Discovery finds a cellular building block acts as a gel, not liquid as previously believed
Credit: CC0 Public Domain University of Alberta researchers have found an answer to a fundamental question in genomic biology that has eluded scientists since the discovery of DNA: Within the nucleus of our cells, is the complex package of DNA and proteins called chromatin a solid or a liquid? In a study published in the […]
New plant-based gel to fast-track ‘mini-organs’ growth, improve cancer treatment — ScienceDaily
– Monash University researchers have created the world’s first bioactive plant-based nanocellulose hydrogel to support organoid growth for biomedical applications. This includes cancer development and treatment. Nanocellulose gels cost a fraction of the price compared to the current gold standard. These hydrogels are plant-based and animal-free, and can mimic the human body conditions on a […]
Gel instrumental in 3D bioprinting biological tissues

Now, using a yield stress gel, Penn State engineers can place tiny aggregates of […]
