In addition to regenerating tissue replacements, human stem cells and/or differentiated cells can serve as promising platforms for drug discovery and toxicity testing within the pharmaceutical industry.
TRAVEL Lab of the Human Clones It doesn't matter that a perfect "replacement" human can never be created.
Sitting in Ral's gleaming white office, it occurred to me that it doesn't really matter in the end that a perfect "replacement" human can never be created.
Coral skeletons can regenerate replacement human bone in nonload-bearing excavated skeletal locations.
Japanese stem cell biologist Hiromitsu Nakauchi is pioneering a technique that ultimately aims to implant human pluripotent cells into pig embryos to create replacement human tissues and organs.
Bred to grow replacement human organs — less morally controversial than clones, was the argument — the pigoons are large, tusked and seeded with human tissue that includes active brain matter, making them extraordinarily intelligent.
For the most part they are not replacements for humans; they are better seen as extensions.
The performance of this valve has been evaluated in vitro under simulated aortic conditions, as a pulmonary valve replacement in sheep, and in aortic and pulmonary valve replacement in humans.
Partly, though, it is because designing automated replacements for human tailors is hard.
Expert systems remain aids to, rather than replacements for, human experts.
