Extended Data Fig. 2: SEM showing the membrane protrusions of intratumoral NK cells from multiple cancers.
From: Tumors evade immune cytotoxicity by altering the surface topology of NK cells
a–c, SEM showing the membrane protrusions of the NK cells purified from resected tumors and outside the tumor of lung-cancer, colon-cancer, and ovarian-cancer patients. The mean number of membrane protrusions and the mean length of membrane protrusions in each sample are shown. Each dot represents one sample. n = 5 in each group. Data are the mean ± s.d. Scale bar, 1 μm. Data were analysed by two-tailed, unpaired Student’s t-tests.
