Background/Objectives: Stem cells with the ability to differentiate into other cell types and self-renewal afford a powerful apparatus for the healthcare system to replace and rejuvenate damaged tissues and organs in the treatment of various diseases. For the last few decades, stem cell therapy (SCT) has evolved from being an experimental approach to a recognized clinical treatment. SCT and regenerative medicine have garnered tremendous attention and become prominent tools, especially in treating chronic and acute disease and addressing organ failures, and in their repair and replacement, which are directly associated with human health, life, and longevity. Methods: In this review, after providing a brief history and need for the SCT, the employed delivery techniques utilizing various biomaterials, as well as recent developments in nanotechnological methods, are presented.
