Kopcow et al. compared human natural killer cells from the decidua basalis of gravid uteri and from cycling endometrium of women undergoing hysterectomy by gene expression profiling. Decidual natural killer cells were isolated from the decidua basalis of first trimester placentas and FACS sorted as CD3-, CD16-, CD56+ cells. Endometrial natural killer cells were obtained from non-affected regions of cycling endometrium of donor women undergoing hysterectomy and FACS sorted as CD45+, CD56+, CD3- cells.
