First-of-its-kind cell therapy promotes wound healing, improves overall wound health and lowers risks of recurrence. A team of researchers has engineered an innovative magnetic wound-healing gel that promises to heal diabetic wounds three times faster, reduce the rates of recurrence, and in turn, lower the incidents of limb amputations...

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest cancers worldwide, with a 5-year survival rate of less than 10%. Many PDAC tumors in early stage go undetected because they are not found using conventional imaging methods, including fluorodeoxyglucose positron emission tomography (PET) scans...

A UCLA-led team has identified an essential internal control mechanism that can promote the maturation of human stem cell-derived heart muscle cells, offering a deeper understanding of how heart muscle cells develop from their immature fetal stage to their mature adult form.

The findings, published in the journal Circulation, could lead to new therapies for heart disease and cardiac damage.

The collaborative effort with Duke-NUS Medical School in Singapore and other institutions identified an RNA splicing regulator named RBFox1, which was considerably more prevalent in adult heart cells than in newborns, based on a preclinical model. The sharp rise in RBFox1 during the maturation of heart cells was also confirmed through analyses of existing single-cell data.

“This is the fir...

New research helps explain why young children have lower rates of severe COVID-19 than adults. A study of infants and young children found those who acquired SARS-CoV-2 had a strong, sustained antibody response to the virus and high levels of inflammatory proteins in the nose but not in the blood. This immune response contrasts with that typically seen in adults with SARS-CoV-2 infection. The research was published in the journal Cell.

The investigation involved 81 full-term infants and young children whose mothers enrolled in a NIAID-supported cohort study at Cincinnati Children’s during their third trimester of pregnancy. The study team trained mothers to collect weekly nasal swabs from their infants starting when the babies were 2 weeks old...
