  • If an inner cell mass is taken from a mouse blastocyst and given the right nutrients, the pluripotent cells can grow in the laboratory. (eurostemcell.org)
  • These laboratory-grown cells are called embryonic stem (ES) cells . (eurostemcell.org)
  • Adult stem cells supply new cells as an organism grows and to replace cells that get damaged. (yourgenome.org)
  • In the cell, those "new parts" are proteins, the building blocks of any organism. (ucsf.edu)
