Originally developed 50 years ago for applications in contact with bone, e.g. as bone substituting and bone filler materials, bioactive glasses (BGs) are being increasingly considered in the tissue engineering field, being investigated both in bone and soft tissue regeneration approaches. The key property enabling such applications in soft tissue repair, e. g. wound healing, is the ability of BGs to enhance vascularization via the action of ionic dissolution products (biologically active ions) [1, 2]. Silicate, phosphate and borate BGs, also combined with biopolymers forming biodegradable composites, will be discussed based on in vitro and in vivo studies in relation to hard and soft tissue regeneration. A variety of bone tissue scaffolds exhibiting highly interconnected pore structure can be fabricated by the traditional polymer replica technique or by additive manufacturing methods. The relatively low mechanical properties of such (highly porous) scaffolds can be counteract by coating the 3D porous structures with natural or synthetic polymers, so that the scaffolds achieve malleable characteristics. The coating and infiltration of scaffolds by biodegradable polymers will be discussed showing a variety of recent results, which highlight that not only the structural integrity of scaffolds is improved but also the scaffolds become “multifunctional” by the addition of ion doped inorganic nanoparticles, e.g. mesoporous particles, as drug carriers . Moreover in-vivo result demonstrating the vascularisation potential of new bioactive glasses will be discussed. In the emerging field of BGs for soft tissue engineering, an overview of their applications in contact with soft tissues will be presented focusing on our current work on Boron containing BGs (borosilicate and borate glasses) with different degradation behaviour and biological activity for hemostasis and skin repair.
