Application

Hyaluronic acid (HA) is a linear polysaccharide of alternating D-glucuronic acid and N-acetyl-D-glucosamine found primarily in connective tissues. HA based hydrogels are widely used in tissue engineering, 3D bioprinting, and drug deliery applications. The methacrylate functionalized hyaluronic acid is photo-crosslinkable, and can be used to generate crosslinked hydrogels.

Mesenchymal stem cells (MSCs) are multipotent progenitor cells whose plasticity and self-renewal capacity have generated significant interest for applications in tissue engineering. The objective of this study was to investigate MSC chondrogenesis in photo-cross-linked hyaluronic acid (HA) hydrogels. Because HA

Rational Design of ECMs Toward Cancer Immunotherapy

Engineered ECMs enhance immune therapy in cancer treatment by supporting cells and tissues and modulating immune response. They improve immune cell maturation, expansion, and regulation through biomaterial manipulation, acting as frameworks or carriers for enhanced tumor immunotherapy.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
