The iMAP platform quantifies vascular networks in microphysiological systems (MPS). It reveals differences in network stability and organization, crucial for developing better disease models.

Area of Science:

  • Biomedical Engineering
  • Vascular Biology
  • Microfluidics

Background:

  • Characterizing vascular heterogeneity in microphysiological systems (MPS), especially patient-derived tumor microenvironments, is challenging for disease modeling.
  • Current methods often focus on vessel abundance, neglecting network connectivity and spatial remodeling.

Purpose of the Study:

  • To introduce the iMAP platform for high-throughput, topology-resolved vascular profiling in MPS.
  • To enable detailed quantification of vascular architecture, including morphology, branching, connectivity, and spatial variation.

Main Methods:

  • Integration of an injection-molded microfluidic chip with an interactive image analysis tool (iMAP Analyzer).
  • Application to 3D co-cultures of patient-derived gastric cancer spheroids with iPSC-derived endothelial cells (iPSC-ECs) or HUVECs.

Main Results:

  • iMAP identified distinct network organization and spatial stability differences between iPSC-EC and HUVEC networks.
  • iPSC-derived networks showed increased fragmentation and peripheral instability.
  • Connectivity-normalized and region-resolved analysis provided deeper insights than conventional metrics.

Conclusions:

  • The iMAP framework offers a scalable, standardized method for quantitative vascular phenotyping in complex MPS.
  • This approach supports high-content analysis and advances vascularized in vitro disease model development.
