To review the integration of multiple biophysical stimuli in vascular endothelial cells (ECs) and present a framework for understanding this integration, highlighting its significance for vascular health.
Approach:
Key Findings:
ECs are constantly subjected to a complex combination of biophysical stimuli including fluid shear stress, pressure, stretch forces, and substrate topography, which are crucial for maintaining vascular health.
Most studies have focused on single stimuli, with limited research on the integration of multiple stimuli, highlighting a gap in understanding their combined effects.
The mechanical environment of ECs varies significantly in space and time, influenced by factors such as anatomical location and cardiac cycle, which complicates the interpretation of their responses.
Interpretation:
Understanding how ECs integrate multiple biophysical cues is essential for elucidating their role in vascular health and disease, particularly in conditions like atherosclerosis.
Limitations:
Challenges in accurately measuring biophysical stimuli in vivo, which can lead to misinterpretation of EC responses.
Difficulty in separating the effects of multiple coupled stimuli on EC responses, complicating the understanding of their mechanobiology.
Variability in mechanical properties of tissues upon excision complicates biophysical measurements, affecting the reliability of in vitro studies.
Conclusion:
A comprehensive understanding of EC mechanobiology requires further investigation into how these cells integrate diverse biophysical stimuli, with a focus on future research directions.
A prespecified exploratory analysis of the FIND-CKD clinical trial examined kidney function, albuminuria, and kidney failure outcomes in 903 patients with glomerular diseases.
