The resulting "chimeric" mice are composed partly of host cells and partly of the donor embryonic stem cells.
As long as some of the chimeric mice have germ cells (sperm or eggs) that have been derived from the embryonic stem cells, it is possible to breed a line of mice that have the same genetic constitution as the embryonic stem cells and therefore incorporate the genetic modification that was made in vitro.
The pièce de résistance here is a muscular wall work, the remnants of an action that the artist performed in the space using Olympic-grade weights; it relates to his upcoming film, "River of Fundament," which links subjects as various as Norman Mailer, Chrysler automobiles, the Egyptian gods Isis and Osiris, Harry Houdini, and the chimeric artist James Lee Byars.
If all this sounds like pure fantasy, bear in mind that in Dubai, in 2011, a "chimeric duck" was successfully engineered: it walked like a duck and quacked like a duck but was in fact a chicken, at least reproductively.
Words no longer seemed chimeric to Jack, no longer seemed approximations for something else.
Natural hearing tries hard to avoid chimeric percepts, but music often tries to create them.
Chimeric cells from fetuses appear to seek out damaged tissue and help heal it, for example.
The altered T-cells — called chimeric antigen receptor cells — are then dripped back into the patient's veins, and if all goes well they multiply and start destroying the cancer.
It involves adding gene sequences from different sources to enable the T-cells to produce what researchers call chimeric antigen receptors, or CARs — protein complexes that transform the cells into, in Dr. June's words, "serial killers".
Dr. Horowitz, the author of a best-selling book about dog cognition, "Inside of a Dog," belongs to a community of researchers paying ever closer attention to the nature of the human-animal bond in all its fetching dissonance, a pursuit recently accorded the chimeric title of anthrozoology.
Every so often he switched to guitar, an instrument Radian added on its 2009 album "Chimeric" (Thrill Jockey); he scraped the strings, dispensed stray chords or administered furious and exact bursts of tremolo strumming.
