This could soon pave the way for real, functioning organs.
Scientists are now desperately seeking government approval for the 2019 clinical trial.
It’s the 79th organ in the human body.
In a new study published in Nature, researchers have demonstrated a technique that allows the mapping of organs at microscopic scales.
Among all the species with which we share the animal kingdom, pigs are the ones whose organs are best suited for transplant in human bodies — they are approximately the same size as our organs and have similar structures, making reconnecting blood vessels much easier. Pigs tend to have large litters and reproduce quickly, making them a very large, very accessible source of “spare parts.”
Stem cells were coaxed to grow into 3D dimensional mini lungs, or organoids, for the first time. These survived for more than 100 days. These pioneering efforts will serve to deepen our understanding of how lungs grow, as well as prove very useful for testing new drugs’ responses to human tissue. Hopefully, once human tissue grown in the lab becomes closer and close to the real deal (cultured hearts, lungs, kidneys etc.), animal testing might become a thing of the past.
A new “organ on a chip” has been developed by Harvard researchers, reproducing the structure, functions, and cellular make-up of bone marrow, a complex tissue that until now, could only be studied on living animals. Bone marrow is one of the more complex and fragile parts of the human body – many drugs and toxic elements affect the bone marrow in
The latest in a long line of studies conducted on the fruit fly showed that organs have the molecular mechanisms to control their proportions, a process in which a protein called p53 plays the crucial role. The study was conducted by researchers at IRB Barcelona headed by ICREA Professor Marco Milán and will be published in December 15 in the
