Abstract

Insights

Surgical orthotopic implantation (SOI) mouse models accurately mimic human clinical cancer, including metastasis and drug response. These imageable models are crucial for effective cancer drug discovery and evaluation.

Area of Science:

  • Oncology
  • Translational Research
  • Preclinical Cancer Models

Background:

  • Current rodent models inadequately represent human cancer, particularly metastasis and drug sensitivity.
  • Transgenic and subcutaneous xenograft models show limitations in clinical accuracy.
  • There is a critical need for more relevant preclinical cancer models.

Purpose of the Study:

  • To introduce and review the surgical orthotopic implantation (SOI) technique for creating clinically relevant cancer models.
  • To highlight the utility of SOI models for drug discovery and evaluation.
  • To discuss the application of imageable models for in vivo cancer research.

Main Methods:

  • Surgical orthotopic implantation (SOI) of histologically intact human tumor fragments into corresponding organs of immunodeficient rodents.
  • Utilization of human tumor cell lines and patient-derived tumors within SOI models.
  • Incorporation of fluorescent proteins for non-invasive in vivo visualization of tumor growth and metastasis.

Main Results:

  • SOI models enable the expression of tumor growth and metastatic potential, mirroring clinical cancer.
  • These models facilitate the discovery and evaluation of effective anti-cancer drugs.
  • Imageable SOI models allow for non-invasive monitoring of cancer initiation, progression, and response to therapy.

Conclusions:

  • Surgical orthotopic implantation (SOI) mouse models effectively reproduce key features of clinical human cancer.
  • SOI models offer a powerful platform for advancing cancer research and therapeutic development.
  • These models are essential for improving the accuracy of preclinical drug testing.
