Question: Could you spray stem cells onto a wound to make it heal much faster?

One day we might be able to do this, one problem we currently face is our bodies are very good at telling when a cell is not from our own bodies, so we may need to be able to extract stem cells from the patient’s body, or learn how to turn the cells in their wound to become stem cells (we can already turn skin cells into stem cells however it’s currently quite a long process, like 2 weeks, which might be too long for the patient)
