In a scientific “first,” a tiny heart structure composed of human cells has been successfully grown within a pig embryo.

The pig’s mouth revealed its ordinary sharp, tusk-like canines saddled up beside smaller, slightly more human-looking teeth nubs. In theory, a similar process could play out in humans.

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.

Scientists grew human-like teeth in pigs. Here's how and why Tufts University researchers took material from human and pig teeth and were able to grow a tooth-like structure.

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.
