Human Bones Successfully Grown In The Lab

In a recent experiment, scientists at the Columbia University successfully grew human bones from stem cells in a lab. The team used digital images of an intact jaw bone to create a three-dimensional replica, called a scaffold. They then turned it into a living tissue by placing it in a similar-shaped chamber, adding human stem cells extracted from bone marrow. The chamber was fed with growth hormones, oxygen and nutrients to enable the bone to flourish.

In a similar research at the University of Michigan, scientists plan to recreate jaw bones within the human body itself by filling the scaffold with bone marrow cells from the patient and implanting it, to be absorbed by the body.

These experiments are significant as they could result in doing away with painful bone grafting or using titanium that is not entirely compatible with the host bones.
