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
  • 5/11
    • 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 in mouse ES cell freezing medium (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)
  • 5/26
    • Change medium of all the P7 InsACGGsAlov3 cells.
  • 5/28
    • Passage one well of 1:12 P7 InsACGGsAlov3 mESCs into 1:6 (1 well) and 1:12 (1 well).
  • 5/30
    • Change medium of all the P8 InsACGGsAlov3 cells.
  • 5/31
    • Frozen down 3 vials of P8 InsACGGsAlov3 (from one 1:6 well).
  • 6/1
    • Passage one well of 1:12 P8 InsACGGsAlov3 mESCs into 1:6 (1 well) and 1:3 (1 well; on 0.1% gelatin coating plate without MEF feeder cells; add MEF conditioned media)
Seed cells without MEF to test the proliferation ability of InsACGGsAlov3 cells under feeder free culture system.
