Abstract

In the present study in vitro expansion of human keratinocytes by supplementing dermal fibroblasts conditioned medium (DFCM) has been reported. Effect of two different DFCM acquired by culturing fibroblasts in keratinocyte-specific medium (defined keratinocytes serum free medium, DFCM-DKSFM) and fibroblast-specific serum free medium (F12: DMEM nutrient mix, DFCM-FD) have been compared. Growth kinetics of keratinocytes in terms of efficiency of cell attachment, expansion index, apparent specific growth rate and growth potential at the end of culture was evaluated in culture supplemented with DFCM-DKSFM and DFCM-FD in comparison with control i.e. DKSFM only. Results indicated that supplementation of DFCM caused significant increase in keratinocyte attachment. Efficiency of keratinocyte attachment in culture supplemented with DFCM-DKSFM was significantly higher compared to those cultured in DFCM-FD and DKSFM. In addition, the expansion index of keratinocytes in cultures supplemented with DFCM-DKSFM and DFCM-FD were 3.7 and 2.2 times higher than that of control condition even though the apparent growth rate and proliferative potential was found significantly lower. These results suggested that supplementation of DFCM enhanced expansion of keratinocyte by increasing efficiency of cell attachment, and DFCM-DKSFM provided suitable condition for in vitro expansion of keratinocytes compared to DFCM-FD and control condition.
