A megamaser is a type of astrophysical maser, which is a naturally occurring source of stimulated spectral line emission.
When used as feeder layer sto support the culture of normal bone marrow cells, the peripheral blood leucocytes of untreated patients are a uniformly poor source of colony stimulating factor (CSF) and fractionation experiments suggest that this is not due merely to a relative scarcity of monocytes.
Cells were maintained at 37 °C and 5% CO2 in DMEM supplemented with 10% fetal bovine serum, 0.5% penicillin/streptomycin, 4 mM ℒ-glutamine, and 20% conditioned medium from bone-marrow-derived Ladmac cells (ATCC CRL-2420) as a source of colony stimulating factor-1.
If 2G biomass were sourced by felling of forests, or where the use of marginal land which is in fact a source of food stimulates indirect land use change (iLUC) effects, then the GHG balance may be questioned.
Cells were maintained at 37 °C and 5% CO2 in DMEM supplemented with 10% fetal bovine serum, 0.5% penicillin/streptomycin, 4 mM l-glutamine and 20% conditioned medium from bone-marrow-derived Ladmac cells (ATCC CRL-2420) as a source of colony-stimulating factor-1.
Several observations support the suggestion that apoptotic tumor cells may serve as a potent source of antigen for stimulating host immune responses in vivo.
Fresh or frozen bone marrow cells were used to generate BMDM as previously described [8], using L929-cell conditioned medium (LCCM) as a source of granulocyte/macrophage colony stimulating factor [9].
Terminal granulocytic differentiation was induced by removing IL-3 and SCF and adding 10% BHK-HM5 CM as a source of granulocyte/macrophage-colony stimulating factor (GM-CSF).
These cells were cultivated in RPMI 1640 media (Gibco, Life Technologies) supplemented with 20% heat-inactivated fetal calf serum (Gibco, Life Technologies), 1% of penicillin and streptomycin (Sigma-Aldrich) and 30% of L-Cell Conditioned Media as a source of Macrophage Colony Stimulating Factor (M-CSF) for 7 9 days.
