PhotoHA®-INK (Soft)
Methacrylated Hyaluronic Acid (GM-HA)
Catalog #D16110025376
PhotoHA®-INK (soft) is 5 mL of a 4% solution of methacrylated hyaluronic acid (GM-HA) in PBS with 0.5% LAP. PhotoHA® (soft) is a GM-HA which provides softer hydrogels than the (stiff) HAMA. This ink is pre-formulated and ready for cell printing in the BIONOVA X.
Product Description
Advanced BioMatrix offers PhotoHA®-INK, 5 mL of methacrylated hyaluronic acid (GM-HA) pre-formulated for photocrosslinkable hydrogels with the BIONOVA X DLP 3D Bioprinter. The product is a 4% solution with 0.5% LAP.
Hyaluronic acid is the most abundant glycosaminoglycan in the body being an important component of several tissues throughout the body. While it is abundant in extracellular matrices, hyaluronic acid also contributes to tissue hydrodynamics, movement and proliferation of cells, and participates in a number of cell surface receptor interactions.
For the majority of cell types, it is recommended to add additional ECM proteins to the hyaluronic acid hydrogels. The proteins provide important cell binding sites.
Product Q & A
Yes. There are quite a few publications citing various hyaluronidase protocols for digesting PhotoHA hydrogels. Here are a few:

The HA we use comes from biotechnological production, where the hyaluronic acid is extracted from the cell walls of the bacteria Streptococcus zooepidemicus.
The top represents PhotoHA-Stiff (HAMA). The bottom represents PhotoHA-Soft (GMHA).

Product Cell Assay
Human mesenchymal stem cells (20 x 106 / mL) were encapsulated in 50 μL hydrogels (~ 4.7 mm x 2 mm). Hydrogels (1 wt% PhotoHA®) were fabricated with 0.05 wt% Irgacure 2959 and exposure to 2 mW/cm2 light (320-390 nm) for 10 minutes. After 24 hours, encapsulated cells were stained with calcein AM and ethidium homodimer and subsequently imaged on a Leica SP5 confocal microscope (using FITC/TRITC sequential scans).

PhotoHA® Methacrylated Hyaluronic acid can be used to form hydrogels for ex-vivo engineering of autologous cartilage tissue[1] or as a mesenchymal stem cell carrier in cartilage repair[2].
Because the stiffness can be widely adjusted by altering concentration or UV-light exposure, methacrylated HA has been used to measure the effects of matrix stiffness on cell phenotype and function[3][4].
Methacrylated HA can be used for 3D bioprinting (extrusion[5], inkjet[5] and photolithographic[6]) to create structures that promote osteogenic differentiation of MSC’s[7].
The high tunability of hyaluronic acid methacrylate allows it to be mixed with, and reinforce other types of hydrogels (such as collagen, or gelatin methacrylate)[8].
