    Abstract: The present invention relates to a method for the production of a diterpene or a glycosylated diterpene, which method comprises: a. fermenting a recombinant microorganism of the genus Yarrowia in a suitable fermentation medium at a temperature of about 29° C. or higher, wherein the microorganism comprises one or more nucleotide sequence(s) encoding: a polypeptide having ent-copalyl pyrophosphate synthase activity; a polypeptide having ent-Kaurene synthase activity; a polypeptide having ent-Kaurene oxidase activity; and a polypeptide having kaurenoic acid 13-hydroxylase activity and whereby expression of the nucleotide sequence(s) confer(s) on the microorganism the ability to produce at least steviol; and b. recovering the diterpene or glycosylated diterpene.

    Abstract: A cardiogenin major isomer is obtained from a methanol extract of Geum japonicum and separated from its minor isomer. The separation of the two isomers can be achieved by chiral phase chromatography, e.g., using a Chiralpak® IC™ column. The purity of the isolated cardiogenin major isomer can be further increased by crystallization, yielding isolated cardiogenin major isomer having HPLC purity as high as 98.97% (a/a) at 210 nm and a potency of 95.50%) (w/w).

    Abstract: Synthetic triterpenoids and methods of using the same to induce gene expression and differentiation of stem or progenitor cells are provided. Furthermore, the present invention provides methods for producing a cell, such as a stem or progenitor cell, with induced gene expression by contacting a stem or progenitor cell with an effective amount of a synthetic triterpenoid to induce the expression of one or more of SOX9 (Sex determining region Y-box 9), COL2A1 (Type II Collagen (alpha1)), TGF-βI, TGF-p2, TGF-33, BMP2, BMP4, BMPRII (Bone Morphogenic Protein Receptor II), SMAD (Small Mothers Against Decapentaplegic) 3, SMAD4, SMAD6, SMAD7, TIMP (Tissue Inhibitor of Metalloproteinase)-1 or TIMP-2 in the stem or progenitor cell, wherein the stem or progenitor cell is not a mesenchymal stem cell, periosteium cell or osteoprogenitor cell. In one embodiment, the stem or progenitor cell is multipotent.
