Matrigelinvasionassays
OverviewMatirgel is considered as basement membrane and generated from EHS sarcoma. Matrigel contains not only basement membrane components (collagens, laminin, and proteoglycans)but also matrix degrading enzymes/their inhibitors and growth factors. Invasion of tumor cells into Matrigel has been used to characterize involvement of ECM receptors and matrix degrading enzymes which play roles in tumor progression. ......阅读全文
