3D-Embedded Cell Cultures to Study Tendon Biology.

Tendons harbor various cell populations, including cells displaying classical adult mesenchymal stromal cell criteria. Previous studies have shown that a tenogenic phenotype is more effectively maintained in a 3D cell culture model under mechanical load. This chapter describes a method to isolate tendon-derived cells from rat Achilles tendons and the subsequent formation of 3D-embedded cell cultures. These tendon-like constructs can then be analyzed by various means, including histology, immunohistochemistry, qPCR, or standard protein analysis techniques.
