Color-changing fluorescent dyes allow for accurate temperature measurements within living cells
A novel single fluorophore ratiometric fluorotherm developed using solvent-dyed dyes achieved record sensitivity and enabled live cells and environmental sensing. Credit: Science Tokyo Temperature is an important variable that affects countless biological processes at the cellular level. However, accurate measurement of temperature within living cells remains difficult. Traditional temperature measurement techniques often lack the spatial resolution required to detect subtle…

How chlamydia forms protective bubbles to survive within human cells
Chlamydiatrachomatis inclusions (brown) in McCoy cell cultures. Credit: Public Domain Bacterium chlamydia trachomatis is the main cause of sexually transmitted diseases. Bacteria have many tricks on their sleeves that help them survive within the cell. One strategy used by chlamydia is to form a protective “bubbles” called inclusion. This is the fusion of membranes to create large pockets of large…

Nanoparticles supply microRNAs to muscle stem cells for potential muscular dystrophy treatment
Immunofluorescence staining of skeletal muscle from mice treated with microearn nanoparticles. Credit: Alvaro Somosa In international collaboration, researchers have made important breakthroughs in the therapeutic delivery of microRNAs against the previously untreated disease, Duchenne muscular dystrophy. Duchenne muscular dystrophy is a hereditary disorder characterized by progressive loss of muscle mass due to mutations in the dystrophin gene. Without the corresponding…

Specially delivered nanoparticles can program stem cells while in the body
After injecting 105 LNPs, we isolated the Lin- population from bone marrow, quantified LNPs (barcodes), functional delivery (aVHH proteins), and cell identity (transcriptome) in single cells, and analyzed the data. were superimposed. Credit: Nature Biotechnology (2024). DOI: 10.1038/s41587-024-02470-2 Intermediaries get a bad rap for adding cost and complexity to surgeries. Therefore, eliminating intermediaries reduces expenses, simplifies processes, and increases efficiency…

Brain cells mature faster in space, but stay healthy: ISS study
Credit: Stem Cell Translational Medicine (2024). DOI: 10.1093/stcltm/szae070 Microgravity is known to alter muscles, bones, the immune system, and cognition, but little is known about its specific effects on the brain. To understand how brain cells respond to microgravity, Scripps Research Institute scientists teamed up with the New York Stem Cell Foundation to send small clumps of stem cell-derived brain…
