A team of Canadian researchers has developed a new microarray platform they claim can image cells in vivo every 20 minutes for as long as a week. Led by scientists at Ï㽶ÊÓƵ in Montreal, the team designed the so-called "living microarrays" as a way to measure transcriptional changes in real time in single mammalian cells, and claims the approach could be used to study cell proliferation, differentiation, and apoptosis…

Sarav Rajan, who co-authored a paper on the new platform in BMC Genomics last week, helped to design it while he was a PhD student at McGill. Researchers from McGill, the Genome Quebec Innovation Centre in Montreal, and the Ontario Institute for Cancer Research in Toronto contributed to its development.
