Induced pluripotent stem cells (iPSCs) offer the possibility to accelerate tissue reconstruction through cell differentiation. The use of iPSCs in bone tissue engineering is promoted by next generation scaffolds which guide bone tissue repair and provide specific cues and molecular recognition to enhance differentiation as well as the bone forming ability of these cells. However, bone tissue repair faces additional challenges such as requirement for a consequent bone vasculature and exhaustion of stem cells in the aging adults. In this context, iPSC reprogramming seems to be unaffected by age and they have better pro-angiogenic potential as well as proliferation rate. The benefits of iPSCs using polymeric scaffolds include access to humanized in vitro models, triggering bone tissue reconstruction through a supply of bone cells via differentiation, compensating mesenchymal stem cells age-related deficiencies in osteodegenerative diseases, and enhancing angiogenesis.
