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)

which small quantities of Ca2+ ions were injected directly into the cell showed that an increase in intracellular calcium led to skeletal contractions. However it was not until the early 1960s when the way calcium ions were stored in cells became clearer thanks to work from Ebashi and Lipmann. (Burgoyne and Petersen‚ 1997). Calcium signalling determines whether or not a cell is activated. It is determined by calcium-ON and calcium-OFF mechanisms. Calcium-ON is responsible for pouring Ca2+ into the cytoplasm

Questions: 1. When you performed Step 2 of the procedure‚ you actually made a cylinder of M&Ms. The cylinder was rather "smushed‚" and the height of the cylinder was the thickness of an M&M. Recall that the equation for the volume of a cylinder is V = (3.14)r2h. A. Rearrange the equation for "h." Show your work.H=v*(3.14)r^2 B. Using the data from Table 1 and your equation‚ calculate the average thickness (height) of an M&M for each trial. Record your calculated values in
