Abstract: Stem cells are defined as cells with the capacity for self-renewal, clonogenicity, and differentiation into a variety of cell lineages. Everyone has stem cells, from the earliest stages of human development to the end of life. The potential of stem cells to differentiate in different cell lines can be categorized into five main groups, totipotent, pluripotent, multipotent, oligopotent, and unipotent. Our brains, bones, muscles, nerves, blood, skin, and other organs all require them for proper growth, maintenance, and repair. Using stem cells to give consistent, reliable therapeutic interventions......
Key word: difficulties, tissue regeneration, cell-based therapeutics, and stem cells.
