If we make skin and muscle cells when we heal cuts and heal/generate bones after breaking them, why wouldn’t we be able to grow a finger if one is cut off?

The cells we have are not pluripotent (plants have cells like these which is why you can grow a whole plant from a price of it). Pluripotent cells contain all the instructions (dna) to make an entire organism. Our cells are specialized meaning each cell type has very specific instructions for specific functions (white blood cells cannot act as a liver cell).
