A new approach to growing heart muscle

An artificial cornea is in sight, thanks to biomimetic hydrogels

...ogram, was to design, fabricate and characterize a bioengineered cornea based on the dual-network hydrogel. The result was a disc with a clear center and tiny pores populating the periphery. Myung calls the pores engineered into his artificial cornea the "homes" he built for cells that need to infiltrate the artif...

UGA scientists engineer root-knot nematode resistance

...esn't come naturally in most crops, Hussey's group bioengineered their own. The results of the study were published Sept. 26 in the journal, Proceedings of the National Academy of Sciences. Four common root-knot nematode species account for 95 percent of all infestations in agricultural land. By discovering a ro...

UC Davis researchers move biotechnology closer to replacing electronic pacemakers

...positive and direct evidence in living models that bioengineered cells can replace the electronic pacemaker," said ...study, the researchers delivered a gene encoding a bioengineered cell-surface protein to heart muscle cells of pigs. This protein mimics the combined action of sever...

New cellular flaw found in some virulent breast cancers

...s reported in another Cancer Cell paper found that bioengineered mice in which cyclin D1 could not activate CDK4 kinase were developmentally normal and highly resistant to ErbB-2-caused breast cancers, demonstrating that blocking CDK4 was not harmful to the mice. That research was carried out by scientists at Tuft...
