A673

Tumourigenicity studies

Derived from a 15 year old female patient. The cells form colonies on soft agar and tumours in antithymocyte serum treated mice.

The cell line A673 was originally described in 1973 as derived from a rhabdomyosarcoma, however, more recent analysis of the cells using advanced diagnostic techniques determined the cells to have characteristics of Ewing sarcoma rather than rhabdomyosarcoma. See citations for more information about this tumour status.
