metastasis #2

　がん細胞が移転していく様子を映像で捉えることに成功しました。東京大学と理化学研究所の共同チームが成し遂げた業績です。
　記事の中で気になった単語は"metastasis"です。『Wisdom英和辞典第三版』(三省堂)を調べると「(癌(がん)細胞等の) 移転」という意味がありました。正常な細胞を緑色に着色し，がん細胞を赤色で示すことでがん細胞が移転していく様子を確認したようです。(Ume)

Spreading cancer caught on film

The way in which every single cancer cell spreads around the body has been captured in videos by a team in Japan.
The normal body tissues show up as green, while the cancer comes out as intense red spots.
The team, at the University of Tokyo and the RIKEN Quantitative Biology Center, says the technology will help explain the deadly process.
The research is on mice so far, but it is hoped the method could one day help with treatment too.
The spread of cancer around the body is a crucial moment called metastasis.
Before a cancer spreads it is easier to contain and cure, afterwards it is incredibly difficult.
The tumour itself has to evolve so bits of it are able to break free, survive travelling in the blood stream and invade new tissues.
