does it mean that the embryonic stem cell is able to go back to being unspecialised after is starts the process of specialisation?

orrrr does it mean that once it starts developing, it can reproduce a brand new stem cell so we can start experimenting again?

Self-renewal means that stem cells can divide to give rise to more stem cells. Stem cells can divide symmetrically or asymmetrically. In symmetric division, one stem cell divides to produce two new stem cells; in asymmetric division, one stem cell divides to produce one stem cell and one progenitor cell (which does NOT self-renew), which will undergo differentiation to become a terminally differentiated cell.
