Pesquisadores na Suécia criaram células produtoras de insulina a partir de células-tronco humanas que reverteram os sintomas do diabetes após serem transplantadas em camundongos. As células amadureceram após serem colocadas no olho e mantiveram a regulação da glicose por meses. O trabalho foi publicado na Stem Cell Reports.

Cientistas do Karolinska Institutet desenvolveram um protocolo aprimorado para derivar ilhotas pancreáticas a partir de várias linhagens de células-tronco pluripotentes humanas. O método utiliza condições de cultura refinadas e aglomerados tridimensionais para reduzir tipos celulares indesejados e aumentar a resposta à glicose.

McGill researchers use reversible drug approach to boost natural killer cells against hard-to-treat cancers

Researchers at McGill University report a drug-based method to temporarily enhance natural killer (NK) cells—an immune cell type—by inhibiting two proteins, improving the cells’ ability to attack several aggressive cancers in preclinical experiments.

Rebooting stem cells builds bigger muscles in aged mice

Researchers have shown that rejuvenating muscle stem cells from old mice leads to larger muscle growth and improved recovery after injury. The approach could one day help older people regain strength and mobility. Experiments demonstrated clear benefits in leg function and tissue repair.

Virus injection halts pancreatic tumor growth in trial

A genetically engineered virus has stopped pancreatic tumors from growing in three patients in an early US clinical trial. The results come from a safety study led by researchers at the University of Minnesota.

Japanese scientists develop enhanced vitamin K for neuron regeneration

Researchers in Japan have created new vitamin K compounds that are three times more effective than natural forms at turning stem cells into neurons. The work, published in 2025, targets diseases that destroy brain cells such as Alzheimer’s and Parkinson’s.

Duke-led Nature study links glia-to-neuron mitochondria transfer to reduced nerve pain in neuropathy models

24 de maio de 2026 Reportado por IA Verificado

Duke University researchers report that boosting the transfer of healthy mitochondria from support cells to sensory neurons reduced pain-like behaviors in mouse models of diabetic and chemotherapy-related peripheral neuropathy, an approach they say could address a root driver of nerve pain rather than simply blocking pain signals.
