The second factor is the cessation of cell division in adult organisms, which leads to the inability to restore cellular structures. The third factor is the feature that cells do not die due to the accumulation of harmful changes that occur in the cells during the life of the organism. The fourth factor is the inability of stem cells to regenerate tissue by replacing such cells with new ones, because somatic cells do not die and there are no signals that stimulate the proliferation of stem cells and their differentiation into new ones that would replace dead cells. The fifth factor is that all cells die suddenly, due to the cessation of one of the vital functions of the organism, and not gradually during life, due to a decrease in the functionality of cells caused by the introduction of harmful changes in cellular structures, which would allow stem cells to regenerate tissues and keep the body young.
