• We are working with PromoCell MSCs and MSC Adipogenic Differentiation Medium. Do you have any information on a comparison between Sudan III and Oil Red O and if Sudan III is more efficient at labeling lipid vesicles?

  You can also use Oil Red O to stain lipid droplets.  At PromoCell, we used to use Oil Red O as well, but switched to Sudan III some time ago for organizational reasons.

• How long do I need to activate my macrophages? Can I stop adding activation factors after 24 hours?

  The activation of macrophages as such is complete after 24 hrs. However, to maintain the activation status over a longer period of time (i.e., several days), fresh activation factors should be added with every medium change.

• What is the difference between PromoCell NHEK and NHEK GM3?

  The NHEK (primary human keratinocytes) are isolated in our serum-free Keratinocyte Growth Medium 2 (C-20011), the NHEK GM3 in our improved serum-free and BPE-free Keratinocyte Growth Medium 3 (C-20021). Both, NHEK and NHEK GM3 are available from single or from pooled donors isolated from the epidermis of juvenile foreskin or adult skin.

• Will my NHEK (isolated in PromoCell Keratinocyte Growth Medium 2) grow in PromoCell Keratinocyte Growth Medium 3?

  Yes, the NHEK-GM2 (C-12001, C-12003, C-12005, C-12006) also grow in PromoCell Keratinocyte Growth Medium 3 (C-20021). Using the protocol with the fixed intervals, they grow slightly faster than in Keratinocyte GM2 and proliferate for > 15 PDs.
  Conversely, NHEK-GM3 (C-12011, C-12013, C-12015, C-12016) also grow in the existing Keratinocyte Growth Medium 2 (C-20011). When using the classical subcultivation protocol (density > 70% – 90%), they grow slightly slower compared to Keratinocyte GM3, but also reach > 15 PDs.

• I would like to differentiate hMSC into bone cells and further maintain the cells in culture after differentiation. Which medium should I use?

  Osteogenic differentiation of hMSCs with PromoCell MSC Osteogenic Differentiation Medium takes ∼12-14 days (please view the respective Application Note for a detailed protocol). Use fibronectin-coated plates and change the medium every third day.

  The bone cells tend to detach from the plastic after approximately 2 weeks, when differentiation is complete. Therefore, the tests should be performed promptly and the cells should be maintained in MSC Osteogenic Differentiation Medium until then.
