검증된 단계별 안내1
Understand the definition of an unspecialized cell: it is a cell that has not yet developed into a specific cell type with a specialized function.
Recognize that stem cells have two key properties: the ability to self-renew (make copies of themselves) and the ability to differentiate into various specialized cell types.
Compare the options: red blood cells, skeletal muscle cells, and neurons are all specialized cells with specific functions and do not have the ability to self-renew or differentiate.
Identify that the only cell type listed that is unspecialized and can both self-renew and differentiate is the stem cell.
Conclude that the correct answer is 'Stem cell' because it fits the criteria of being unspecialized and capable of both self-renewal and differentiation.
