A stroma is the connective, part of a cell, organ or tissue. The  function of a stroma is to hold the cell, organ, or tissue together  and help it maintain form. Edit.
The functions of tumor-suppressor proteins fall into several categories including the following: 1  Repression of genes that are essential for the continuing of the cell cycle. If these genes are not expressed, the cell cycle does not continue, effectively inhibiting cell division. 2  Coupling the cell cycle to DNA damage.
