Classification of Leukocytes

Classification of Leukocytes

Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Structure and Function of Leukocytes

Structure and Function of Leukocytes

An adult in good health typically has between 4,500 and 11,000 leukocytes, or white blood cells, per microliter of blood, which constitutes about 1% of the total blood volume. Unlike red blood cells, white blood cells contain a nucleus and other cellular organelles but do not have hemoglobin. Most white blood cells reside in connective tissues, particularly in lymphatic organs such as the lymph nodes, with only a small fraction present in circulating blood.
White blood cells protect the body...

Differentiation of Common Myeloid Progenitor Cells

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Background:

Accurate segmentation of leukocytes and their components is crucial for diagnosing diseases.
Microscopic bone marrow leukemia cell images present challenges due to heterogeneous staining and high cell density.

Purpose of the Study:

To develop a novel method for segmenting leukocytes, including their nucleus and cytoplasm, from leukemia cell images.
To leverage color and texture information for improved segmentation accuracy in complex cellular environments.

Main Methods:

Utilized the CIEL*a*b* color space for color feature extraction.
Applied a 2D Wold Decomposition model for structural and stochastic texture feature extraction.
Integrated color and texture information into an unsupervised binary Markov Random Field (MRF) segmentation model.

Main Results:

The proposed method effectively segments cellular elements from images with heterogeneous staining and high cell populations.
Experimental results demonstrated strong performance on both synthetic and real leukemia cell images.
Achieved an average accuracy of 95% in segmenting real cell images when compared to manual segmentation.

Conclusions:

The novel segmentation method shows high accuracy and effectiveness for analyzing leukemia cell images.
The integration of color and texture features within an MRF framework provides a robust approach for cellular segmentation.
This technique has significant potential for improving the diagnostic capabilities in leukemia research and clinical practice.
