Work to date

Eggan's work has succeeded in developing a technique of merging stem and skin cells that has obtained considerable public attention as an a possible avenue to avoid moral objections regarding stem cell research in the context of serious illness. It suggests that ultimately, treatment of serious illnesses and understanding of stem cell development may be possible to obtain without recourse to human embryos – a highly desirable state of affairs politically, given the concurrent controversy over stem cell research in the United States.

Eggan's team reported that they had created cells similar to human embryonic stem cells without destroying embryos, a major step toward someday possibly defusing the central objection to stem cell research. These discoveries sparked extensive debate in the United States Congress

, with opponents of the use of embryonic stem cells from fetuses arguing that these or similar methods of creating stem cells from skin might be eventually used instead to satisfy the conflicting demands of medical research and morals.
"Eggan's technique provides a window into exactly what happens to turn back the clock in cells during cloning--and, indeed, in the normal process of creating sperm, eggs and embryos. Somehow, aging is reversed, and old cells become young again. As Schatten puts it, the one-way freeway of life has an exit ramp. Understanding what happens when the cell is reprogrammed is one of the main goals of studying embryonic stem cells. But right now, the only way to solve that problem is to clone embryos, which is a difficult and expensive process.


Eggan himself is cautious about his team's work, with an early stage 2005 profile in Nature

noting there was still much work to do:
The hybrids still contain two nuclei: one from a skin cell and one from an embryonic stem cell. So they have an abnormally high amount of DNA, and Eggan needs to work out how to remove the embryonic stem cell's DNA. Eggan adds that he has only just begun working with the hybrids, so it is not clear what they will or won't be able to do. "It's frustrating," Eggan says, "because they're implying that our work is a solution, which it is not yet. These are ideas in their most nascent stages."

Work as spokesperson

Forbes noted in Eggan's 2007 profile that:
"Eggan is also becoming one of science's more outspoken voices, defending the necessity of pursuing embryonic cell research through all available means as a way of understanding scourges [such as degenerative diseases]."
