The embodiments herein disclose a method for synthesizing antagonistic peptide VEGF and bFGF. The method comprises synthesizing the antagonistic peptide for VEGF and bFGF and analyzing the purity of peptides. The quality of antagonistic peptide for VEGF and bFGF is analyzed by HPLC chromatogram and Mass spectrometry analysis. The biochemical activity of the antagonistic peptide for VEGF and bFGF is analyzed by competitive binding assay, cell proliferation assay, Matrigel assay for anti-angiogenic activity analysis, histopathological staining and Western blot analysis. The competitive binding assay of antagonistic peptide for VEGF and bFGF illustrate that peptides binds with cell receptors at a concentration of 2000 ng/ml. The cell proliferation assay illustrates that cell growth is arrested when antagonistic peptide for VEGF and bFGF are at a concentration of 2000 ng/ml. The anti-angiogenic activity analysis illustrates that angiogenesis is arrested when the concentration of antagonistic peptide for VEGF and bFGF is 2000 ng/ml.

The present disclosure provides composition, systems, devices and methods for plant-based production of non-plant proteins through the use of heterologous genes for the expression of said non-plant proteins. Non-plant proteins can include, but are not limited to, mammalian proteins, cytokines, or growth factors.

The invention features methods and compositions for treating a reperfusion injury, hypofusion, ischemic injury, and/or low/no-reflow. In embodiments, the compositions contain complexes containing a basic fibroblast growth factor (FGF2) and an immunoglobulin G (IgG) polypeptide, or fragments thereof. In embodiments, the complexes further contain a hepatocyte growth factor (HGF) polypeptide, a vascular endothelial growth factor (VEGF) polypeptide, or fragments thereof.

The present invention provides dominant negative mutants of FGF2 for suppressing FGF-mediated cellular signaling. Related compositions, methods, and kits are disclosed.

The present invention relates to a culture solution of MSCs derived from a fetus in amniotic fluid, and more specifically, to a composition for promoting hair growth or preventing hair loss, which includes a culture solution of MSCs overexpressing a reprogramming factor Nanog and derived from a fetus in amniotic fluid as an active ingredient. In addition, the present invention relates to a method for preparing the composition, which includes culturing Nanog-introduced MSCs derived from a fetus in amniotic fluid in a conditioned medium and collecting the culture solution. The conditioned medium composition according to the present invention exhibits a hair growth promoting effect, and thus is able to be used as cosmetic and pharmaceutical compositions for promoting hair growth.

Provided herein is a technology whereby a heterologous protein can be expressed in a bacterium which does not have an endogenous Tat system secretion machine.
