Doctors may soon be able to ‘draw’ new bone, skin and muscle on to patients, after scientists created a pen-like device that can apply human cells directly on to seriously injured people.
The device contains stem cells and growth factors and will give surgeons greater control over where the materials are deposited.
It will also reduce the time the patient is in surgery by delivering live cells and growth factors directly to the site of injury, accelerating the regeneration of functional bone and cartilage, scientists said.
Doctors and scientists in Southampton have completed their first hip surgery with a 3D printed implant and bone stem cell graft.
The 3D printed hip, made from titanium, was designed using the patient’s CT scan and CAD CAM (computer aided design and computer aided manufacturing) technology, meaning it was designed to the patient’s exact specifications and measurements.
The implant will provide a new socket for the ball of the femur bone to enter. Behind the implant and between the pelvis, doctors have inserted a graft containing bone stem cells.
The graft acts as a filler for the loss of bone. The patient’s
A recent report published in the medical journal Stem Cell Reports, sheds light on breakthrough research regarding the use of thyroid cells derived from stem cells for new therapies. Scientists at Boston University’s School Medicine led the work.
They have pinpointed a means of efficiently engineering thyroid cells by way of stem cells that will eventually help analyze and treat thyroid diseases (…)
The breakthrough described above was discovered after studies were performed on mice. Stem cells are valued as they can mature into an array of different cell types.
