                                        Stem cell bioengineering addresses regenerative medicine and cellular therapies
                                        by applying advanced techniques to stem-cell-derived systems. Despite their
                                        promise, stem cell applications are limited by incomplete knowledge. Stem cells and
                                        phytochemicals show potential in treating diabetes by halting β-cell degeneration
                                        and promoting endogenous islet regeneration. Current diabetes cell therapies
                                        include stem cells, mature pancreatic cells, endocrine progenitors, and β-cells, with
                                        researchers actively seeking new cell sources for clinically relevant β-cells. Stem cell-
                                        derived pancreatic cells are particularly promising for pancreatic islet regeneration.
