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...

Cryo-electron Microscopy

Cryo-electron Microscopy

Conventional electron microscopy (EM) involves dehydration, fixation, and staining of biological samples, which distorts the native state of biological molecules and results in several artifacts. Also, the high-energy electron beam damages the sample and makes it difficult to obtain high-resolution images. These issues can be addressed using cryo-EM, which uses frozen samples and gentler electron beams. The technique was developed by Jacques Dubochet, Joachim Frank, and Richard Henderson, for...

Area of Science:

Biomedical science
Cell biology
Cryobiology

Context:

Intensive metabolism in nuclear blood cells rapidly depletes energy at positive temperatures, limiting their viable storage.
Clinical transfusion requires effective methods for preserving blood cells, particularly leukocytes.
Current ultralow temperature preservation (-196°C) necessitates liquid nitrogen, specialized equipment, and trained personnel, restricting widespread application.

Purpose:

To develop an effective and simple method for preserving leukocytes at temperatures near zero (+2°C to 0°C).
To overcome the limitations of traditional cryopreservation techniques for clinical applications.

Summary:

This study introduces a new cryopreservation solution for preserving leukocytes.
The method utilizes a standard household refrigerator for storage at near-zero temperatures.
This approach offers a simpler alternative to ultralow temperature preservation.

Impact:

Enables extended viability of leukocytes for clinical use without complex infrastructure.
Provides a more accessible and cost-effective method for blood cell preservation.
Facilitates wider clinical application of leukocyte preservation techniques.
