Scientists tracked how human immune cells attack pig kidneys after transplant—and found a way to fight back using precision ...

Scientists have achieved an unprecedented look into how the human immune system attacks a transplanted pig kidney, using spatial molecular imaging to map immune activity down to the cellular level.

But there's a problem, and a big one at that: The body naturally wants to reject any tissue it knows it didn't manufacture.
