1908 - The term "stemcell" was proposed for scientific use by the Russian histologist Alexander Maksimov (1874–1928) at congress of hematologic society in Berlin. It postulated existence of haematopoietic stemcells.
1998 - James Thomson and coworkers derive the first human embryonic stemcell line at the University of Wisconsin–Madison.
