Recent studies of stem cells have played are very important because they show promise in helping man solve or at least grasp the solution to the diseases that have haunted him since his early days of conscious. The idea of stem cells is kind of a simple idea. This brings us to the first promise‚ not only are stem cells able to be taken from the human body‚ but scientists are now able to grow these cells in labs. The most worried over part is that when obtaining the cells‚ it doesn’t always

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)
