Cells thawed and plated on 24/06/09
Removed 3 vials from the dewer in the PC2 lab:
PC12T frozen by MV 22/01/98, Tube 7
B35 frozen by MH 3/10/98, Tube 19
RGC5 frozen by MS 29/11/99, Tube 5
Cell densities post-plating were:
PC12 - 70-80 at 10x magnification with clumps
B35 - 100 at 10x magnification
RGC-5 - 100 at 10x magnification
Photos and densities on 25/06/09 - 24 hours post thawing
PC12 - less than 10% survival, because wrong medium was used (DMEM f10 P/S instead of DMEM f5 h10 P/S) - this was changed in an attempt to rescue the remaining cells
B35 - about 50% survived freezedown. Mostly flat cells with neurites
RGC-5 - 40-50 at 10x magnification - about 50% survive freezedown.
Following replacement of media, photos were taken of each of the 6 plates (2 for each cell type) at each magnification (4x,10x,20x,40x). Therefore, there was a total 24 photos. They are saved on the computer and labelled as <cell line> dish <#> <magnification>. Eg. B35 dish 1 4x
Photos and densities on 29/06/09
PC12 - slowly growing, clumps of living cells starting to appear.
B35 - Confluent, need splitting
RGC-5 - Confluent, need splitting
Photos were taken of all plates as above.
Photos and densities on 30/06/09
B35 1mL replated - still quite confluent
B35 0.5mL replated - 75 cells/view at 10x zoom
RGC 0.5mL replated - 400 round cells/view at 10x zoom, with clumps of flattened cells and ?crystalline structures?
RGC 0.25mL replated - 200 round cells/view at 10x zoom, with fewer clumps of flattened cells and still some ?crystalline structures?
PC12 - still growing slowly in clumps
B35 - confluent - will split tomorrow
RGC - confluent - will split tomorrow
Cells thawed and plated on 30/06/09
Removed 3 vials from the dewer in the PC2 lab:
PC12T frozen by VC 2/05/06, Tube 4
HT4 frozen by MW 18/07/96, Tube 8
N12 frozen by CS(?) 2/10/01, Tube 1
Cells thawed and plated on 1/07/09
Removed 1 vial from dewer 1 in the G16 lab:
C17-2 frozen by MH 3/10/98, Tube 3
Photos and Densities on 3/07/09
C17-2 ~ 50 cells at 10x magnification
HT4 - confluent on both plates. One plate was split, the other left confluent over the weekend.
N12 - 40-50 rounded cells at 10x magnification. Very few flattened cells.
PC12 - 100 rounded cells at 10x zoom
B35 - Both 0.5mL dishes split on the 1/07/09 were 300-400 cells/10x magnification. Both dishes (0.5mL and 1mL) split on 29/06/09, were confluent. Therefore, only 1 dish (from the 1/07/09 pair) was split and the others were discarded.
RGC-5 - Both 1mL dishes split on 1/07/09 exhibited clumps of cells and in each clump, a density of ~ 50 cells/10x magnification. Of the two dishes split on the 29/06/09 (0.25mL and 0.5mL dishes), the 0.25mL dish was still growing in clumps, and the 0.5mL dish was potentially contaminated and was therefore disposed of.
PC12 - both dishes still growing in clumps of rounded cells.
Photos and Densities on 6/07/09
C17-2 - both dishes almost confluent. One dish was split into a 0.5mL and 0.25 mL dish.
HT4 - both the unsplit dish (2) and the split dishes (from 3/07/09) were confluent. Split Dish 1 (from 3/07/09) was split again.
N12 - very few cells at all - don't seem to be growing. Perhaps DMEM f10 media is not ideal.
B35 - All 3 split dishes (from 3/07/09) were close to confluent. Dish 1 was split again.
RGC-5 - The 0.25mL split dish from 29/06/09 is still growing in clumps across plate, as is the split dishes from 1/07/09. The newer dishes are not as dense in the clumps.
PC12 - Original plates from 24/06/09 - very very dense clumps of cells, but not confluent over entire plate. Newer plates from 30/06/09 - about 30 clumps of 5-10 cells at 10x magnification. All cells in both plates are rounded, not flattened.
Update on plates as of 7/07/09
HT4 - Split plate 1 from 6/07/09 to two new plates. Therefore, now have the two original plates (3/07/09), plate 2 (6/07/09) and two new plates (7/07/09).
C17-2 - Aplit both 6/07/09 plates. The 0.25mL one to a flask, the 0.5mL one to 2 new dishes. Therefore, now have one original plate (1/07/09), two new plates (7/07/09) and 1 new flask (7/07/09).
B35 - Split both plates from 6/07/09. The 0.25mL one into a flask, the 0.5mL one into 2 plates. Therefore, now have 2 plates (3/07/09), 2 plates (7/07/09) and 1 flask (7/07/09).
PC12 - Both non-genetically modified plates split to one flask. One genetically modified plate (24/06/09) split to two plates. Therefore, now have one original genetically modified plate (24/06/09), two split genetically modified plates (7/07/09) and one non-genetically modified flask (7/07/09).
RGC-5 - Both plates from 1/07/09 split to 4 new plates. Therefore, now have one plate (29/06/09) and four plates (7/07/09).
NT2 (previously called N12 - I think I got the name incorrect) - not growing. May change media to optimem if these cells are needed.
Also made up 2 x 24 well plates (7/07/09). Each plate contains 4 wells of each cell type except for RGC-5, which has 8 wells allocated on each plate. Due to problems splitting the non-genetically modified PC12 cells, the genetically modified cells were used for these 2 24 well plates.
Total: 22 plates, 3 flasks, 2 x 24 well plates

Update on plates as of 9/07/09 and photos of flasks
Following cell culling, growing cells consist of the following:
HT4: 2 plates split on 7/07/09 and 2 flasks split today. No pictures are provided of the flasks as they were just split minutes ago.

B35: 2 plates split on 7/07/09 and 1 flask from 7/07/09
PC12: 2 genetically modified plates from 7/07/09 and 1 non-genetically modified flask from 7/07/09
RGC-5: 3 plates from 7/07/09. Will create a flask tomorrow.
NT2: 2 plates from 30/06/09 - still not growing.
Update on cells as of 20/07/09
Tissue culture completely shut down today. All cells frozen down in storage and excess plates disposed of. All flasks harvested for DNA/RNA/Protein extraction.
