Abstract

It is well known that biophysical properties of the extracellular matrix (ECM), including stiffness, porosity, composition, and fiber alignment (anisotropy), play a crucial role in controlling cell behavior in vivo. Type I collagen (collagen I) is a ubiquitous structural component in the ECM and has become a popular hydrogel material that can be tuned to replicate the mechanical properties found in vivo. In this review article, we describe popular methods to create 2-D and 3-D collagen I hydrogels with anisotropic fiber architectures. We focus on methods that can be readily translated from engineering and materials science laboratories to the life-science community with the overall goal of helping to increase the physiological relevance of cell culture assays.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Efforts have been made to design anisotropic matrix structures in CoC devices, particularly collagen type I, to recapitulate in vivo-like aligned collagen-rich ECM interacting with invasive tumors, using engineered, directional force-derived, or cell-derived approaches.

    “More recently, however, efforts have been made to design anisotropic matrix structures (including in CoC devices) in particular, but not exclusively, collagen type I [24], with the aim of recapitulating in vivo-like aligned collagen-rich ECM interacting with invasive tumors [25] by using (i) engineered, (ii) directional force-derived, or (iii) cell-derived approaches (Figure 2A-C and Table 1).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
