Subconfluent fibroblast cultures from Atrflox/- mice or wildtype B6 mice were transduced with MSCV-IRES-GFP or MSCV-Cre-IRES-GFP. Cells were cultured for 4 days, splitting as necessary, and replated for 1 day before treatment with 4 M aphidicolin. Before treatment and 16 hours after addition of aphidicolin cells were labeled with 10 M BrdU for 75 minutes and examined for BrdU incorporation and DNA content as described (Tough, D. F. & Sprent, J J. Exp. Med.179, 1127–1135 (1994)). Raulet et al (MS 2004-12-27903B-Z)
