the number of cells in the brain are: (1) Either model-based or design-based counting of stained cells, nuclei or nucleoli or their fragments in histological sections; (2) DNA extraction and measurement of total DNA content to calculate...

and differentiated hESCs. Undifferentiated hESCs have a high ratio of nucleus to cytoplasm, prominent nucleoli, indistinct cell membranes, free ribosomes, and small mitochondria with a few crista, whereas differentiated cells retain...

to die. 2. The nucleus is surrounded by the nuclear envelope, a double membrane penetrated by fairly large pores. 3. Nucleoli are nuclear sites of ribosome subunit synthesis. 4. Chromatin is a complex network of slender threads...

abundant pale blue cytoplasm. The chromatin is coarsely reticulated and the cells often have small multiple nucleoli. Cells display moderate anisocytosis and anisokaryosis. These are noted individually and in loose aggregates. In the...

발생한다. 3.Cytologic features: - Large and bizarre nuclei with eccentric location. - Prominent and eosinophilic nucleoli. - Big rhabdoid cells with a pink cytoplasmic blob. - Large variation in cell size. - A medulloblastoma like...

line (SCNT-hES-1) was derived. The resulting SCNT-hES-1 cells had a high nucleus-to-cytoplasm ratio and prominent nucleoli. The cell colonies displayed similar morphology to that reported previously for hES cells derived after IVF (Fig...

pleomorphism. Typical characteristics have included anisocytosis, anisokaryosis, vesicular nuclei with prominent nucleoli, degree of cytoplasmic granulation, and mitotic activity (Figs. 8A & C). More recently, AgNOR staining and scores...

에서 분화함. Fibroblasts have a branched cytoplasm surrounding an elliptical, speckled nucleus having two or more nucleoli. Active fibroblasts can be recognized by their abundant rough endoplasmic reticulum. Inactive fibroblasts, which...
