This is one of the rare occasions when I treat an issue purely related to science, but when I read the article I was struck with memories from the period of roughly 1998-2005.
Firstly, a brief quote:
The novel method involves altering the signal pathways of cells specific to the human foregut – the upper portion of the gastrointestinal (GI) tract. Through this manipulation, researchers were able to stop the cells from developing fully and push them into a state of constant self-renewal.
As a result, these “foregut stem cells” can then be further amplified by physicians, who can then form them into liver or pancreatic cells. These cells could potentially be used to treat damaged organs or tissue, in addition to conditions such as type 1 diabetes or metabolic liver disease......"
