The present invention relates to a recombinant microorganism, preferably a recombinant yeast, capable of producing caffeic acid comprising a heterologous gene coding for an enzyme of the hydrolase family capable of breaking, preferably of hydrolyzing, the caffeoyl-shikimate bond to produce caffeic acid from caffeoyl-shikimate. Said microorganism, preferably said recombinant yeast, may also be capable of producing ferulic acid from the caffeic acid obtained. The present invention also relates to a method for producing caffeic acid and a method for producing caffeic acid and/or ferulic acid, using microorganisms, preferably yeasts, according to the invention. Finally, the invention also relates to the use of microorganisms, preferably yeasts, according to the invention to produce caffeic acid and/or ferulic acid.

The present invention relates to a biomarker for prediction of proliferation and migration capacity of mesencymal stem cells and a use thereof, and more specifically, the present invention relates to a biomarker for prediction of proliferation or migration capacity of mesenchymal stem cells including peroxiredoxin 6 and a use thereof.

According to the present invention, by measuring the expression level of the biomarker, the proliferation and migration capacity of mesenchymal stem cells can be predicted.
