Remarks:

The WI-38 cell line was developed in July 1962 from lung tissue taken from a therapeutically aborted fetus of about 3 months gestational age. Cells released by trypsin digestion of the lung tissue were used for the primary culture. The cell morphology is fibroblast-like. The karyotype is 46,XX; normal diploid female. A maximum lifespan of 50 population doublings for this culture was obtained at the Repository. A thymidine labelling index of 86% was obtained after recovery. G6PD is isoenzyme type B. This culture of WI-38 is an expansion from passage 9 frozen cells obtained from the submitter.
