Patterning of PEG-based Hydrogels - Engineering Spatial Complexity

In this article, we will discuss the benefits and limitations of several 2D and 3D scaffold patterning techniques that can be applied in the presence of cells. Although these methods will be discussed in the context of poly(ethylene glycol) (PEG)-based hydrogels, they can technically be applied to any optically transparent, photoactive substrate.

Injectable Hydrogels for Cell Delivery and Tissue Regeneration

The use of hydrogel-based biomaterials for the delivery and recruitment of cells to promote tissue regeneration in the body is of growing interest. This article discussed the application of hydrogels in cell delivery and tissue regeneration.

Degradable Poly(ethylene glycol) Hydrogels for 2D and 3D Cell Culture

Progress in biotechnology fields such as tissue engineering and drug delivery is accompanied by an increasing demand for diverse functional biomaterials. One class of biomaterials that has been the subject of intense research interest is hydrogels, because they closely mimic the natural environment of cells, both chemically and physically and therefore can be used as support to grow cells. This article specifically discusses poly(ethylene glycol) (PEG) hydrogels, which are good for biological applications because they do not generally elicit an immune response. PEGs offer a readily available, easy to modify polymer for widespread use in hydrogel fabrication, including 2D and 3D scaffold for tissue culture. The degradable linkages also enable a variety of applications for release of therapeutic agents.
