HeLa - Wikipedia

HeLa (/ ˈ h iː l ɑː /; also Hela or hela) is an immortal cell line used in scientific research. It is the oldest and most commonly used human cell line. The line is named after and derived from cervical cancer cells taken on February 8, 1951, from Henrietta Lacks, a 31-year-old African-American mother of five, who died of cancer on October 4, 1951. The cell line was found to be remarkably ... To get more information, visit the site
