Many people have experienced the struggles of dealing with low back pain. A common cause of this pain is degeneration of intervertebral disks (IVDs), which are located between the vertebrae and help give the spinal column its flexibility. Thus, IVD degeneration can lead to more serious conditions such as spinal deformity. In a recent article published in Biomaterials, a team led by researchers at Osaka University and Kyoto University demonstrated that using cartilage tissue derived from human stem cells could help prevent the loss of functionality from IVD degeneration.

It is believed that IVD degeneration originates in the nucleus pulposus (NP), which is composed of NP cells that produce the surrounding extracellular matrix (ECM)...

Stem cell study finds malfunctioning brain cells in patients who were diagnosed before age 50; researchers test potential new treatment. People who develop Parkinson’s disease before age 50 may have been born with disordered brain cells that went undetected for decades, according to new Cedars-Sinai research. The research points to a drug that potentially might help correct these disease processes.

Parkinson’s occurs when brain neurons that make dopamine, a substance that helps coordinate muscle movement, become impaired or die...

Houston Methodist researchers have identified an immune pathway that promotes the formation of a cell that can develop into new tissues and organs. In a new study published in the journal Stem Cells, a team led by John P. Cooke, M.D., Ph.D, described how activation of innate immunity enhances nuclear reprogramming, one of the first steps in tissue regeneration, or the formation of new tissues and organs from a single cell in the body.

“We found that activating the innate immune system opens up the DNA,” said Cooke, the study’s senior author...
