Fascinating Things Grown In A Lab

There is no doubt that science has made incredible breakthroughs in the past 100 years. This is especially true in medicine and biological engineering. From lifesaving vaccines to revolutionary surgeries, science has vastly improved our quality of life. Progress requires researchers to innovate new solutions to age-old problems. Behind every medical discovery, there’s a laboratory full of […]

Brain Balls

Only about 4 millimeters (0.16 in) in diameter, this small clump of human brain tissue was grown in the lab from stem cells. With the right hormones, researchers can coax the tissue to […]

Rabbit

The males had all been given lab-grown penises, an idea he’d been working on since 1992. Of the 12 rabbits given bioengineered penises, all of them attempted mating. […]

Apple Ears

Using a decellularization technique to remove existing cells from the apple, they were left with the apple’s cellulose “scaffolding.” By the way, that cellulose is what gives apples their satisfying crunch.[7] Pelling and his […]

Blood Stem Cells

This group started with human skin cells and “reprogrammed” them to become iPS (induced pluripotent stem) cells. An iPS cell is an artificially made, universal stem cell. Daley’s […]

Mouse Sperm

To do this, they extracted stem cells from mice and introduced them to testicular cells from newborn mice. Qi Zhou and Xiao-Yang Zhao, who led the experiment, also exposed the stem cells to several […]

Hamburgers

His goal was to produce meat that didn’t cause “undue animal suffering and environmental harm” as traditional meat sources do. The project took him five years and $325,000 […]

Pig Bones

Quite the opposite. The blood vessels inside the lab-grown bones seamlessly integrated themselves into the pigs’ preexisting circulatory systems. How was all of this possible?[1] To get […]
