Purpose of the Study:

• To establish a roadmap for systematic drug discovery screening using zebrafish xenograft cancer models.
• To analyze critical factors impacting the successful implementation of these models.
• To provide guidelines for optimizing zebrafish models in cancer research.

Main Methods:

• Exploration of user-independent inclusion criteria and sample homogeneity.
• Definition of metrics for data analysis and tumor engraftment criteria.
• Comparison of image analysis with qPCR for cell quantification, and evaluation of implantation sites and compound administration methods.

Main Results:

• Identification of crucial factors for successful zebrafish xenograft model implementation.
• Development of a systematic roadmap for drug discovery screening.
• Demonstration of the model's utility using a melanoma cell line.

Conclusions:

• Zebrafish xenograft models provide a versatile and cost-effective platform for in vivo cancer drug screening.
• The proposed roadmap facilitates systematic screening and adoption by the research community.
• Standardized guidelines are essential for maximizing the potential of zebrafish models in drug discovery.
