Embryonic Stem Cells Can Alter Cancer Cells’ Growth Conditions
Researchers at Northwestern University have been able to “reprogram” malignant melanoma to revert to normal skin cells after being in a laboratory culture previously occupied by human embryonic stem cells. The stem cells did not interact directly with the cancer cells. According to the article on Medical News Today,
The team applied two different hESC lines, independently, onto three-dimensional collagen matrices and allowed the cells to form colonies and precondition their microenvironments for several days. The hESCs were removed and the matrix microenvironments were left intact. Then, human metastatic melanoma cells were seeded onto the hESC-preconditioned matrix microenvironment and were allowed to emain for several days.The research suggests that the microenvironments which support stem cells can influence tumor development. A microenvironment is defined by the National Cancer Institute as “Local and systemic architecture surrounding a cancer cell. Includes other cells, growth factors, enzymes, and parts of the blood and lymphatic systems.” My biology is not entirely up to snuff on understanding the details of what happened, but it appears that the stem cells altered the growth factors, enzymes, and other conditions of the environment in such a way as to affect the cancer cells.

what the crap is the controvercy about every one saying that killing embryos is bad you dont even have to do that you can get stem cells from a new borns umbilical cord and they are just as good i mean really what the crud
Well, Kyle, the reason that you may be confused is because you do not understand the science. Stem cells from umbilical cords are not the same. If they were, you are right, there would be no controversy.
Karen
Ok then Karen...
Since you seem to know.. why don't
you explain the science so we will all understand..
I don't get it either.. you are using CELLS... my mother and father died from cancer,...and scientist are finding breakthroughs to help the LIVING PEOPLE? You know what I think? I think if they do find cures for Parkinson, Diabetes, and other diseases it would help a lot of people. And heaven forbid we do that! We would be taking money away from the Big Doctor's and Insurance Companies and Drug Companies then because they wouldn't have that financial security they have from all the people they gouge money from for their prescriptions and doctor visits.. It would be cut down if we found cures!!! These are CELLS NOT BABIES! We need to help our LIVING SICK people!!
