MENLO PARK, Calif.--(BUSINESS WIRE)--Feb. 7, 2006--Geron Corporation (Nasdaq:GERN) announced today the launch of a new immortalized human cell line available through ATCC(R) (American Type Culture Collection). The new line, T HESC, is a human endometrium fibroblast-like cell line immortalized with human telomerase reverse transcriptase (hTERT).

The endometrial cells used to produce the T HESC line were obtained from an endometrial myoma.
