Abstract:
To compare the growth factors mRNA expressions in human skin fibroblasts cultured in two (2D) or three dimensional systems (3D). Human skin fibroblasts were isolated and cultured in collagen jelly (3D) or the regular culture plates (2D). After 72 hours, the total RNA of fibroblasts were extracted. Specific oligonucleotide primers for the growth factor VEGF and bFGF were synthesized and reverse transcriptase polymerase chain reaction (RT PCR) was utilized to amplify the mRNA of those growth factors. RT PCR productions were separated by electrophoresis in 1% wt/vol agarose gels and photographed. Semi quantitative data were statistically analyzed. Although the morphology of fibroblasts in 3D culture was different from that in 2D culture, the RT PCR analysis revealed the same expression and concentration of VEGF mRNA and bFGF mRNA in human skin fibroblasts cultured in different systems.
