This isn’t the first human-animal chimera to be created. In 2017, some of the same scientists created human-pig chimeras, by introducing human stem cells into pig embryos and incubated them in ...

Human chimera work could also shed new light on serious human developmental problems, and even be used to manufacture donor organs---if chimeric embryos are allowed to develop into fetuses.

A human lung in a pig might show more accurately the effect of a compound intended to treat, say, cystic fibrosis than today’s lab animals. Scientists not involved in the chimera experiment ...

But a U.S. and Chinese research team has just taken a huge step toward unlocking these previously unknowable secrets by developing robust monkey-human chimera (hybrids using genetic material from ...

In a sense, that’s what the team hopes human-animal hybrids will one day do. There are two ways to make a chimera. The first is to introduce the organs of one animal into another—a risky ...

A chimera is a hybrid of two species. In this case, scientists working on new possibilities for creating lab-grown organs for human transplants created early embryos that are half-human and half ...

Everything thus far falls under the category of “natural” chimeras, people who come by their dual DNA in the course of normal human development. But, later in life, a person can also become an ...
