When EGF docks on a receptor, it signals to an enzyme called tyrosine kinase to regulate cell growth.
The cell growth achieved using this method led to cell growth that was 3-4 times larger than control groups.
"There is evidence that certain hormones, or growth factors such as insulin, act to stimulate cancer cell growth, " he says.
Cannabinoids may cause antitumor effects by various mechanisms, including induction of cell death, inhibition of cell growth, and inhibition of tumor angiogenesis and metastasis.

It is consistent with Gompertz's growth curves and ties together two essential features of cancer that researchers had long considered separate--cell growth and metastasis.
If the ectopic pregnancy is detected early, an injection of the drug methotrexate is sometimes used to stop cell growth and dissolve existing cells.
Previous studies have shown that GLP-1 stimulates B-cell growth in animals.
The seeded structure is placed in an incubator for about two weeks, in a "cooking" process that Atala says simulates how cell growth occurs inside the body.
These drugs--such as Herceptin for breast cancer (Genentech) and Erbitux for colon cancer (Eli Lilly)--were designed to bind to signaling molecules on tumors and disrupt cell growth signals.
Some areas identified as particularly human are the regulation of the cone cells of the retina (which are involved in colour vision) and the regulation of nerve-cell growth.
Glivec appears to shut down proteins regulating cell growth.
However, the development of reproducible methods to control stem cell growth and differentiation is still a challenge and major studies are needed before stem cells can be widely used for therapeutic purposes.
"When it comes to breast cancer risks, the extra fat in obesity leads to extra estrogen production, which can lead to extra breast cell growth, including abnormal breast cell growths, " she said.
Bristol-Myers originally designed dasatinib to block a mutant protein in other tumors, but in 2001 company pharmacologist Francis Lee noticed that it was hundreds of times more potent than Gleevec in blocking the CML cell growth.
Novartis is in final trials of a drug that may help the one-third of acute myeloid leukemia cases with a gene mutation that turns on cell-growth signals.
The upshot of all this is that the stem-cell hypothesis of cancer growth looks a good one.
Finally, the past two decades have seen an explosive growth in cell phone use from 0 to 5 billion cell phone subscriptions.

The cells themselves are programmed into a cell line using stimulation of growth techniques.
Expanding MSN's ranks may rely more on stealing customers from AOL than on landing newcomers, just as growth in the saturated cell phone and long-distance markets requires raiding rival subscriber lists.
Millennium's test detects melastatin, a skin gene that may slow cell division, and thus inhibit tumor growth.
They believe a single type of cell may be cancer's main growth engine:mutant stem cells that, though barely present, spawn other cells that then spark growth.
Besides playing to the gallery of public opinion, it is hoping that, in the long term, stem-cell technology could become an important engine of growth.
On the FDA's Fast Track and in phase III testing is the company's BAY 43-9006, a small molecule RAF kinase and VEGF inhibitor that inhibits tumor growth for patients with metastatic renal cell carcinoma (advanced kidney cancer).
