A Bird's Eye View: A Close Look into Avian CAM Models for Translational Blood Cancer Research

Area of Science:

• Oncology
• Developmental Biology
• Immunology

Background:

• The chorioallantoic membrane (CAM) is an extra-embryonic membrane supporting avian development.
• CAM xenograft models are established for solid tumors, offering rapid, cost-effective, and ethical research avenues.
• Their application in hematological malignancy research is underexplored.

Purpose of the Study:

• To review the relevance, advantages, and translational potential of avian CAM models for studying blood cancers.
• To discuss applications in leukaemias, lymphomas, and myelomas.
• To evaluate species-specific considerations for model fidelity and limitations.

Main Methods:

• Literature review focusing on avian CAM models for hematologic malignancies.
• Analysis of experimental approaches replicating human disease progression and therapeutic response.
• Comparative evaluation of avian and human haematopoiesis.

Main Results:

• CAM models can be adapted to study leukaemias, lymphomas, and myelomas.
• Real-time observation of tumor growth, angiogenesis, and metastasis is possible.
• Species-specific factors influence model fidelity, presenting both opportunities and limitations.

Conclusions:

• Avian CAM models provide a valuable in vivo system for hematologic malignancy research.
• They serve as a bridge between in vitro and mammalian in vivo studies.
• Further exploration of CAM models can advance translational research in blood cancers.
