Bioactivity of released TGFβ2 from electrospun scaffolds on cells growing in monolayers. Scaffolds loaded with 13 ng and 100 ng of TGFβ2/mg of scaffold were submerged in the culture media without having direct contact with the cells. A permeable support was used to elevate the scaffolds above the cell level. Cell count was assessed after 5 days in culture. Error bars shown are standard deviation (*p < 0.05; n=5).
