What process might give rise to this population of cells?
Transcribed Image Text:The image shows a microscopic view of cells stained for examination. The pink and purple hues represent different cellular components, typically dyed to differentiate between cell structures.
**Description:**
- **Cell Types**: The image illustrates a number of rounded cells, characteristic of hematopoietic or blood-related cells. Each cell contains a central nucleus stained with a darker purple, indicating the DNA-rich center. Surrounding the nucleus, lighter shades suggest cytoplasmic regions.
- **Staining Technique**: The uniformity and color differentiation are likely achieved through a common staining method such as Wright-Giemsa or hematoxylin and eosin (H&E), which is used to highlight cellular components for better contrast under a microscope.
- **Cell Arrangement**: The cells appear clustered in groups, which could be indicative of either a sample from a bone marrow smear or a cytology specimen.
This visualization aids in the study of cellular morphology and can assist in diagnosing various blood disorders or infections by identifying abnormal cells or inclusions.

Step 1
White blood cells (WBC) are a variety of nucleated cells that circulate for at least a portion of their lifespan. Between 4000 and 10,000 microliters are often found of them in blood during normal conditions. They are very crucial for phagocytosis, immunity, and consequently infection defence.
