Let me Google that for you...
how do stem cells work - Google Search
"How do stem cells know what to turn into?
Cell fate means that a stem cell “makes a decision” to differentiate into a more mature cell type. Signals from the environment—chemicals, extracellular proteins/hormones/factors, neighboring cells, the physical environment—converge on the cell, typically activating a signaling cascade that leads to gene expression."
"Do stem cells regenerate your body?
Stem cells play an important role in regeneration because they can develop into many different cell types in the body and renew themselves millions of times, something specialized cells in the body—such as nerve cells—cannot do."
