I'm sure that they wouldn't do any human testing before animal trials.
Since this is "the first in vivo data," it probably refers to "in mice."
Specifically, Geron researchers probably transplanted human cells expressing
telomerase into some strain of immunocompromised mice, such as SCID mice or
nude mice. Technically, this would be *in vivo* expression of telomerase.
Since the immune systems of these mice could not reject the human cells, the
researchers could gather data about "cancer-associated physical and
