To achieve this goal, we took advantage of the easily accessed chick embryonic fibroblasts. Nine-day old chick embryonic fibroblasts were obtained and subjected to be transduced with a set of lentivirus to develop a chick induced pluripotent stem (ciPS) cell line. Morphological features, positive periodic acid-Schiff staining as well as strong immunocytofluorescence of alkaline phosphatase, intestinal (ALPI) and POU class 5 homeobox 1 (POU5F1) proteins suggested that these chick embryonic fibroblasts have been transformed into ciPS cells. Further differentiation and immunocytofluorescence assays confirmed that this ciPS cell line possesses capacities and potentials to form embryoid bodies, differentiate into all three embryonic layers: ectoderm, mesoderm and endoderm with evidence of strongly positive and specific molecular markers. Immunoblot analysis next demonstrated that through recombinant DNA technology and the 2<jats:sup>nd<\/jats:sup> generation lentiviral transfer system, the goose <jats:italic>hemagglutinin<\/jats:italic> gene (<jats:italic>H5<\/jats:italic>) gene was packaged into the replication-incompetent virus and highly expressed in a bladder cancer-derived cell line, T24, after transduction. The titer of ciPS-generated replication-incompetent virus is comparable to that from the Phoenix-AMPHO cell line, which is a commercial and high productive retrovirus producer. Our study successfully established a ciPS cell line which is able to produce replication-incompetent virus, providing a new strategy for cell-based vaccine production after virus inactivation.<\/jats:p>","DOI":"10.1038\/s41598-019-52282-7","type":"journal-article","created":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T11:08:43Z","timestamp":1572520123000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Establishment of an induced pluripotent cell line from Taiwan black silkie chick embryonic fibroblasts for replication-incompetent virus production"],"prefix":"10.1038","volume":"9","author":[{"given":"Jenn-Fa","family":"Liou","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen-Ren","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lih-Ren","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0798-5028","authenticated-orcid":false,"given":"Yow-Ling","family":"Shiue","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2019,10,31]]},"reference":[{"issue":"3","key":"52282_CR1","doi-asserted-by":"publisher","first-page":"18","DOI":"10.3390\/vaccines5030018","volume":"5","author":"Ilaria Manini","year":"2017","unstructured":"Manini, I. et al.
