Scanning electron microscopy of myeloma cells

Area of Science:

• Hematology
• Cell Biology
• Oncology

Background:

• Multiple myeloma is a cancer of plasma cells.
• Understanding cell surface morphology is crucial for diagnosis and treatment.
• Previous studies have not extensively detailed myeloma cell surface ultrastructure.

Observation:

• Myeloma cells were isolated from patient pleural effusion.
• Conray-Ficoll gradient sedimentation was used for cell purification.
• Scanning electron microscopy (SEM) was employed to visualize cell surfaces.

Findings:

• Myeloma cells exhibited significant surface villousness.
• Observed cell diameters ranged from 8 to 12 micrometers.
• Microvilli length varied between 0.8 and 1.2 micrometers.
• Myeloma cell surfaces were markedly more villous compared to lymphocytes.

Implications:

• SEM can differentiate myeloma cells from lymphocytes based on surface features.
• Surface villousness may serve as a diagnostic or prognostic indicator.
• Further research could explore the functional role of microvilli in myeloma.
