1. A method of screening a pluripotent or multipotent cell for differentiation into a (i) heptogenic, (ii) myogenic, (iii) osteogenic, or (iv) endothelial specific cell line, comprising:

  • (a) providing a cell for which differentiation is to be determined, then (b) subjecting said cell to differentiating conditions; and

    then (c) detecting in said cell differential expression of;

    (i) at least one hepatogenic specific gene selected from the group consisting of stearlyl-CoA desaturase (SCD), 3-hydroxy-3-methylglutaryl-Coenzyme A reductase (HMGCR), insulin inducd gene 1 (INSIG1), chromosome 20 open reading frame 97 (C20orf97), lipase A (LIPA), fatty acid desaturase 1 (FADS1), 7-dehydrocholesterol reductase (DHCR7), apolipoprotein D (APOD), squalene epoxidase (SQLE), cholesterol 25-hydroxylase (CH25H), lipin 1 (LPIN1), insulin induced gene 1 (INSIG1), flavin cntaining monooxygenase 1 (FMO1), aldo-keto reductase family 1 member 1C (AKR1C1), insulin-like growth factor 2 receptor (IGFR2R), ATP-binding cassette sub-family A member 1 (ABCA1), X-box binding protein 1 (XBP1) and mucin 1 (MUC1);

    (ii) at least one myogenic specific gene selected from the group consisting of insulin-like grwth factor binding protein 3 (IGFBP3), caldesmonin 1 (CALD1), a disintegrin and metallproteinase domain 12 (ADAM12), transglutaminase 2 (TGM2), tumor necrosis factor receptor superfamily member 11b (TNFRSF11B), protein kinase H11 (H11), cardiac muscle alpha actin (ACTC), and sarcoglycan delta (SGCD);

    at least one osteogenic specific gene selected from the group consisting of;

    intracellular adhesion molecule 1 (ICAM1), osteomodulin (OMD), tissue inhibitor of metalloporteinase 4 (TIMP4), sex determining region Y box 4 (SOX4), secreted phosphoprotein 1 (SPP1), v-fos FBJ murine osteosarcoma viral oncogene homolog (FOS), alpha V integrin (ITGAV), prolactin (PRL), alpha 4 integrin (ITGA4), peroxisome proliferative activated receptor gamma (PPARG), secreted protein acidic cystein-rich (SPARC) sarcoma amplified sequence (SAS), and bone morphogenetic protein 1 (BMP1), (iii) at least one osteogenic specific gene selected from the group consisting of;

    intracellular adhesion molecule 1 (ICAM1), osteomodulin (OMD), tissue inhibitor of metalloproteinase 4 (TIMP4), sex determining region Y box 4 (SOX4), crystalin alpha B (CRYAB), secreted phosphoprotein 1 (SPP1), v-fos FBJ murine steosarcoma viral oncogene homolog (FOS), alpha V integrin (ITGAV), prolactin (PRL), alpha 4 integrin (ITGA4), peroxisome proliferative activated receptor gamma (PPARG), secreted protein, acidic, cystein-rich (SPARC), sarcoma amplified sequence (SAS), and bone morphogenetic protein 1 (BMP1), or (iv) at least one endothelial specific gene selected from the group consisting of pentaxin-related gene rapidly induced by IL-1 beta (PTX3), selenprotein P plasma 1 (SEPP1), tissue factor pathway inhibitor (TFP1), angiopietin 1 (ANGPT1), angiopoietin-like 2 (ANGPTL2), 3-hydroxy-3-methylglutaryl-Coenzyme A reductase (HMGCR), kruppel-like factor 4 (KLF4), endothelial differentiation lysophosphatidic acid G-protein coupled receptor 2 (EDG2), matrix metalloporiteinase 14 (MPP14), neronal cell adhesion molecule (NRCAM), interleukin 6 (IL6), and tumor necrosis factor, alpha-induced protein 6 (TNFAIP6);

    wherein (i) upregulation of expression of said at least one hepatogenic specific gene indicates differentiation of said cell into a heptogenic specific cell line, (ii) upregulation of expression of said at least one myogenic specific gene indicates differentiation of said cell into a myogenic specific cell line, (iii) upregulation of expression of said at least one osteogenic specific gene indicates differentiation of said cell into an osteogenic specific cell line, or (iv) upregulation of said expression of said at least one endothelial specific gene indicates differentiation of said cell into and endothelial specific cell line.
