Cells are constantly produced by cell cycle pathways in living organisms. Cells can not be replaced by any molecules or drugs as cells are units of life that forms tissues and subsequently organ systems. The patient need to be treated if there is any impairment in cell division or cell cycle.
it is replaced by scar tissue because the cells all die off eventually.
Most individual cells within multi-cellular organisms have a finite lifetime. As cells wear out or die, they must be replaced by new ones. Cells in simpler organisms will reproduce by division, leaving one older cell and one newer cell.
Cell Division role is if any injury happens the cell can divide quickly and repair the open area, or cut. the human body is made up of 200 different types of cells which are replaced at different times. so if you do cut yourself the lower layer begin to divide , then new cells will fill the open area, and then the cells divide and repair the cut.
UGH~
Cells age, wear out and die. If they weren't replaced, we'd die, a lot sooner than we do today.
Without cell division we would not grow (taller or heavier) nor would we be able to replace cells as they wear out. Most cells of the human body have a life span of no more than seven yearsm so as cells die, they are replaced by similar, if not identical, new cells, created by cell division or "mitosis."
Mitosis
No to cannot live without cell division because our cells need to divide to make us grow. Also we need cell division to survive because our cells only live for a limited amount of time, so if our cells don't divide then the cells will just die and we won't survive.

Skin cells die because these cells are constantly undergoing cell division, and millions of new cells are produced daily; hence its alternate name, stratum germinativum.
Life is based on the ability of cells to reproduce, or make copies of themselves. This is done by a process called cell division = one cell divides into two cells. * For one-celled organisms, cell division = reproduction; each cell division not only produces a new cell, it also produces a new organism (bacteria, protists). * For multicellular organisms (like us) cell division allows an organism to grow and develop from a single cell to trillions of cells, and also to repair and replace cells.
cell turnover, where old cells die and are replaced by new cells. This process helps maintain the body's overall function and health.
Cancer cells are abnormal in that they do not respond to the body's internal and external symbols. When normal cells touch other cells, they stop dividing but, cancer cells don't stop dividing. They pile up causing many problems.

Damaged or diseased cell usually don't enter cell division anymore (some viruses can trigger cell division). By die from apoptose, followed by atrophy (natural programmed cell death). Fit cells can divide by mitosis. Or in the case of reproductive cells, meiosis.
No, mitosis is a form of cell division that produces two daughter cells with the same genetic information as the parent cell. This process is important for growth and repair in multicellular organisms.
