Abstract
In this study, we sought to establish a defined experimental system for fibroblast growth similar to that of the living dermis. To this end, we evaluated the growth and biochemical characteristics of fibroblasts cultured with serum-free HFDM-1, a finely tuned synthetic medium for human fibroblast culture. Three culture conditions were used to grow fibroblasts obtained from primary culture: (1) culture with Dulbecco’s modified Eagle medium (DMEM) plus 10 % fetal bovine serum (serum-supplemented DMEM), (2) culture with DMEM (serum-free DMEM), and (3) culture with HFDM-1 (HFDM-1), and fibroblast morphology, growth, collagen type I production, and lipid composition were analyzed. Fibroblasts grown in HFDM-1 maintained cell numbers at nearly 100 % from days 14 to 21 and produced more collagen type I than cells grown in serum-supplemented and serum-free DMEM. Arachidonic acid (20:4) and total polyunsaturated fatty acids were lower in cells grown in serum-free DMEM and HFDM-1 than in serum-supplemented DMEM. These results suggested that HFDM-1 recapitulated growth conditions in the dermis better than traditional, serum-supplemented DMEM. In addition, the controlled chemical composition of HFDM-1 eliminated a potential source of variability in cell culture conditions.
