For a typical dividing mammalian cell, growth occurs in the G1 phase of the cell cycle and is tightly coordinated with S phase (DNA synthesis) and M phase (mitosis). The combined influence of growth factors, hormones, and nutrient availability provides the external cues for cells to grow.and if u want to know does it grow in size Body tissues grow by increasing the number of cells that make them up. ... When cells become damaged or die the body makes new cells to replace them. This process is called cell division. One cell doubles by dividing into two.
The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.
