"The fascination of humans with the notion of multiple personalities (and morphologies) is perhaps best captured in Robert Louis Stevenson's 1886 tale of the Strange Case of Dr Jekyll and Mr Hyde. Land plants have been pulling off this trick for 475 million years, although perhaps to less acclaim." (...) více zde >

"Japanese study of induced pluripotent stem cells aims to demonstrate safety in humans." více zde >

The advantages of using induced pluripotent stem cells (iPSCs) instead of embryonic stem (ES) cells in regenerative medicine centre around circumventing concerns about the ethics of using ES cells and the likelihood of immune rejection of ES-cell-derived tissues. (...)" více zde >

"Mouse primordial germ cells (PGCs) undergo sequential epigenetic changes and genome-wide DNA demethylation to reset the epigenome for totipotency. Here, we demonstrate that erasure of CpG methylation (5mC) in PGCs occurs via conversion to 5-hydroxymethylcytosine (5hmC), driven by high levels of TET1 and TET2. (...)" více zde >

"Although recent studies have revealed that heart cells are generated in adult mammals, the frequency of generation and the source of new heart cells are not yet known. Some studies suggest a high rate of stem cell activity with differentiation of progenitors to cardiomyocytes1. Other studies suggest that new cardiomyocytes are born at a very low rate.

"When the term neuroglia (“nerve-putty”) was introduced by the German pathologist Rudolf Virchow in 1856 (1), it was like a stigma, distracting any reputable neuroscientist from doing research on these cells. (...)" více zde >
