Col1a1^{tm3(tetO-Pou5f1,-Sox2,-Klf4,-Myc)Jae}

RMCE on KH2 cells inserted a cassette that contains a loxP-flanked pgkNEOpolyA cassette, the tetracycline responsive element (TRE or tetO), the single polycistronic expression cassette 4F2A, and SV40 intron plus polyA signal into the 3'UTR. The 4F2A cassette contains the four mouse reprogramming genes Oct4 (Pou5f1; POU domain, class 5, transcription factor 1), Sox2 (SRY-box containing gene 2), Klf4 (Kruppel-like factor 4 (gut)), and c-Myc (Myc; myelocytomatosis oncogene) separated by three different viral 2A oligopeptides that mediate ribosomal skipping (P2A [from porcine teschovirus-1], T2A [from insect Thosea asigna virus], and E2A [equine rhinitis A virus], respectively).
