AI Summary

Researchers at the University of Oslo harvest skin cells from lab workers, who develop distinctive round or cross‑shaped scars after the sampling. The cells are cultured and then reprogrammed into induced pluripotent stem cells (iPS cells), which can divide indefinitely and differentiate into muscle, blood, nerve or other specialized cell types. These iPS cells are being explored for potential new treatments for conditions such as heart attacks and Parkinson’s disease.
