From: Transfer of malignant trait to immortalized human cells following exposure to human cancer serum
Cancer patient serum sustained the proliferation and colony-forming capability of hESCs but did not turn them into cancerous cells. (A) hESCs were cultured for 10 days in control human serum (CTL) or cancer patient sera (see Additional file 1: Table S1), then transferred to stem cell culture medium for 14 additional days. (B) The percentage of colonospheres formed under each condition. (C) Proliferation of hESCs cultured as monolayer in either culture media.
