Also once the are converted to that specific cell type, they could even specialize themselves into a certain region, or task inside that tissue.
Cell<span> differentiation is how generic embryonic </span>cells become specialized cells<span>. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a </span>cell<span> functions
