Additional file 3 of Uptake of different-sized microplastic particles in skin and corneal epithelial cells from Atlantic salmon
AI summary Read the abstract
This supplementary video shows tiny plastic particles (about the width of a human hair) being carried along inside salmon skin cells as they move, suggesting the cells actively transport the particles rather than just trapping them passively. While this study focuses on fish, it helps scientists understand how microplastics might get absorbed through skin and other tissues in animals—research that could eventually inform how these particles interact with human cells too.
Additional file 3. Supplementary video 2: Close-up of cells in a sheath transporting 12 µm polystyrene particles. Four large particles can be identified in the lower right at the start of the video by their dark outlines and bright centers. They are carried along as the mass of cells moves upward and toward the left. The particles seem to follow along with the same individual cells, although this is more readily apparent for the two lowest particles as their carrier cells become temporarily isolated from the larger cell mass.

Additional file 3 of Uptake of different-sized microplastic particles in skin and corneal epithelial cells from Atlantic salmon
AI summary Read the abstract
Note: this file is actually a supplementary video clip, not a full study — it shows tiny plastic beads (about the width of a fine human hair) being carried along by moving skin cells from salmon in a lab dish. It offers a small visual clue that microplastics can get pulled inside cells rather than just sitting on the surface, but on its own it doesn't tell us how this affects fish or human health — that would require the full study for context.
Uptake of different-sized microplastic particles in skin and corneal epithelial cells from Atlantic salmon
AI summary Read the abstract
Scientists found that skin and eye cells from salmon can absorb surprisingly large microplastic particles—up to 15 micrometers wide (about the size of some human cells)—and when cells team up in sheets, they can handle even bigger pieces. Surprisingly, most cells survived this exposure with their outer membranes intact, though larger particles did cause some distortion to the cells' internal structures. Since salmon are a major food source and share similar cell types with humans, this research helps scientists understand how microplastics might interact with living tissue, which is an important step in figuring out potential risks for both marine animals and the people who eat them.
Additional file 1 of Uptake of different-sized microplastic particles in skin and corneal epithelial cells from Atlantic salmon
AI summary Read the abstract
I don't have access to the actual content of this paper—only its title and a note that the abstract is a supplementary file with no substantive text provided. Based on the title alone, this appears to be a lab study looking at whether skin and eye (corneal) cells from Atlantic salmon absorb tiny plastic particles of different sizes, likely to understand how microplastics might affect fish health. **A note on relevance to humans:** Without the full findings, I can't say whether or how this connects to human health—fish cell studies don't automatically translate to people. If you can share the actual abstract or key results, I can give you an accurate, specific summary of what the

I don't have access to the actual content of this paper — only the title and a placeholder abstract ("Additional file 1"), which appears to be a supplementary data file rather than the full study. Could you provide the main paper's abstract or key findings? That way I can give you an accurate, plain-language summary rather than guessing at what the researchers actually discovered. That said, based on the title alone, here's what I can infer with appropriate caution: this research looked at how tiny plastic particles of different sizes get absorbed into skin and eye cells from Atlantic salmon. If microplastics can enter fish tissues through the skin and eyes, it
3D imaging shows nano- and microparticles are internalized by salmon skin and corneal epithelial cells
AI summary Read the abstract
Researchers used advanced 3D imaging to show that nano- and microplastic particles can be taken up by salmon skin and eye cells. The skin cells, which serve as the fish's first line of immune defense, actively internalized the plastic particles. The findings suggest that fish may absorb microplastics directly through their skin, not just through ingestion, opening up a previously underappreciated route of exposure.
