The effects of encapsulation on NK cell differentiation potency of C-kit plus hematopoietic stem cells via identifying cytokine profiles

Natural killer cells (NK cells) can kill cancerous cells without prior sensitization. This feature makes them appealing candidates for cellular therapy. Due to the degradation rate and controlled release of these matrices, hydrogels hold great promise in cell differentiation. The study aims to investigate the effect of encapsulated alginate-gelatin on the differentiation potential of C-kit+ cells toward NK cells which are mediated by cytokines detection. Under both encapsulated and unencapsulated conditions, C-kit+ cells can differentiate into NK cells. In the following, real-time PCR and western blotting were done to investigate the mRNA and protein expression, respectively. Determine cytokine profiles from the collected culture medium conducted a Cytokine antibody array. The differentiated cells were then co-cultured with Molt-4 cells to examine the expression levels of INF-gamma, TNF-alpha, and IL-10 using real-time-PCR. There was a substantial change in protein expression of the Notch pathway. Also, the encapsulation increased the mRNA expression of INF-gamma and TNF-alpha in Molt-4 cells. Based on these findings, the encapsulation effects on the differentiation of C-kit+ cells toward NK cells could be related to the secreted cytokines such as interleukin-10 and INF-gamma and the Notch protein expression.
