Biology of the Cell was later retitled "Biologie Cellulaire" (; 1977–1980), becoming "Biology of the Cell" in 1981. Articles were originally published in either English or French, with summaries in both languages. Content from 1988 is available online in PDF format, with papers from 2005 also being available in HTML, and from 2006 in an enhanced full-text format. The journal's 2014 impact factor was 3.506. "Biology of the Cell" is indexed by BIOBASE, BIOSIS, CAB International, Cambridge Scientific Abstracts, Chemical Abstracts Service, Current Contents/Life Sciences, EMBASE/Excerpta Medica, MEDLINE/Index Medicus, and ProQuest Information and Learning Articles are primarily research and reviews.
