Key result
A heterogeneous computational model of microvascular networks demonstrated a >70% reduction in volume flow rate and a ~120% increase in protein movement into tissues relative to a homogeneous model.
Why the study?
Integrating functional microvascular exchange data across scales requires mathematical modelling, but how network architecture and heterogeneity affect fluid and protein transport remained unclear under standard simplified assumptions.

Modeling heterogeneity in microvascular networks reveals that network architecture significantly reduces capillary hydrostatic pressures and volume flow rate while increasing protein movement into tissues.
Guidoboni et al. (2021) studied this question. Heterogeneous Scenario (realistic microvascular network components) vs. Homogeneous Scenario and Class Uniform Scenario was evaluated on Volume flow rate and protein movement. A heterogeneous computational model of microvascular networks demonstrated a >70% reduction in volume flow rate and a ~120% increase in protein movement into tissues relative to a homogeneous model.
