1911 Jrnl. Exper. Med. 14 245 Fetal tissues of the chicken grew extensively in human, rabbit, and dog plasma. In general, however,..the development of the tissues is slighter..in heterogenic than in autogenic and homogenic plasma.

1920 Jrnl. Pathol. & Bacteriol. 23 366 There is established the existence of an apparently specific relationship between the lipoids of heterogenic organs and the heterogenetic antibody.

1922 Jrnl. Exper. Med. 35 17 It would be of advantage to cultivate chicken tissue in heterogenic serum because it is much more difficult to keep alive in vitro permanently a strain of mammal fibroblasts than of chicken fibroblasts.
