therapy. The application of hydrogels must be notified as cell delivery vehicles in cell differentiation. The present study was conducted to investigate the effect of alginate-gelatin encapsulation on NK
cell differentiation potential of C-kit+ cells. C-kit+ cells were differentiated to NK cells under both encapsulated
and un-encapsulated conditions. Next, the cells were subjected to real-time polymerase chain reaction (PCR) and
western blotting for the assessment of their telomere length and protein expressions, respectively. Afterward,
culture medium was collected to measure cytokines levels. Thereafter, the differentiated NK cells were cocultured with Molt-4 cells to investigate the potency of cell apoptosis by Annexin V/PI assay. A significant change
was observed in the protein expression of Janus kinase/Signal transducers (JAK/STAT) pathway components. Additionally, the encapsulation caused an increase in the apoptosis of Molt-4 cells and telomere length of NK cells
differentiated C-kit+ cells. Therefore, it can be concluded that the effects of encapsulation on NK cell's differentiation of C-kit+ cells could be resulted from the secreted cytokines of interleukin (IL)-2, IL-3, IL-7, and IL-12 as well
as the increased telomere length. |
