Area of Science:

  • Oncology
  • Cell Biology
  • Biotechnology

Background:

  • Tumor cell invasion is crucial for metastasis.
  • Understanding invasion mechanisms requires reliable experimental models.
  • In vitro assays mimic in vivo tumor cell behavior.

Purpose of the Study:

  • To describe the methodology of the Matrigel in vitro invasion assay.
  • To validate the assay's predictive power for in vivo tumor invasion.
  • To elucidate mechanisms of tumor cell invasion.

Main Methods:

  • Utilizes a modified Boyden chamber assay.
  • Employs Matrigel as a basement membrane matrix barrier.
  • Uses NIH-3T3 conditioned media as a chemoattractant.

Main Results:

  • The assay demonstrates a strong correlation between in vitro invasion and in vivo behavior.
  • This validates the Matrigel assay as a measure of metastatic potential.
  • Provides a reproducible method for assessing tumor cell invasiveness.

Conclusions:

  • The Matrigel invasion assay is a valuable tool for studying tumor cell invasion.
  • The assay accurately predicts the invasive potential of tumor cells.
  • This method facilitates research into the mechanisms of cancer metastasis.
