As the authors of the patent explain, no alternative materials are currently available on the market, nor have any been described in the literature. Precedents exist in the development of materials that fulfil the basic function of stimulating cell differentiation but a biologically complex material similar to bone tissue has never before been produced “ex vivo”.
Please note: If no author information is provided, the source is cited instead.
What’s more, the method of stem cell differentiation developed in Granada uses a three-dimensional support and facilitates obtaining cell types implicated in bone regeneration in cell culture conditions not requiring additional differentiation factors or factors that differ from those present in the cell culture serum. In other words, thanks to this invention, a biomaterial consisting of stem cells supported on activated carbon cloth and capable of generating a product in which osteochondrial and mineralized extracellular organic matrix lineage cells exist, can be obtained.

“Artificial bones” successfully generated from umbilical cord stem cells
Although the method has not yet been applied with ‘in vivo’ models, laboratory results are highly promising. In the future, they could help manufacture medicines for the repair of bone or osteochondrial, tumour or traumatic lesions and to replace lost cartilage in limbs. After obtaining artificial bones in the laboratory, the researchers’ next step is to implant this biomaterial in experimental animal models – like rats or rabbits – to see if it can regenerate bone in them.

The scientists, from the Biomedical Research Centre and the Faculties of Sciences of the Universities of Granada and Jaén, and the Spanish National Research Council Institute of Parasitology and Biomedicine “López Neyra”, have made this important scientific breakthrough after years of research in cell biology [1], radiobiology [2] and materials studies [3, 4].
