The phrase "a portion of cells" is correct and usable in written English.
It can be used when referring to a specific subset or segment of cells in a biological, medical, or data context.
Example: "In the experiment, we analyzed a portion of cells to determine their response to the treatment."
Alternatives: "a segment of cells" or "a subset of cells."
Mcl1-Venus localized to the nucleus throughout the cell cycle, and a portion of cells showed a punctate (Figure 7A, top) or condensed pattern (Figure 7A, middle) of Mcl1-Venus signal.
A portion of cells in these cultures were treated with RNAlater for quantitation of IL-9 transcripts by qt-RT-PCR, and the remainder of this cell population was resuspended in FCS supplemented with 10% DMSO (Sigma) and these cells were frozen at −80°C until flow-cytometric analysis of the phenotype.
Over 160 colonies from 12, 15, 17, and 21 days of culture were collected in each of two independent experiments; a portion of cells of each colony was re-plated at high cell density with BRL, while the remainder was collected for total RNA preparation.
A portion of cells was further propagated to reach a sufficient number for re-staining with biotinylated GD03-Fc protein and APC-conjugated streptavidin, while scFv genes from the remaining cells were rescued by PCR amplification of genomic DNA for rapid recloning and scFv DNA sequence analysis.
It is conceivable that ES cell cultures are structured hierarchically with only a portion of cells retaining full developmental potential.
Interestingly, the one exception expressed a wild type AR in a portion of cells due to somatic mosaicism (ARD465).
A portion of cell suspension (50 μl) was placed onto a glass slide, covered with a cover slip and viewed immediately using a fluorescence microscope equipped with FITC (green) and PI (propidium iodide; red) filters.
A portion of cell suspension was centrifuged, frozen and used as time 0 control sample for RNA extraction.
It is now clear that at least a portion of cell death is a regulated cell suicide process.
Unlike typical Turing patterning mechanisms, Wnt signaling in this case is intimately coupled with cell proliferation and expressed in only a portion of cell lineage within the growing tissue.
After co-transfection with two plasmids encoding the respective chimeric receptors in IL-3 dependent murine pro-B Ba/F3 cells, a portion of the cells survived under antigen dependent stimulation without IL-3.
