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.
A team of scientists at the Keck School of Medicine of USC has created what could be a key building block for assembling a synthetic kidney. In a new study in Nature Communications, Zhongwei Li and his colleagues describe how they can generate rudimentary kidney structures, known as organoids, that resemble the collecting duct system that helps maintain the body’s fluid and pH balance by concentrating and transporting urine.
