General description

RGD sequences on extracellular matrix proteins (fibronectin, vitronectin) promote cell adhesion to cellular integrin receptors. The thiol group on the N-terminus of TrueGel3D® RGD peptide acts as linker to bind RGD motif to the polymer (Dextran/PVA). The conjugated RGD motif on polymer promotes adhesion of cells with appropriate integrin receptors.
TrueGel3D® is a commercially available polymer-based diverse array of scaffolds for 3D in vitro tumor models. The RGD peptide present in these hydrogels enable cell attachment.

There is growing appreciation of the role that the extracellular environment plays in regulating cell behavior. Mechanical, structural, and compositional cues, either alone or in concert, can drastically alter cell function. Biomaterials, and particularly hydrogels, have been developed and implemented


TrueGel3D™ synthetic hydrogel can be used to study co-culture of tumor and stromal cells.

Fibroblasts that are present in the stroma secrete glycoproteins and polysaccharides to form extracellular matrix. They maintain the structural integrity within the connective tissue and play a key role in cancer, chronic obstructive pulmonary diseases, idiopathic pulmonary fibrosis, scleroderma and several other diseases.

The TrueGel3D™ hydrogel is formed by crosslinking RGD (arginylglycylaspartic acid) degradable polymer with CD cell-degradable crosslinker. Troubleshoot hydrogel formation and cell viability with this article.
