Researchers have developed a hydrogel composed of poly(N-acryloylglycinamide) (PNAGAm) grafted with arginine (R)–glycine (G)–aspartic acid (D)–serine (S) peptide whose elastic modulus can be changed ...

It is relatively easy to grow cells in the lab but turning them into realistic models of human tissue is harder. This requires creating an environment that closely mirrors the conditions in the body’s ...

Block copolymer hydrogels as multifunctional effective cryoprotecting agents for red blood cells Freezing of medical tissue and cells usually requires the addition of cryopreservatives, although the ...

Organ failure impacts millions of patients each year and costs hundreds of billions of US Dollars. Over the last 30 years, scientists have utilized a combination of tools, methods, and molecules of ...

Hydrogels are often used as scaffolds in tissue engineering. Living cells infused into the material can, theoretically, grow through the gel until an entire piece of tissue forms. But to grow well, ...

In tissue engineering, the scaffold material must eventually degrade leaving behind only regenerated tissue. For hydrogels that serve as cell encapsulation platforms, hydrogel degradation must closely ...

Every day in the United States, 17 people die waiting for an organ transplant, and every nine minutes, another person is added to the transplant waiting list, according to the Health Resources and ...

Zustiak’s primary research interests are in hydrogel biomaterials and tissue engineering, with emphasis on developing novel biomaterials as cell scaffolds and drug screening platforms, and elucidating ...

(Nanowerk News) One of the primary goals in the field of tissue engineering and regenerative medicine is the development of artificial scaffolds that can serve as substitutes for damaged tissue. These ...
