What would happen without cell differentiation?

Without cell differentiation, the cells and the body would be adversely affected in several ways. Anaplastic cells found in malignant tumors are undifferentiated and lack specialized functions. They exhibit a loss of the typical structural and functional differentiation seen in normal cells. This lack of differentiation is a critical aspect of aggressive and rapidly growing cancer cells. Additionally, without cell differentiation, all cells would stay the same and lack the ability to carry out specific tasks necessary for the proper functioning of tissues and organs in the body. Cell differentiation also plays a critical role during embryonic development by regulating the creation of different structures. Without this process, embryos might undergo improper development, resulting in significant abnormalities during growth or, in severe cases, being nonviable and unable to survive. Specialized cells are also necessary for repairing injuries or damaged tissues. If cell differentiation doesn't occur, the body's ability to regenerate and heal damaged tissues would be severely impaired. Lastly, differentiated cells form tissues and organs, each with distinct roles. Without differentiation, tissues and organs will not form correctly or function properly. For instance, muscles wouldn't contract and nerves wouldn't transmit signals.
