Synthetic Surrogates of Collagen-Rich Microenvironments with Tunable Viscoelasticity

Rafael A. Castro published a dataset on figshare in May 2026 describing synthetic collagen mimetic peptides (mfCMPs) and their integration into hydrogel-based synthetic extracellular matrices. The dataset includes methods for imaging nano- and micro-structures using super-resolution microscopy and data on the resulting tunable viscoelastic properties. The 184.3 MB ZIP file contains data supporting the creation of fully synthetic surrogates for collagen-rich tissues.

Use Cases

• Designing synthetic extracellular matrices based on modular bioactive fibrillar structures described in the dataset.
• Studying cell behavior, such as breast cancer spheroid formation, in tunable viscoelastic environments.
• Developing imaging protocols for nano- and micro-structures within hydrogels using super-resolution microscopy.
• Parsing the roles of collagen-like hierarchical structure, viscoelasticity, and bioactivity in tissue mimics.

Strengths

• Dataset includes super-resolution microscopy images of nano- and micro-structures within hydrogels.
• Data supports the creation of hydrogels with tunable, concentration-dependent viscoelasticity exhibiting relaxation half times over orders of magnitude.
• The synthetic ECMs were shown to support the formation of large, growing breast cancer cell spheroids.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect the specific experimental bias inherent to the author's research platform.
