Uterine natural killer cells, implantation failure and recurrent miscarriage
Increased numbers of uNK cells have been associated with reproductive failure.
The number of preimplantation uNK cells has been reduced with prednisolone. However, despite these exciting advances in understanding of the uNK cells, considerably more work needs to be done to establish a specific role for uNK cells and to use uNK cells as a test of malfunctioning endometrium and the basis for future treatment for reproductive failure.
