Cloned into BamHI and NheI web sites. Expression vector and packaging vectors
Cloned into BamHI and NheI web sites. Expression vector and packaging vectors (8.9 and VSVg) were transfected into 293T cells working with Lipofectamine 2000 (Invitrogen), and medium was collected twice just about every 24 h. Viruses were centrifuged at 65,000 g ta 4 for two.5 h and suspended in HBSS. Mouse tracheal epithelial cells had been dissociated with 0.1 trypsin/EDTA and seeded on rat tail collagen I-coated, 24-well 0.4-m inserts at 7.5 104 cells per insert. Medium was changed every single other day. Lentivirus was added on top at day three. When cells reached confluence, the overlying medium was removed andE3648 | pnas.org/cgi/doi/10.1073/pnas.Tadokoro et al.Dr. Yen-Rei A. Yu for advice on FACs analysis, Danielle Hotten for assistance, and Dr. Ken Poss for vital comments on the manuscript.
