Nk cells freeze thaw
WebbTo develop a readily available, off-the-shelf cellular product, it is essential that NK cells differentiated in vitro can be frozen and thawed while maintaining the same phenotype … WebbNK cell therapy. Natural killer cells, discovered in the early 1970’s, represent only 5% to 20% of peripheral blood mononuclear cells (PBMCs; 1). Natural killer cells are phenotypically defined through the absence of CD3 expression and presence of CD56 (2, 3). Part of the innate immune system, NK cells efficiently kill a variety of malignant ...
