Therapeutically superior mesenchymal stem cells derived from the cranial bone offer hope in reversing paralysis and language impairment in moderate to severe cases of stroke.

Old muscle stem cells express high levels of the cancer-associated molecule CD47. Blocking a pathway mediated by CD47 restored strength to old mice in a Stanford Medicine study.

Cedars-Sinai Investigators Confirm Safety of a Novel Therapy Targeting Motor Neurons That Die in Patients With ALS

Replacing sick or damaged cells with healthy cells: this is a major goal of regenerative medicine. One of the most promising approaches is cellular reprogramming, whereby one cell type in our body converts to another cell type. Research carried out at Helmholtz Munich and Ludwig-Maximilians-Universität München has discovered new ways to improve the cellular reprogramming efficiency, unlocking potential for cellular repair therapies.

New findings highlight transfusions of bone-marrow stem cells as a potential treatment approach for sepsis patients.

A Johns Hopkins Medicine scientist who spent 30 years figuring out how to put chemical labels into cells to track their movement in living tissues has found that certain self-renewing stem cells have built-in tracers — made out of sugars — that can do the job without added chemical “labels” when injected into mouse brains. The finding, made with stem cells widely engineered into experimental therapies for multiple sclerosis and other neurodegenerative diseases, was a welcome surprise, the investigators say.

What happens in our respiratory tract once COVID-19 invades? A three-dimensional airway model, made from patient-derived stem cells, could provide answers about the initial stages of infection. The model not only replicates the infection process, but can be used to test potential antiviral drugs.

Removing one type of T cell from donor blood used for stem cell grafts could greatly reduce a serious complication called graft-versus-host disease in patients with leukemia, according to a new study.
