Development of Synthetic Peptide Growth Factors by PeptiGrowth

Conventional growth factors and cytokines used in the manufacturing of regenerative medicine and cell therapy products are facing various challenges such as lot-to-lot quality variation, potential contamination with biological impurities, low stability, and high cost. PeptiGrowth has been working on the development of a series of synthetic peptides that have the same functions as conventional growth factors and cytokines, and that can address and solve all these challenges. Its peptides are completely chemically synthesized and animal component-free.

About TGFβ1 inhibitor (TGFβ1 binding peptide) (Product code: PG-002)

  • Inhibitory activity against TGFβ1 (ligand)

Existing small molecule inhibitors must enter the cell to inhibit TGFβ1 activity. On the other hand, PG-002 is a peptide that binds to and exhibits inhibitory activity against TGFβ1 (ligand), which acts outside cells. The inhibitory activity against TGFβ1 was measured by SBE Reporter Assay, and PG-002 showed 100% inhibitory activity at 10nM against 0.13nM TGFβ1 (Figure A). Using the panel assay, we also confirmed that it does not inhibit other signaling pathways. We recommend using PG-002 when the neutralization of TGFβ1 is required in cell culture.

About HGF Alternative Peptide (c-Met Agonist) (Product code: PG-001)

Prior to TGFβ1 inhibitor, PeptiGrowth has launched a synthetic peptide growth factor, PG-001, which has the same functions as native Hepatocyte Growth Factor (HGF). PeptiGrowth demonstrated that PG-001 activates c-Met (HGF-target receptor) by phosphorylation and supports cell (HUVEC) proliferation as shown in Figure B and C above respectively.
