Innovations enhance genetic analysis of individual cells

"During the past decade, single cell genomics has evolved from science fiction to a trusted tool for biological research into subjects as diverse as the ecology of the ocean, the evolution of life, and the health of humans," said Ramunas Stepanauskas, director of the center and a senior research scientist at Bigelow Laboratory.

The enhanced techniques have already benefited numerous studies conducted with Bigelow Laboratory's assistance, ranging from the Gulf of Maine to the human body to world's deepest mines and the NASA spacecraft destined for Mars in 2020. They have also led to the development of several more advanced and cost-effective services that the center announced this month, making the technology widely accessible to research and industrial communities.

Traditional genetic analysis requires scientists to keep microorganisms alive in the laboratory, so that they can be grown to a large enough quantity -- billions of cells -- for DNA studies. As most microscopic organisms require conditions that are difficult to replicate in a lab, traditional methods are of limited use for examining most of life and genetic diversity on Earth.

"Single cell genomics has shown us that the microscopic world is larger and more complex than most ever believed possible," Stepanauskas said. "As this technology has been revolutionizing scientific studies, we have also been rapidly evolving our approaches to enhance their effectiveness and affordability."

The recent publication details several enhancements that Bigelow Laboratory's team has made to the technology and their impact on the study of microbes found in the environment. The enhancements include increasing the fraction of a genome that is recovered, coupling a cell's genome with valuable information about its size and other physical properties, as well as a major improvement in the technology's scalability.

"These developments and the new services they enable continue to grow the power and utility of this technology to aid researchers in their quest to understand the microbes that drive the planet and its health," Stepanauskas said. "We are also increasingly seeing biomedical researchers utilizing our technology, opening a new door to possible improvements in human health."
