If the fibrocartilage tissue in the spine degenerates over time, an intervertebral disc – the “shock absorber” between the vertebrae of the spine – can “slip,” pinching the medulla or nerves. The consequences include intense pain or even paralysis.

Engineers at the University of California San Diego have developed biomimetic bone tissues that could one day provide new bone marrow for patients needing transplants.
Human lungs, like all organs, begin their existence as clumps of undifferentiated stem cells. But in a matter of months, the cells get organized. They gather together, branch and bud, some forming airways and others alveoli, the delicate sacs where our bodies exchange oxygen for carbon dioxide.
Many specialized cells such as those in the skin, gut or blood have a lifespan of only a few days. Therefore, steady replenishment of these cells is indispensable. They arise from so-called "adult" stem cells that divide continuously.
Researchers at Indiana University School of Medicine have successfully developed a method to grow inner ear tissue from human stem cells — a finding that could lead to new platforms to model disease and new therapies for the treatment of hearing and balance disorders.
A team of researchers at the University of Gothenburg’s Sahlgrenska Academy has managed to generate cartilage tissue by printing stem cells using a 3D bioprinter. The fact that the stem cells survived being printed in this manner is a success in itself.
A gene previously identified as critical for tumor growth in many human cancers also maintains intestinal stem cells and encourages the growth of cells that support them, according to results of a study led by Johns Hopkins researchers.
Scientists and collaborators have shed light on a longstanding question about what leads to variation in stem cells by comparing induced pluripotent stem cells (iPSCs) derived from identical twins.
Regenerative medicine using human pluripotent stem cells to grow transplantable tissue outside the body carries the promise to treat a range of intractable disorders, such as diabetes and Parkinson’s disease.
