The goals for regenerative medicine (RM) are focused on developing innovative tools in modern medicine. Recent progress has led to the development and clinical implementation of newer technologies, ranging from diagnostics to therapeutics for a wide variety of metabolic, degenerative, and infectious diseases.These include specific applications toward age‐ and genetic‐related human and animal dysfunctions and disorders. The focus of this review is to present, in a nutshell, the current status of adult stem cell therapy (CT) and tissue engineering (TE), including the challenges faced, progresses attained, and an optimistic view of the future. We will also provide our views on how the next 20+ years will potentially affect these RM‐driven innovations and how they are applied toward a variety of disease treatments, cures, and diagnostics.
