  • Recombinant human FGFbasic-TS (HZ-1285) stimulates dose-dependent proliferation of the HDFa human primary fibroblast cell line. Cell number was quantitatively assessed by Promega CellTiter 96® cell viability reagent. HDFa cells were treated with increasing concentrations of recombinant FGFbasic-TS for 48 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 0.05-0.4 ng/mL.

  • Human induced pluripotent cells(iPSCs) were differentiated to definitive endoderm using HumanKine growth factors (Activin A- HZ-1138, bFGF-HZ-1285, BMP-4- HZ-1045, and Wnt3A-HZ-1296). The differentiation was confirmed by detection of expression of FOXA2(Red) and downregulation of pluripotency marker NANOG(yellow), in immunofluorescence

Background

Basic Fibroblast growth factor (FGFbasic), also known as bFGF, FGF2, FGF-β or HBGF-2, belongs to the FGF family. FGFbasic is involved in a number of biological processes including embryonic development and differentiation, neuron differentiation, survival, and regeneration, and the proliferation of cells of mesodermal origin and many cells of neuroectodermal, ectodermal, and endodermal origin (PMID 3272178, 3316527). FGFbasic is critical for human embryonic stem cells to remain in an undifferentiated state during cell culture (PMID 15782187).
