“Signature in the Cell is a defining work in the discussion of life's origins and the question of whether life is a product of unthinking matter or of an intelligent mind . In Signature in the Cell, Dr. Stephen Meyer shows that the digital code embedded in DNA points powerfully to a designing intelligence. If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory.
The latter simply adds the date of the signature to the signature box. Note that this is the date that the document is signed, not the date that you create the signature box. Click "OK" to add the signature box. Adding the Signature 1. Open the Excel document needing a signature if it's not open already. Then open the "Sign" dialog box by either double-clicking the signature line or by right-clicking it and selecting "Sign. Add your signature. To do this, type your name beside the "X" to add a text signature.

Another key factor in ES cells, Sox2, was implicated in lung and esophageal squamous cell carcinomas; but the induction of Sox2 in a lung adenocarcinoma cell line promoted squamous traits rather than pluripotency-related characteristics.
This suggests a role for Sox2 as a lineage-survival oncogene rather than as a stemness marker [ 60 ]. Our recent work has shown that the core module, which relates to ES cell core factors, is not significantly enriched in human epithelial tumors [ 20 ].
Thus, the contribution of ES-cell-specific core factors to tumor formation or maintenance is still uncertain. Implications for cancer and medicine The extent to which the study of pluripotent ES cells has provided insights into cancer is remarkable. In addition, the involvement of both oncogenic and tumor suppressor pathways in somatic cell reprogramming suggests that continued study of the relationship between ES cells and cancer cells is worthwhile.
In this section, we discuss how ES cells might be used to accelerate the translation of basic findings into clinically relevant tests and new therapeutic approaches. Classically, cancer cell lines have been employed as convenient biological models when investigating the characteristics of various cancers and as a platform for exploring the activity of chemotherapeutic agents.
Cell lines are not usually a preferred platform for drug screening because they often represent highly selected subpopulations of cancer cells, with accumulated genetic mutations or abnormalities acquired during long-term culture.
The shared signatures of ES cells and cancer cells suggest, however, that ES cells could provide an alternative system for studying pathways relevant to cancers. One strategy is depicted in Figure 1. Subsequently, selected modulators could then be re-validated in cancer cells either in culture or in various transplant protocols.
A variation of this theme is the recent application of gene expression signatures to identify drugs that target specific signaling pathways such as those for Ras, Src, and Myc [ 64 — 66 ].

An activated core module involving Oct4 and Nanog is specific to ES cells. A particularly powerful approach is now afforded by an elegant in silico method based on the 'Connectivity Map' [ 67 , 68 ]. The Connectivity Map encompasses an expanding database of gene expression profiles from a collection of reference cell lines treated with 'perturbagens' [ 69 ]. Click the drop-down arrow below the "Signature Line" option within the "Text" group.
In the menu that appears, click the "Microsoft Office Signature Line. Fill in the necessary information in the Signature Setup box that appears.
You can add the suggested signer's name, the suggested signer's title, the suggested signer's email address and any instructions to the signer.
You can leave any or all of these blank, but information about the document and the needed signature may be unclear to others viewing the document. Select the final options for the signature. You have two options with check boxes beside them that read "Allow the signer to add comments in the Sign dialog box" and "Show sign date in signature line.
The latter simply adds the date of the signature to the signature box. Note that this is the date that the document is signed, not the date that you create the signature box.
