A mouse embryo injected with cells made pluripotent through stress?

Does "A mouse embryo injected with cells made pluripotent through stress, tagged with a fluorescent protein" mean "(Scientist) first make cells pluripotent by stress, and then injected the cells into a mouse embryo, and the cells were tagged/marked by a fluorescent protein"?

Context:

A mouse embryo injected with cells made pluripotent through stress, tagged with a fluorescent protein.
In 2006, Japanese researchers reported1 a technique for creating cells that have the embryonic ability to turn into almost any cell type in the mammalian body — the now-famous induced pluripotent stem (iPS) cells. In papers published this week in Nature2, 3, another Japanese team says that it has come up with a surprisingly simple method — exposure to stress, including a low pH — that can make cells that are even more malleable than iPS cells, and do it faster and more efficiently.
