Yale scientists repair injured spinal cords using patients’ own stem cells. Intravenous injection of bone marrow derived stem cells (MSCs) in patients with spinal cord injuries led to significant improvement in motor functions, researchers from Yale University and Japan report Feb.
Can stem cells repair spinal cord injuries?
Transplantation of stem cells or progenitors may support spinal cord repair. Stem cells are characterized by self-renewal and their ability to become any cell in an organism. Promising results have been obtained in experimental models of SCI.
What research is being done for spinal cord injuries?
Using spinal cord stimulation and physical therapy, Mayo Clinic researchers helped a paralyzed man stand and walk with assistance. The research proves networks of neurons below a spinal cord injury still can function after paralysis—and highlights the potential for developing effective treatments.
What injuries can stem cells repair?
Stem cell therapy can help heal ligament, tendon or muscle injuries such as in the rotator cuff or Achilles tendon. It also helps repair chronic, degenerative arthritis where cartilage in the joint is worn away.
How long does spinal cord injury take to heal?
Recovery, if it occurs, typically starts a week to six months after an injury. The fastest rate of recovery is often seen in the first six months, but some people experience small improvements for up to one to two years.
Can damaged spinal cord heal?
Damage to the spinal cord rarely heals because the injured nerve cells fail to regenerate. The regrowth of their long nerve fibers is hindered by scar tissue and molecular processes inside the nerves.
What are the negative effects of stem cell therapy?

Why stem cells are bad?
One of the bad things about stem cells is that they have been over-hyped by the media in regard to their readiness for treating multiple diseases. … Very commonly, mesenchymal stem cells are sold as treatments for multiple diseases, including SCI.
Why are people against stem cell research?
Some opponents of stem cell research argue that it offends human dignity or harms or destroys human life. … Laboratory research on adult stem cells is generally uncontroversial. Research with human subjects becomes controversial because some experimental “therapies” could harm patients.
What parts of the body can be paralyzed from a spinal injuries?
Also known as quadriplegia, this means that your arms, hands, trunk, legs and pelvic organs are all affected by your spinal cord injury. Paraplegia. This paralysis affects all or part of the trunk, legs and pelvic organs.
How long does it take for stem cell therapy to work?
Most patients feel no improvement for at least 3 weeks and possible 6-8 weeks. Once you feel improvement, you will notice continued improvement expanding over 6 months. What is the recovery like after a stem cell procedure?
What is the success rate of stem cell therapy?
Stem cell treatment has achieved positive results in over 45% of patients, according to one trial. Patients saw improvement in less than 6 months, which compares quite well with back surgery that usually involves very long recovery times.
