Technology is quickly gathering tools to help in characterizing the cell surface antigens or the RF's (recognition factors) that play a central role in cancer.

We will create molecules that will "label" a cancer cell as producing certain CSA/RF's. Once we know where the cancer cell is in terms of it's present programming (remember, the existing CSA/RF is indicative of the particular cancer "stage"), we can present the cell with embryonic RF's that may alter the cell's behavior.

This article was recently published in PLOS. This is a great scientific publishing medium that doesn't charge anyone a cent to read their stuff, unlike Science and Nature and the others that hoard their publications at the expense of humanity. Anyway, the article points out that a boy being treated with stem cells for a rare genetic condition developed tumors of the brain and spinal cord. These results should come as no surprise for readers of this blog. The cells injected into the nerve tissues were allografts--they were obtained from a source other than the patients own tissues. These clearly will not be at home in another person's body and they will begin to express embryonic Cell Recognition Factors in the hope that they could establish communication. As we have learned here, a cell must know exactly where it is. Such communication must exist. If it does not, it would mean that A) any manner of invader could easily make its home in another multicellular organism, or B) any...

What about the unattached cell?

While this procedure is not what I had in mind when I spoke of being able to reprogram the cancer cell, I'm nevertheless glad that reprogramming was found to be possible for the unattached cancer cell. The unattached immune cell is needed everywhere in the body and it would make sense for a cancer derived from an immune cell to differentiate into other immune cells as needed. This is what was found by the Stanford researchers--reprogramming of leukemia cells into normal granulocytes and macrophages via supplied ligands or transcription factors. The initial observation from Stanford came about as a result of a shotgun approach. This approach should also be used for the solid tumor and if their cocktail doesn't do it, I would consider extracting Embryonic Cell Surface molecules from various developmental time points. Finding the right CRF for the differentiation of  solid tumors is right around the corner. My next post will be one showing what the CRF theory helps explain wh...
