Abstract
We previously found that chicken egg white extract could promote cell survival and proliferation. In the present study, we further separated this extract into its components to identify those primarily responsible for promoting cell proliferation. Components of differing molecular weight were separated from chicken egg white extract by ultrafiltration and 293T cell cultures were supplemented with various concentrations. The effects on cell proliferation were subsequently determined by a CellTiter 96 Aqueous One Solution Cell Proliferation Assay kit (Promega). We demonstrate that components from chicken egg white smaller than 3 kDa in size are able to function as active ingredients promoting cellular proliferation. This discovery may identify a new and convenient additive for cell culture media to promote cell growth and proliferation.
