Human Melanoma Skin Cancer Models: A Step Towards Drug Testing & Target Therapy

Area of Science:

• Oncology
• Biotechnology
• Drug Discovery

Background:

• Melanoma, an aggressive skin cancer, exhibits complex heterogeneity impacting treatment response.
• Traditional 2D cell cultures and rodent models inadequately mimic the human tumor microenvironment.
• Developing advanced ex vivo models is crucial for understanding melanoma progression and predicting treatment outcomes.

Purpose of the Study:

• To comprehensively review three-dimensional (3D) models for melanoma drug screening.
• To critically evaluate the accuracy and therapeutic efficacy of these 3D models in targeted therapy.
• To identify challenges and propose future directions for 3D model-based drug screening.

Main Methods:

• Systematic screening of 120 studies related to 3D melanoma models.
• Critical discussion of 22 key research publications.
• Analysis of drug screening accuracy and therapeutic efficacy data from selected studies.

Main Results:

• 3D models, including spheroids, organoids, bio-printed constructs, and microfluidic devices, show promise in mimicking melanoma's in vivo environment.
• These models demonstrate improved accuracy in predicting drug efficacy compared to 2D cultures.
• Key research highlights the potential of 3D models for evaluating targeted therapies.

Conclusions:

• 3D melanoma models represent a significant advancement over traditional methods for drug discovery and development.
• Further refinement of these models is necessary to overcome current challenges and enhance their predictive power.
• Enhanced 3D model-based drug screening can accelerate the development of effective targeted therapies for melanoma.
