Sentences with phrase «detect populations of cells»

Instead, the team used functional magnetic resonance imaging (fMRI) to detect populations of cells that seemed to fire as the volunteers played a virtual reality game in which they had to replace an object in the location where they originally found it.

Not exact matches

They have detected, for example, revved up signaling molecules involved in inflammation, such as tumor necrosis factor α (TNFα) and other cytokines; skewed populations of natural killer cells and other immune cells; imbalances in the protein - destroying enzymes called proteases; and a shortening of the telomeres, the «end caps» on chromosomes, which indicates prematurely aged cells.

Targeting the labeled cells for analysis, they revealed that their organoids contained a population of sensory cells that have the same functional signature as cells that detect gravity and motion in the human inner ear.

In this instance we did not detect a plating difference in the populations and approximately 16 % of the deposited cells survived to give rise to day 10 cultures (unpublished data).

These cells were detected in the peripheral region of the EBs as specific cell populations, such as SSEA1 - positive, OCT -4-positive cells, OCT -4-positive, VASA - positive cells, and OCT -4-negative, VASA - positive cells.

A robust CD45 + cell population was detected (A) of which a large portion was Gr - 1 + (B).

Interestingly, when we looked at the splenocytes in these mice and compared them to controls, we were not able to detect a significant difference in the numbers of Tregs, suggesting that in the transplant model, Tregs may be within the graft - infiltrating population where they could regulate infiltrating host T cells.

Although we were able to now detect more distinct T and B cell populations in the transplanted immunocompetent MRL and 129SvJ mice, the numbers of lymphoid cells remained far less than would be expected after bone marrow transplantation.

Bioelectrical impedance vector analysis (BIVA) expresses tissue hydration status and body cell mass solely while considering the impedance vector relative to a population of healthy individuals (24); this was a valid method for detecting changes in hydration (classified as under -, normal or overhydration) and body fluid volume changes (25).
