Reagent#

  • iPS cells

  • mTeSR plus (Stem cell technolgies, culture meidum)

  • Matrigel ESC qualified

  • ReLeSR™ Human PSC Selection & Passaging Reagent (Stem cell technolgies,)

  • Y-27632 (Rock inhibitor)

  • CryoStor CS10 | freezing solution (Stem cell technolgies,)

Protocols#

Thawing cells from freezing cells

  1. Thawing matrigel stock solution on ice (1.5 ml tube)

  2. Add cold 10ml of DMEM/F12 into 15ml of falcon tube.

Important

Must use cold DMEM/F12

  1. Add Matrigel solution into prepared 10ml of DMEM/F12 in 15 ml falcon tube

  2. Coat 6 well late with Matrigel , and incubator for one hour at RT

    • 6 well plate: 1 mL per well

Important

Do not put into incucator

  1. Thawing the cells in freezing vial (from LN2 Tank) at 37C water bath

  2. Add 4 ml of mTeSR plus new 15 ml falcon tube.

  3. Add 1 ml of cell suspention from freezing vial into 15 ml of falcon tube.

  4. Centrifuge 15ml of falcon tube at 1000 rpm for 3 min at RT.

  5. Aspirate supernatant

  6. Add 2 ml of fresh mTeSR plus into 15 ml of falcon tube containing cell pelet. Pipette and mix for several times.

Important

Do not mix more than 5 times, use 5 ml of pipette

  1. Transfer cell suspension to 6 well plate

  2. Place 6 well plate into incubator.

Medium change

  1. Aspirate mTeSR plus from 6 well plate

  2. Add 2 ml of mTeSR plus into 6 well plate

Subculture

  1. Aspirate culture medium from 6 well plate

  2. Add 1ml of ReLeSR™ into 6 well plate

  3. Aspirate ReLeSR™ from 6 well plate

  4. Incubate the plate for 3-5 min

  5. Add flesh 1 ml of mTeSR plus, and then tapping the plate for 10-30 sec until you can see floating cells and to get 30-50 um of cell colony.

  6. collect all soulstion into a 15mL falcon tube.

  7. Add 7 ml of mTeSR plus into falcon tube.

  8. 2 ml of cell suspension into Matrigel coatd 6 well plate

  9. Place 6 well plate on incubator.
