A new method to reprogram human cells to better mimic embryonic stem cells

  • Australian scientists have developed a new method called TNT reprogramming to make human cells act more like embryonic stem cells.
  • The method aims to erase the cell's memory and reduce differences between induced pluripotent stem (iPS) cells and embryonic stem (ES) cells.
  • This breakthrough could advance cell therapies and biomedical research, according to the researchers.

Reactions

  • Researchers have devised a new method to reprogram human cells, making them more similar to embryonic stem cells and potentially improving induced pluripotent stem cells (iPSCs) for research purposes.
  • The conversation delves into the possibility of using drugs to address health issues resulting from unhealthy lifestyles, as well as the impact of obesity on cancer rates.
  • There is a discussion about preserving stem cells for medical interventions, extending human life, and ongoing research on halting aging and reversing its effects.
