Mother Nature has provided the lizard with a unique ability to regrow body tissue that is damaged or torn ― if its tail is pulled off, it grows
right back. She has not been quite so generous with human beings. But we might be able to come close, thanks to new research from Tel Aviv University.
Prof. Meital Zilberman of TAU's Department of Biomedical Engineering has developed a new biologically active "scaffold" made from soluble fibers,
which may help humans replace lost or missing bone. With more research, she says, it could also serve as the basic technology for regenerating other
types of human tissues, including muscle, arteries, and skin.
"The bioactive agents that spur bone and tissue to regenerate are available to us. The problem is that no technology has been able to effectively
deliver them to the tissue surrounding that missing bone," says Prof. Zilberman. Her artificial and flexible scaffolding connects tissues together as
it releases growth-stimulating drugs to the place where new bone or tissue is needed ― like the scaffolding that surrounds an existing building when
additions to that building are made.
Scientific peer-reviewed research on this scaffold fiber has appeared in a number of journals, including Acta Biomaterialia, and is currently being
licensed through Ramot, TAU's technology transfer company.

It seems biochemistry is on the brink of another revolutionary medical breakthrough. Imagine what this could do for people who have lost limbs. . .
Between stem cell research and research along this avenue the medical future seems very promising indeed.

I thought extracellular matrix from pig bladders already did this. A 60 some year old guy regenerated the tip of his finger a couple years ago. Last
I heard the military was looking into it but I haven't heard any other successes since then which seems a bit odd...

the interesting part is that this ability (fingertip regeneration) exists in children but appears to be lost around the age of 10.
