摘      要：The development of injectable bone substitutes(IBS)have obtained great importance in the bone re-generation field,as a strategy to reach hardly accessible defects using minimally invasive techniques and able to fit to irregular *** this scenario,the association of injectable hydrogels and bone graft granules is emerging as a well-established ***,in situ forming hydrogels have arisen as a new IBS *** in situ forming and injectable dextrin-based hydrogel(HG)was developed,aiming to act as a carrier of granular bone substitutes and bioactive *** this work,the HG was associated to a granular bone substitute(Bonelike)and implanted in goat critical-sized calvarial defects(14mm)for 3,6 and *** results showed that HG improved the han-dling properties of the Bonelike granules and did not affect its osteoconductive features,neither impairing the bone regener ation *** multipotent mesenchymal stromal cells from the umbilical cord,extracellular matrix hydrolysates and the pro-angiogenic peptide LLKKK18 were also combined with the *** bioactive agents did not enhance the new bone formation significantly under the conditions tested,according to micro-computed tomography and histological analysis.
