Competing Interests

Dr. Sean Thornton is participating in this research without monetary remuneration. The specimens from which the sample tissues are collectd are those for which his company, Cellnetix, is contracted indirectly to Swedish Medical Center to evaluate for clinical (medical) reasons for direct patient treatment. His company is paid for their usual patient care roles through normal (i.e., insurance and other payer) channels. No funding of the research comes from Cellnetix, Swedish Hospital or from private persons. His only compensation was through his usual and customary salary at Cellnetix. Cellnetix has no competing products, is not engaged in product development, or patenting any technology relating to this research. This does therefore not alter the author's adherence to all the PLoS policies on sharing data and materials.
