The TNF-α mouse was developed by Xenogen Biosciences, now Taconic. The model was created by microinjecting the human TNF-α gene. Taconic received stock in April 1996 at the second backcross from the C57BL/6 x SJL founder line. The mice were maintained by backcrossing hemizygous TNF-α mice to C57BL/6NTac inbred mice.
