The phrase "aggregate cell population" is correct and usable in written English.
It can be used in scientific or medical contexts, particularly in discussions about biology, immunology, or cell research, where you refer to a collective group of cells.
Example: "The study focused on the aggregate cell population in the tumor microenvironment to understand its role in cancer progression."
Alternatives: "combined cell group" or "total cell population".
Here we report that signaling via Toll-like receptors (TLRs) induced intrahepatic aggregates of myeloid cells that enabled the population expansion of CTLs (iMATEs: 'intrahepatic myeloid-cell aggregates for T cell population expansion') without causing immunopathology.
Single-cell measurements were aggregated into 328 cell population features per experiment such as cell number, mitotic index, nuclear and cellular area, and other descriptors of shape and morphology (Supplementary file 3).
We developed an asynchronous threshold Boolean network simulation algorithm to model signal transduction in a single cell, and then used an ensemble of these models to estimate the aggregate response across a cell population.
With a series of measurements, one could effectively determine which conditions yielded more aggregate caspase activity in the cell population, but not how that activity was distributed across single cells within this population.
This leads to the hypothesis that noninvasive neuroimaging methods recording the aggregate activity of cell populations should reveal spatially overlapping responses to adjacent fingertips in areas 1 and 2, but not in area 3b.
Here we investigate a biologically motivated model for estimating tissue level responses by aggregating the behavior of a cell population.
Given that platelets have been reported to adhere to circulating tumour cells, where they can protect the CTCs from NK cell induced lysis (Nieswandt et al, 1999), it is possible that we are measuring heterocellular aggregates of platelets within the CD31+CD45− cell population via flow cytometry and this is a point warranting future analysis.
Next, on day 8 of differentiation, the outer non-neural ectoderm layers of the infected aggregates were mechanically isolated to maintain an epithelial cell population and were cultured with FGF7 and FGF10 (Fig. 2d).
However, such techniques yield a heterogeneous cell population both between and within aggregates, which results in a limited developmental potential and a low production yield.
