- Collagen I induces microvascular endothelial cells to adopt a spindle-shaped morphology, in vitro, and to align into solid cord-like assemblies. Vascular endothelial cells can also form vessel-like, tubular structures when cultured on collagen I. Collagen I can be used for in vitro angiogenesis assays.
- Breast cancer stem cells can undergo differentiation when cultured on collagen I.
- Collagen I has been used for the culture of primary colon carcinoma cell lines; mouse liver progenitor cells have been cultured in 3D collagen I and rat pancreatic islets.
- Collagen I can act as a barrier in cell invasion assays, and has been used to study cell adhesion.
What are some general differences between Gibco Geltrex Matrix, collagen, AlgiMatrix 3D Culture System, and CTS Cellstart Substrate?
Gibco Geltrex Matrix and collagen (rat tail and bovine) can be used as either a coating solution or a 3D gel matrix. CELLstart Substrate was developed to be used as a xeno-free coating matrix for only ESC applications (as a substitute for Gibco Geltrex Matrix or Matrigel Matrix, which are of animal origin). AlgiMatrix Matrix is a 3D scaffold-type matrix that does not support cell attachment but does provide a good environment for growing spheroids that can be easily harvested for downstream applications.
