    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)
