Washington, Feb 24 : In a path-breaking research, scientists have discovered a way to transform skin cells into mature, fully functioning liver cells that flourish on their own.

The technique could serve as an alternative for liver-failure patients who do not require full-organ replacement or who do not have access to a transplant owing to limited donor organ availability.

Researchers at Gladstone Institutes and University of California, San Francisco (UCSF) revealed a new cellular reprogramming method that transforms human skin cells into liver cells that are virtually indistinguishable from the cells that make up liver tissue.

"Earlier studies tried to reprogramme skin cells back into a stem cell-like state in order to then grow liver cells. However, generating these pluripotent stem cells, or iPS cells, and then transforming them into liver cells was not always resulting in complete transformation," explained Sheng Ding, senior investigator at Gladstone Institutes.

"So we thought that, rather than taking these skin cells all the way back to a stem cell-like state, perhaps we could take them to an intermediate phase," he added.

Instead of taking the skin cells back to the beginning, the scientists took them only part way, creating endoderm-like cells.

Endoderm cells are cells that eventually mature into many of the body's major organs - including the liver.

This step allowed them to generate a large reservoir of cells that could more readily be coaxed into becoming liver cells.

Next, the researchers discovered a set of genes and compounds that can transform these cells into functioning liver cells.

After just a few weeks, the team began to notice a transformation.
