Area of Science:

  • Oncology
  • Cancer Research
  • Dermatology

Background:

  • Melanoma is an aggressive cancer with rapid metastasis.
  • Recent treatments improve survival but secondary resistance remains a challenge.
  • Understanding resistance mechanisms is vital for effective melanoma treatment.

Purpose of the Study:

  • To provide a comprehensive overview of experimental techniques for melanoma research.
  • To discuss the strengths and weaknesses of various melanoma models.
  • To highlight the role of patient-derived models in studying treatment resistance.

Main Methods:

  • Review of current experimental techniques for melanoma modeling.
  • Analysis of 3D and 4D culture techniques.
  • Evaluation of organotypic skin reconstructs, melanoma-on-chip models, and patient-derived xenografts.

Main Results:

  • Various techniques exist for melanoma modeling, each with unique advantages and limitations.
  • Patient-derived models offer valuable insights into melanoma biology and treatment resistance.
  • The choice of technique depends on experimental goals, throughput, and desired reflection of human conditions.

Conclusions:

  • Patient-derived melanoma models are essential for dissecting treatment resistance mechanisms.
  • A range of experimental models are available, requiring careful selection based on research needs.
  • Further development and application of these models will advance melanoma treatment strategies.
