Many diseases are caused or made more severe by the destruction of healthy cells in the body, making it harder or even impossible for it to perform certain functions. Parkinson’s disease, for example, occurs when neurons that produce dopamine start to break down and die, and Type 1 diabetes is caused by an autoimmune reaction that destroys the cells that produce insulin.

Since the 2010s, researchers have explored the possibility of treating these diseases with induced pluripotent stem cells (or iPSCs). These cells are made by reprogramming blood or skin cells until they start behaving like stem cells in embryos, meaning they can then be programmed to turn into basically any type of cell.

Although iPSC’s show promise in treating degenerative diseases, there is one major catch: right now, creating these cells into useful tissues is a........
