Method description

Isolation Femoral and tibial bones are isolated from 10-12 weeks old C57BL/6J mice. After cutting the bone's ends, the bone marrow is flushed out using a 23G syringe with PBS into a 50ml falcon tube. After centrifugation cells are re-suspended in FCS (0.5ml/mouse leg). Differentiation 0.5ml of the cells suspension is added to 20ml BMM medium (15% LCM, 10% FCS and 0.5% P/S in RPMI1640) in a 20cm petri dish. After 5 days of culture all medium is replaced by 20ml fresh BMM medium. On day 7 cells can be plate out for experiments.

Lab equipment

  • - 5% CO2 Incubator ;
  • - Centrifuge ;
  • - Dissection material.
Method status
  • History of use

Pros, cons & Future potential

Advantages
  • - High amount of cells per isolation ;  
  • - Possibility of freezing the cells for future use after isolation ; 
  • - Reproducibility.
Modifications

If the cells are confluent at day 5, instead of discard the BMM medium you can place it into a new petridish to increase the amount of cells.
