WebFeb 8, 2002 · Introduction. The field of tissue engineering exploits living cells in a variety of ways to restore, maintain, or enhance tissues and organs ( 1, 2 ). Tissue engineering conjures up visions of organs built from scratch in the laboratory, ready to be transplanted into desperately ill patients. The potential impact of this field, however, is far ... WebJul 17, 2024 · The new technique relies on an approach known as expansion microscopy, developed originally in Edward Boyden’s lab at MIT, in which the researchers expand a tissue sample to 100 times its original volume before imaging it. This expansion allows researchers to see features with a conventional light microscope that ordinarily could be …
