NK cell different receptors mRNA expressing in subcutaneously transplanted tumor of mouse.

<p>NKG2D expression level of NK cells in high-metastasis L9981 group was significantly higher than that in low-metastasis NL9980 group (<i>p</i> = 0.018), and the Ly49I expression level of NK cells in L9981 group was also remarkably higher than NL9980 group (<i>p</i> = 0.001). No significant difference of the NK1.1 and NKG2A expression level of NK cells was existed between high and low metastasis group.
