points and chemical regulations in place to ensure that cell proliferation is controlled‚ but sometimes these checkpoints are ignored or overridden by cells and thus we see excess cellular proliferation – a good example of this is cancer cells like the HeLa S3 cells that we have been working with in the laboratory. When a cell is not regulated‚ access to the growth factors can be extremely detrimental as they allow these cells to continue growing unchecked. Thus‚ growth factors‚ which are so vital to
