Targeting Glycosaminoglycan-mediated Growth Factor Signaling to Influence Stem Cell Specification

Powering Stem Cell Fate with Glycosaminoglycan Innovation

The growth factor (GF) signaling pathway determines the fate of stem cells. It activates key signaling pathways involved in gene regulation. Among them, glycosaminoglycans (GAGs) are important mediators of growth factor signaling. At CD BioGlyco, we have constructed a professional Glycan Display Platform, and to explore the effects of targeting GAG-mediated GF signaling on stem cells by probing GAG-mediated cell signaling in stem cell development.

• Firstly, we provide reconfiguration of the glycocalyx. We manipulate the metabolic pathways responsible for glycan biosynthesis by covalently grafting GAGs to surface proteins or by passively inserting lipid-functionalized glycoconjugates into cell membranes. Here, we further explore their potentiation of nerve GF-mediated signaling.
• Secondly, we construct a microarray platform to identify GAG candidate genes with GF specificity.
  
  • We prepare a key polymer intermediate primed for disaccharide-GAG coupling and terminated with an azide group. In this process, we use quantitative fluorescent labeling to facilitate subsequent detection.
  • A library of proteoglycan structures is obtained by reacting polymer intermediates with GAG couplers. Nuclear magnetic resonance (NMR) hydrogen spectroscopy is used to analyze the degree of incorporation of individual glycans and their binding to GFs. The degree of remodeling of different proteoglycans is assessed by fluorescence microscopy.
• In addition, to change the effect of GAGs on GF activity, we offer modification of GAGs. We also provide a Western blot technique to analyze the effect of GAGs before and after modification.

Applications

• GAG-mediated modulation of GF signaling can be used to develop cell lineages and advance cell-based therapeutic research.
• Targeting GAG-mediated GF signaling to affect stem cells can be used in research on cell-to-cell communication, development, and disease progression. It also provides a powerful means of directing activity and triggering desired cellular responses.
