Recent edit to Cluster of differentiation
Hello, and thank you for your recent contribution. I appreciate the effort you made for our project, but unfortunately I had to undo your edit because I believe the reference that you gave is irrelevent at the point.Feel free to contact me directly if you have any questions. Thank you! Ueutyi (talk) 07:47, 27 June 2016 (UTC)
