mESC rainbow line expansion
- 5/2
- Received one vial of cells from Inna, and stored it in the N2(l) tank located at CERC.
- 5/3 discussed with Dr. Blue Lake in Dr. Yang Xu’s lab
- 5/7 preparing MEF with Blue
- 5/8 thawing
- Thaw cells in one 6-well plate
- 5/11
- some colonies appear to show
- 5/14 Passaging
- The culture looks ok, but there is some differentiation… so Blue passaged at several different dilutions (the lower ones to try and get rid of the differentiated cells).
- Passage one 6 well into one 1:3, one 1:4, one 1:5, and one 1:6 well.
- 5/18 Passaging
- Passage the 1:3 well into two 1:3 wells, two 1:6 wells, and one 1:12 well.
- Frozen down 3 vials of P4 InsACGGsAlov3 (from one 1:4 well, one 1:5 well, and one 1:6 well).
- 5/21 Passaging (Blue and Tina)
- 1:3 wells look very healthy; 1:6 wells look good, and 1:12 well can wait for one more day.
- Passage one well of 1:3 into 1:3 (1 well), 1:6 (1 well) and 1:12 (1 well)
- Passage one well of 1:6 into 1:3 (1 well), 1:6 (1 well) and 1:12 (1 well)
- Frozen down 8 vials of P5 InsACGGsAlov3 (from one 1:3 well and one 1:6 well)
- 5/22
- P6 cells look nice. Cells were passaged well yesterday.
- P5 1:12 well shows a few differentiated colonies, and therefore is discarded to maintain good cell quality.
- 5/24 Passaging
- Bring mESCs back to CERC. Will start to culture by myself.
- Bring back 8 vials of P5 InsACGGsAlov3 and store them in the N2(l) tank located at CERC.
- Passage one well of 1:6 P6 InsACGGsAlov3 into 1:6 (1 well), 1:12 (1 well) and 1:24 (1 well)
- Frozen down 7 vials of P6 InsACGGsAlov3 (from two 1:3 well and one 1:6 well)
- 5/25
- Passage one well of 1:12 P6 InsACGGsAlov3 into 1:6 (1 well), 1:12 (1 well) and 1:24 (1 well)
- Frozen down 3 vials of P6 InsACGGsAlov3 (from one 1:12 well and the remaining part of the passaged 1:12 well)
- Prepare 0.1% gelatin
Add 0.2g gelatin to 200mL ddH2O. Gelatin will not be soluble at this stage. Autoclave for 30 min. Gelatin will dissolve. Store at room temperature.
- Prepare gelatin coated plates
Add 1mL of 0.1% gelatin into each well of a six well plate. Put the plate in 37C incubator for 15-20 min. Plates can be stored in incubator (as long as they are not dry out). Aspirate remaining gelatin before use.
- Seed MEF on gelatin coating plates (using MEF culture medium)
- 5/26
- Change medium of all the P7 InsACGGsAlov3 cells.
- 5/28
