Squier describes some forms of laboratory living matter, such as stem cells, organs for transplantation, and banked embryos, as liminal lives. The common point for all of them is that they remain ‘in-between’ two bodies, two forms of embodiment (Squier 2004: 4). They travel between two organisms, and they stop in the laboratory for a shorter or a longer time. The laboratory is also the locus of the liminal transition and its time regulator.
