GelMA hydrogels can be gained readily by photopolymerization of GelMA prepolymer. Also, the hydrogel properties can be engineered during the preparation processes. Notably, GelMA hydrogels are similar to ECM, and this feature is the basis of further applications in biomedical field.
Gelatin methacryloyl (GelMA) is a modified form of gelatin that has been chemically functionalized with methacryloyl groups, allowing it to form a stable hydrogel when exposed to UV light and a photoinitiator. This methacrylic anhydride-modified gelatin is used as a base for 3D printing hydrogel bioinks, particularly for applications in tissue engineering, 3D bioprinting, and regenerative ...
GelMA, or gelatin methacrylate, is a photocrosslinkable hydrogel derived from collagen. It has biocompatible, biodegradable, tunable and bioprintable properties that enable various applications in tissue engineering and regenerative medicine.
GelMA hydrogels closely resemble some essential properties of native extracellular matrix (ECM) due to the presence of cell-attaching and matrix metalloproteinase responsive peptide motifs, which allow cells to proliferate and spread in GelMA-based scaffolds. GelMA is also versatile from a processing perspective.
Gelatin methacryloyl (GelMA) hydrogels have been extensively used for drug delivery and tissue engineering applications due to their good biocompatibility, biodegradability, and controllable photocurable efficiency. Phosphate buffer solution (PBS) is the most widely used reaction system for GelMA synthesis. However, carbonate-bicarbonate buffer solution (CBS) has been tried recently for ...
GelMA is a biocompatible and tunable polymer derived from gelatin, used for biomedical and tissue engineering. Learn how GelMA crosslinks, degrades, and interacts with cells, and how to characterize its mechanical and structural features.
GelMA Hydrogel Mechanisms in Wound Healing. GelMA, created by cross‐linking gelatin with methacrylic acid, used for 3D‐printed wound dressings, enhances healing through: (1) Keratinocyte proliferation, differentiation and epidermal layering; (2) Epithelial cell growth and adhesion; (3) Fibroblast recruitment and migration; (4) Transporting germicidal agents like AgNP; (5) Wound closure and ...

GelMA is a gelatin derivative containing a majority of meth-acrylamide groups and a minority of methacrylate groups, we suggest that "gelatin methacryloyl" is a more suitable name, which also matches the widely accepted abbreviation GelMA. GelMA undergoes photoinitiated radical polymerization (i.e.
Gelatin methacryloyl (GelMA) is a versatile material for a wide range of bioapplications. There is an intense interest in developing effective chemical strategies to prepare GelMA with a high ...
