Final answer:
Cultured mouse fibroblasts can be reprogrammed to become specialized cells.
Step-by-step explanation:
Cultured mouse fibroblasts can be reprogrammed to become specialized cells. In a laboratory setting, it is possible to induce stem cells to differentiate into specialized cells by changing the physical and chemical conditions of growth. Several sources of stem cells are used experimentally and are classified according to their origin and potential for differentiation.
