We have previously developed a cell delivery and transfer technology for delivering autologous keratinocytes and melanocytes to patients with vitiligo. However, for this technology to benefit many patients geographically distant from the cell culture facility transportation issues need to be overcome. In this study we begin to investigate this by looking at what role surface chemistry and medium supplements, including fetal calf serum, CO2 gassing, and temperature, play in influencing cell viability. Cells were maintained on carriers for up to 48h outside of a CO2 incubator at 37°C and their subsequent ability to adhere and become organized into a new epithelium with appropriately located melanocytes was assessed. Consistently good viability and performance on an in vitro wound bed model was achieved by maintaining cells for 48h adherent to a 20% acrylic acid coated carrier at lower (around 23°C rather than 37°C) temperatures in the medium preperfused with CO2 before transport. Under these circumstances fetal calf serum was not required. In summary, the surface chemistry of the transport substrate and an appropriately CO2 buffered medium at near room temperature can extend the effective performance life of these cultured cells to at least 48h from when they leave standard incubator conditions. © 2011, Mary Ann Liebert, Inc.
