Coral landscapes can be re-generated with the help of probiotics. Using the body’s stem cells for bone grafts sometimes leads to complications or disease transmission.
But the alternative – so-called xenograft materials from mammalian tissue – is both ethically and environmentally problematic.
Which explains why a research team from Oslo has developed a sustainable solution, using eggshells.
As well as calcium and phosphorus these also contain magnesium and strontium, which stimulate bone regeneration.
Using a special method, the shells were freed from endotoxins (bacterial waste) and converted into calcium-phosphate particles.
During lab tests, the particles interacted well with the body’s bone-growing cells and immune system.
