Stem-cell treatment may have cured woman of HIV

An HIV-positive woman who received a blood stem cell transplant to treat acute myeloid leukemia appears to have been cured of HIV. The stem cells, from umbilical cord blood, contained a gene variant that makes them resistant to HIV infection. The woman has been free of HIV for 14 months since the treatment. This finding […]

‘Rejuvenating’ the Alzheimer’s brain

Alzheimer’s disease is the main cause of dementia and current therapeutic strategies cannot prevent, slow down or cure the pathology. The disease is characterized by memory loss, caused by the degeneration and death of neuronal cells in several regions of the brain, including the hippocampus. Researchers have identified a small molecule that can be used […]

Stem cell scientists make big progress in building mini-kidneys

Researchers have created what could be a key building block for assembling a synthetic kidney. They describe how they 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. The organoids provide a way to study kidney disease […]

How to boost muscle regeneration and rebuild tissue

One of the many effects of aging is loss of muscle mass, which contributes to disability in older people. To counter this loss, scientists at the Salk Institute are studying ways to accelerate the regeneration of muscle tissue, using a combination of molecular compounds that are commonly used in stem-cell research.

Identification of Liver Cancer Stem Cell Stemness Markers Using a Comparative Analysis of Public Data Sets

National Institutes of Health and other agencies are funding high-throughput genomics and transcriptomics (‘omics) experiments that deposit digital samples of data into the public domain at a rapidly increasing scale.1,2 The importance of these digital samples of data is further illustrated by the growing number of linked peer-reviewed publications that demonstrate its scientific value.3,4 Investigations of cancer […]
