Scientists managed to create in the laboratory human bone from stem cell!
This evolutionary method makes fractures repaired or even replaced entirely
problematic bones with artificial limbs, coming essentially from
the patient's body.

| Human bone in the laboratory, created by patient's stem cells. |
In particular, researchers from Technion Institute of Technology in Israel
began their experiments on stem cells taken
from fat tissue, and within a
month’s time developed complete bone-shaped,
approximately five centimeters.
The first test will be performed
in patients at the end of the year by an Israeli
biotechnology company that works with
professors to develop innovative technology. As stated by survey’s participant Prof.
Avinoam Kantouri in Daily Telegraph "There is a great need for artificial bones for traumas
and surgeries;" "We used the three-dimensional technology to build bone
in the shape and the appropriate
geometry. We can now grow bone outside the
body and then transplant it into the patient at
the right time. Scanning the
damaged area, the graft will
fit perfectly in place
and then can be merged successfully with other tissues. Of course, there will be
no issue of rejection, as it comes from the same cells
of the patient".
Following this method, three-dimensional printers are
used to accurately calculate the dimensions of the broken bone and then create a
mold that has gel texture. Stem cells taken, also known as mesenchymal stem cells
have the ability to repair and regenerate tissues and were removed from patient’s
fat using the method of liposuction. Then stem cells are placed in an automatic
device, the bioreactor, which provides the right conditions to enable them to
grow into bone.
Such marrow transplants have already been successfully performed on animals.
