Practical murine hematopathology: a comparative review and implications for research

Area of Science:

• Comparative hematology
• Translational biomedical research
• Murine models in disease

Background:

• Hematologic parameters are vital disease indicators in human and veterinary medicine.
• Mouse models are essential for studying disease mechanisms and therapies applicable across species.
• Significant hematologic distinctions exist between mice and humans, impacting research accuracy.

Purpose of the Study:

• To review the unique aspects of murine hematology and hematopathology.
• To provide practical insights for translational investigations using mouse models.
• To emphasize the importance of understanding murine hematologic differences for accurate research.

Main Methods:

• Review of existing literature on murine hematology and hematopathology.
• Comparison of murine hematologic parameters with those of humans and other species.
• Identification of key differences relevant to disease modeling and therapeutic research.

Main Results:

• Mice exhibit smaller erythrocytes, higher reticulocyte counts, and different leukocyte profiles compared to humans.
• Physiologic splenic hematopoiesis and distinct iron storage mechanisms are characteristic of mice.
• Murine erythrocytes and platelets are more numerous and have shorter lifespans.

Conclusions:

• Accurate hematologic analysis in translational research requires understanding murine-specific features.
• Knowledge of murine hematopathology is essential for interpreting disease models and therapeutic responses.
• This review facilitates the effective use of mouse models in advancing biomedical science.
