Furthermore, comparing the expression levels of different marker genes for hepatic stellate cells (HSC) and myofibroblasts (Gfap, Acta2) or Kupffer cells (Emr1), in liver tissue from SAC-WT mice and SAC-KO mice revealed no major changes in the cellular composition.
Cultivation of LSK cells on OP9 resulted in a high percentage of CD19+B220+ cells and Figure 2) and even though the addition of FL and IL7 did not have a major impact of the cellular composition of the cultures), the cell numbers were increased (Data not shown).
However, the cellular composition and major cellular fractions are greatly influenced by storage and culture conditions and cell age.
Therefore, it is of major importance to standardize the cellular composition of endometrial grafts in order to increase the validity and reliability of pre-clinical rodent studies in endometriosis research.
The biomass function was based on the experimentally measured composition of major cellular constituents during exponential growth of yeast cells and was reformulated to include trace amounts of additional cofactors and metabolites with the assumed fractional contribution of 10-6.
Therefore, changing cellular composition is a major confounder when assessing DNAm changes, and, in response to this, statistical methods aimed at dissecting this cellular heterogeneity have recently emerged (22, 26).
The majority of tissues contain macrophages as part of their normal cellular composition and TAM are also a major cell type in most cancers where they can facilitate tumor progression [ 33, 42, 157, 158].
Variation of gene expression within tissues reflects their heterogeneous cellular composition, and is also a major factor contributing to variation in gene expression.
Age-related alterations in the cellular composition of the B lineage are a major cause of the poor antibody response to vaccination and to infectious agents among the elderly population.
To test for differences in the cellular composition of Idd9 islet infiltrates we quantified the major leukocyte populations present in the infiltrate of age-matched 12 14 week old Idd9 congenic and NOD mice by flow cytometry.
