New Emtree Release Includes Changes in Cell Line Terminology

11. June 2014

The May 12, 2014, release of Emtree contains an additional 720 preferred terms (including 87 drug terms) added since January 2014. This brings the total number of preferred terms in Emtree to 69,931. Information on the new terms is available at:

Many of the new medical terms added to this Emtree edition represent cell lines and tumor cell lines. The "cell line" and "tumor cell line" headings now appear only as Narrower Terms under "Anatomical Concepts", and no longer under "Procedures, Parameters and Devices".

Other highlights include:

  • Over 290,000 synonyms (more than 180,000 for drugs and chemicals)
  • Over 3,000 specific terms for general and medical devices (e.g., endoscopes, catheters, prostheses)

Customers running SDIs in Embase and/or Embase Alert should consult the new thesaurus to determine if the search terms in their strategies need to be updated.
