Researchers discover new method of cell separation

Seminar to examine role of media in politics

Isolation of trophoblast cells could be used in non-invasive prenatal diagnoses

University researchers have discovered how to separate cells containing fetal DNA from a mother’s cervical cells, a process that could eventually be used to help identify fetal disorders, according to Sumaiya Sayeed ’19.5 and Christina Bailey-Hytholt GS, researchers in the study. While this method has not yet been put into practice, the researchers hope to use it to diagnose disorders as early as five weeks into pregnancies while minimizing risk to mothers. The process enables the safe retrieval and isolation of trophoblast cells, which contain the DNA of the fetus, Bailey-Hytholt said. Similar to current methods of prenatal diagnosis that identify genetic abnormalities before birth, these trophoblast cells could eventually be used to identify disorders such as Down syndrome found in the DNA and chromosomes. “With our technique, you are getting the whole fetal genome,” Bailey-Hytholtsaid. “If you can isolate (the fetal genome), that really is getting the same material that you would be getting from these other tests.”

Previously, cervical swabbing would collect a mixture of cells including trophoblast cells. But the researchers found a way to separate the trophoblast cells from the other cervical cells based on their different densities, Bailey-Hytholt and Sayeed said. Using a microwell plate, they captured 90 percent of the heavier trophoblast cells, which stuck to the bottom of the

plate. After the researchers discovered how to separate the trophoblast cells, PerkinElmer, a biotechnology company that provided the samples for the study, isolated the cells. So far, the researchers have succeeded in using trophoblast cells to identify sex and now intend to continue with further testing. They also hope to collaborate with other companies

to expand their resources and applications, Bailey-Hytholt said. Unlike other methods for prenatal diagnosis in clinical use, this test does not require needles. Needles can lead to complications in the women undergoing the procedure, particularly those over the age of 30, Sayeed said.

As a staff writer for The Atlantic reporting on the 2020 Democratic presidential candidates, Isaac Dovere is no stranger to political journalism and its constant demands. But even as the campaign picks up this fall, Dovere will be taking the time to lead one of three non-credit study groups at the Watson Institute for International and Public Affairs this semester. The seminar — titled “Political Journalism in 2019” — will be closely related to Dovere’s professional work, focusing on the practice of journalism and how it can change views in the presidential campaign. “It’s really necessary to think about what we’re doing in journalism, think about what we’re doing in politics, (and) how those intersect with each other and how that is developing,” Dovere said.

R.I. reps call for gun safety action in Congress

UCS to hold elections for first-year reps

BY ISABEL INADOMI SENIOR STAFF WRITER Following the summer’s bout of mass shootings in cities such as Dayton, Ohio and El Paso, Texas, Rhode Island’s representatives in Washington are frustrated with the nation’s lack of action to reduce gun violence. Rep. David Cicilline ’83, D-R.I., who has repeatedly introduced legislation over the past several years that would increase national gun safety regulations, experienced a legislative win Tuesday when the House Judiciary Committee passed the Disarm Hate Act, which he had originally introduced, alongside two other bills relat-

ing to gun control. The act bans the sale of firearms to “anyone convicted of assaulting someone based on their race, religion, gender, sexual orientation, gender identity or disability,” wrote Francis Grubar, press secretary for Cicilline, in an email to The Herald. He added that these “misdemeanor hate crimes” are often precursors to more serious acts of violence. Cicilline’s fellow Rhode Island representative Rep. Jim Langevin, D-R.I., cosponsored the Disarm Hate Act and the other two bills that passed through the House Judiciary Committee Tuesday: the Extreme Risk Prevention Order Act, which allows law enforcement officers and family members to request a court order prohibiting an individual from purchasing or possessing firearms, and the Keep Americans Safe Act, which bans the import, sale, manufacture, transfer or
