As one bee expert writes, sweat bees are "morphologically monotonous" — which is a way of saying they all look a lot alike.
In addition, alkaline phosphatase (AP) staining shows that after 72 h of incubation, mES cells treated with 1 (at 100, 200, and 500 μM) maintain a relatively high rate of growth of colonies without losing the high activity of AP (i.e., the ratio of AP-positive colonies is nearly 100%, Figures 2B and S12) and are morphologically normal, which is identical to control cells.
Reclassifications encounter problems because the Myxogastriae are morphologically very plastic, which is to say susceptible to environmental influences; only a few characteristics are diagnostic for a small number of species.
The only morphologically divergent specimen, which is larger and darker and originates from Tasmania ("DNA M. Balke 2099"), is nested in a clade comprising specimens from New South Wales and Victoria.
Landscape B is from the Želiv area of the Bohemian Moravian Highlands, which is morphologically not very distinctive.
The term apoptosis or programmed cell death defines a genetically encoded cell death program, which is morphologically and biochemically distinct from necrosis or accidental cell death.
In this study, we identified an Arabidopsis mutant, hps10 (hypersensitive to Pi starvation 10), which is morphologically normal under Pi sufficient condition but shows increased inhibition of primary root growth and enhanced production of lateral roots under Pi deficiency.
After a certain number of cell divisions, MSC enter senescence, which is morphologically characterized by enlarged and irregular cell shapes and ultimately a stop of proliferation.
At these passages, cells displayed a cobblestone appearance, which is morphologically normal for endothelial cells.
This subpopulation was named T3A, which is morphologically different from the endothelial cells when they are adherent growth.
