“This suggests that, despite the years that have passed, cell activity can still happen and parts of it can be recreated,” said study author Kei Miyamoto from the Department of Genetic Engineering at Kindai University.

Five of the cells even showed highly unexpected and very promising results, namely signs of activity that usually only occur immediately preceding cell division.
