In order to compare what kinds of transcription factors are associated with the inhibition of preadipocyte cell proliferation, we prepared several grape extracts and tested the expression patterns by reverse transcription-polymerase chain reaction. As a result, 50% ethanol extract of Campbell early seed inhibited adipogenesis derived from the MDI solution. Extract of Campbell early seed was significantly inhibited lipid droplet formation and expression of molecular factors C/EBP-alpha and delta in 3T3-L1 cells. It is suggested that grape extracts of fractions would be a good candidate for the development of regional skin fat modulator.
