We show by fluorescence microscopy and flow cytometry that the addition of PLL to the viral-containing medium significantly increases the number of green fluorescence protein (GFP)-positive osteoblasts and BMSCs transduced with an enhanced GFP-expressing adenovirus. We also demonstrate that PLL can greatly enhance the adenoviral transduction of osteoblasts and osteocytes <jats:italic>in situ<\/jats:italic> in <jats:italic>ex vivo<\/jats:italic> tibia and calvaria, as well as in long bone fragments. In addition, we validate that PLL can improve routine adenoviral transduction studies by permitting the use of low multiplicities of infection to obtain the desired biologic effect. Ultimately, the use of PLL to facilitate adenoviral gene transfer in osteogenic cells can provide a cost-effective means of performing efficient gene transfer studies in the context of bone research.<\/jats:p>","DOI":"10.1038\/boneres.2016.21","type":"journal-article","created":{"date-parts":[[2016,8,9]],"date-time":"2016-08-09T09:40:27Z","timestamp":1470735627000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["A cost-effective method to enhance adenoviral transduction of primary murine osteoblasts and bone marrow stromal cells"],"prefix":"10.1038","volume":"4","author":[{"given":"Atum M","family":"Buo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark S","family":"Williams","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaclyn P","family":"Kerr","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph P","family":"Stains","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2016,8,9]]},"reference":[{"key":"BFboneres201621_CR1","doi-asserted-by":"publisher","first-page":"6479","DOI":"10.1074\/jbc.272.10.6479","volume":"272","author":"A Fasbender","year":"1997","unstructured":"Fasbender A, Zabner J, Chillon M et al.
