What medium and which cytokines are recommended for Natural Killer (NK) cell culture?

For the cultivation of Natural Killer (NK) cells we recommend using the X-VIVO 15 medium.In regard to cytokines, this varies depending upon the application, but many cited publications indicate using IL-2 for activation and longer term culture.

Do Lonza's NK cells proliferate in culture?

Publications indicate that IL-2 and IL-21 can stimulate NK cell proliferation in addition to using a human serum supplemented medium.

Do I need to use a gelatin, fibronectin, collagen, or Matrigel coating when culturing my Clonetics Cells?

Most Clonetics™ Cells do not require an extracellular matrix when grown on tissue culture treated plastic – flasks, dishes, well plates (with the exception of hepatocytes, and the rat/mouse neuronal and dorsal root ganglion neurons, rat cardiac...

Your instructions for culturing of Clonetics Cells do not mention centrifuging the cells upon thawing. Won't the DMSO kill the cells?

We have seen on multiple occasions that the effects of centrifugation can be significantly more damaging than the effects of residual DMSO on primary cells. As such, unless specifically noted in the recommended culture protocol, instead of...

Are Lonza's Natural Killer (NK) cells adherent in culture?

Resting Natural Killer cells grow in suspension, however, when IL-2 is added to the culture, they will adhere.

I thawed and plated my ampoule of Clonetics Cells yesterday and most of the cells are floating. What happened?

Clonetics™ Cells will not be confluent on day one. After 24 hours, you will see few attached cells per field under the microscope. Aspirate off the media and the floating cells and replace with fresh, pre-warmed media. Those attached cells will begin...

I've had my Clonetics Cells in culture for a few months, they're no longer growing and don't look like healthy cells, what's wrong?

All Clonetics™ Cells are primary cells with a finite life span. Most Clonetics™ Cells are guaranteed for 10 – 15 additional population doublings, which equates to about 2 – 3 passages. As cell death begins to occur, morphology and cell performance...

What growth factor is pertinent in chondrogenic differentiation of mesenchymal stem cells?

TGF-B3 has worked best in our hands so that is what we recommend.

Are there any substitutions that can be used in place of the HSA in the freezing media for hMSC's (Human Mesenchymal Stem Cells)?

Cryopreservation may compromise cell quality and performance. Lonza CANNOT guarantee performance of Clonetics™ & Poietics™ Cells that have been cryopreserved outside of Lonza. To avoid loss of cells and forfeiture of your warranty, we recommend...

Should any type of extracellular matrix be used when growing undifferentiated hMSC's (human Mesenchymal Stem Cells)?

That will depend on the type of medium used. If you are using our MSCGM™ BulletKit™ PT-3001, we do not recommend using a matrix with the cells as it might induce differentiation and make the cells difficult to detach from the culture vessel. If you...
