Sentence examples for conglomerate of cells from inspiring English sources

After many rounds of cleavage, this spherical conglomerate of cells (now called a blastula) begins to exhibit some specification of germ layers (endoderm, mesoderm, and ectoderm) and then proceeds to invaginate at one end, a complex process referred to as gastrulation that eventually yields a through-gut.

Indeed, it was so pervasive, Dr. Woese suggested recently, that the universal ancestor was probably not a single-celled organism but a commune -- a loosely knit conglomerate of diverse cells that exchanged genetic information.

However, multicellular organisms are more than a conglomerate of undifferentiated cell types, and specialization of cell types is a defining feature of multicellular organisms.

Figure 3 shows an example in which a conglomerate of BRC cells colocalizes with a few promonocytes.

For the cellulases and related enzymes (the glycoside hydrolases) collectively comprise unique enzyme systems that decompose a unique type of substrate: the intricate conglomerate of plant cell wall polysaccharides.

In PBS supplemented with glycolysis substrates (5.56 mM glucose, 25 mM lactate and 0.5 mM pyruvate), spermatozoa from heterozygous males exhibited slow tail movement and adhered to one another by way of their heads, forming large, slowly moving conglomerates and trains of cells; the proportion of free-swimming cells was negligible (Supplemental Video S1).

At the next evolutionary stage the conglomerates of neuronal cell bodies, the ganglia, appeared, thus forming the primitive centralized nervous system.

In aggregate, the growing tumour mass consists of conglomerates of independent cell clusters developing in the vicinity of each other – the product of a continual 'self-metastasis' process that has recently been proposed to drive tumour growth (Norton, 2005; Norton and Massague, 2006).

While isolated cells (28 to 80 µm2) are counted directly, the number of cells contained in a conglomerate is estimated by dividing the area of the conglomerate in thin tissues sections (≤6 µm) by the median area covered by an isolated T cell which we determined as 58 µm2.

This is especially the case with the difficult estimation of the number of cells contained in complex cell conglomerates (see figure 1), leading to incomplete evaluations of slides [15].

Moreover, deletion of rac1 for an extended period of time (i.e., 15 months) results in the appearance of large areas (conglomerates) of MPO-positive cells.
