Although stem cell therapy has great promise, several obstacles have prevented its broad clinical adoption. The effectiveness of therapy has been inhibited by problems such as ineffective stem cell differentiation, low post-transplantation survival rates, and restricted control over stem cell behaviour. Furthermore, the implementation of stem cell therapies is further complicated by the possibility of immunological rejection and cancer. Innovative strategies that provide precise control over stem cell characteristics and maximize their therapeutic potential are desperately needed to overcome these obstacles. Recent studies have shown that the effectiveness of stem cell treatments can be greatly increased by nanoscale advances. By establishing an ideal microenvironment and precisely offering growth factors, nanomaterials such as nanoparticles, nanocomposites, and quantum dots have been demonstrated to improve stem cell differentiation and proliferation.
