These abnormalities in turn can lead to cyst formation through at least three important mechanisms: 1  Cell proliferation (growth) â the cells lining a cyst reproduce themselves more than normal kidney cells do, making them grow in size. This process is essential to growth and replacement of the old cells.
How elements are arranged in the periodic table (General) 1  The chemical elements are arranged in order of increasing atomic number. 2  The rows are called periods and the columns are called groups. 3  Elements with similar chemical properties are in the same group of elements.
