RE­SEARCHERS STUDY BRAIN CAN­CER CELLS US­ING DNA COD­ING

Montreal Gazette - - CANADA -

A Cana­dian-led re­search team is us­ing a “bar­cod­ing” sys­tem to in­ves­ti­gate the growth pat­terns of cells that make up the dead­li­est form of brain can­cer, glioblas­toma, with the hopes of im­prov­ing treat­ment. Re­search led by the Hospi­tal for Sick Chil­dren in Toronto and the U.K.’s Univer­sity of Cam­bridge is tag­ging ev­ery cell with a dif­fer­ent DNA bar­code. The re­searchers found only a small pro­por­tion of the bar­coded cells could give rise to long-term tu­mour growth, sug­gest­ing many tu­mours con­tain cells that can­not mul­ti­ply.
