    Introduction The current method of cell expansion using T25 flasks for human embryonic stem cells (hESCs) have been proven to be extremely time and space consuming‚ labour intensive and difficult for scale-up (Minimal of 200 T25 flasks needed). It is estimated 2.8x108 - 5.6x108 undifferentiated hESCs are required by the end of the expansion stage for the process to work‚ as at least 5x107 cells of well differentiated post-mitotic Nrl+/Crx+ precursors are needed for transplant (Maclaren et al‚ 2006)

    The nucleus is a large membrane bound organelle. Most cells have a single nucleus though skeletal muscle can have more than one (multinucleate) or some cells such as red blood cells have no nucleus. The nucleus contains the genetic material and is where DNA replication and RNA transcription occur. The nucleus is bound by a membrane which contains nuclear pores. These pores allow RNA molecules and proteins to move in and out of the nucleus. However‚ this process is selective and is energy dependent
