Sound Waves Can be Used to Turn Stem Cells Into Bones Cells to Regrow BonesPeople who have lost bones to cancer or degenerative diseases might have hope to restore said bones soon. Researchers from RMIT have found a way to turn stem cells into bone cells through high-frequency sound waves (which are emitted by a low-cost microchip device developed by the university). This approach is more efficient and simpler compared to other methods, as it cuts the time required to turn stem cells into bone cells by several days. It also might be a less painful method compared to the others.Cheap and very simple to use, the researchers state that their device could be "vital for effective tissue engineering." Truly something to look forward to in the near future!(Image: RMIT)#StemCells #Soundwaves #TissueEngineering #Biotechnology

Scientists Create the World’s First 3D Printed Wagyu Beef Complete with Marbling Using Stem CellsWagyu meat is famous for its high intramuscular fat content, more commonly referred to as excellent “marbling” or sashi. This gives the meat its rich flavor and its distinctive texture. However, the process of raising cattle and producing these in-demand cuts of beef is deemed unsustainable due to the disproportionate amount of climate emissions they produce. By utilizing stem cells from Japanese Wagyu cows, scientists from Osaka University have been able to 3D print synthetic meat complete with marbling that closely resembles the real thing. The team used two types of stem cells called bovine satellite cells and adipose-derived stem cells, which under the right conditions, can be manipulated to match the types of cells needed to produce the meat. Individual fibers including muscle, fat, or blood vessels were fabricated from these cells using bioprinting. The fibers were then arranged in 3D, following the histological structure, to reproduce the structure of the real Wagyu meat, which was finally sliced perpendicularly, in a similar way to the traditional Japanese candy Kintaro-ame.“By improving this technology, it will be possible to not only reproduce complex meat structures, such as the beautiful sashi of Wagyu beef, but to also make subtle adjustments to the fat and muscle components,” senior author Michiya Matsusaki says. This would make it possible for consumers to customize the contents of their meat in line with health considerations as well as their desired fat content and taste.Image: Science Blog #meat #alternative #sustainability #wagyu #beef #japanese #bioprinting #stemcells

Brain Organoids Spontaneously Generate Eye Structures That Respond To Light Researchers from the University Hospital Düsseldorf have found a way to study the different aspects of human brain development and diseases. Using human induced pluripotent stem cells (iPSCs), experts can generate brain organoids that can produce different cell types in the body.Previously, researchers used embryonic stem cells to generate the optic cup, which gives rise to the retina, but never managed to integrate them into brain organoids. Jay Gopalakrishnan and his team have managed to grow brain organoids that spontaneously develop optic cups. Their work is the first to generate and integrate eye structures into brain organoids. According to him, “these organoids can help to study brain-eye interactions during embryo development, model congenital retinal disorders, and generate patient-specific retinal cell types for personalized drug testing and transplantation therapies.”Image credit: Elke Gabriel #Science #BrainOrganoids #StemCells #InducedPluripotentStemCells #Retinas #OpticCups #LabCreatedEyeStructures
