Abstract
The glomerular filtration barrier (GFB), composed of glomerular endothelial cells (GEnCs), the glomerular basement membrane (GBM), and podocytes, serves as a highly selective interface regulating fluid and solute exchange between blood and urine. This review synthesizes current understanding of the anatomy, developmental biology, and molecular signaling pathways that govern the structure and function of each GFB component. Key regulators such as vascular endothelial growth factor (VEGF), nephrin, integrins, and laminins are discussed in the context of barrier formation, maintenance, and injury response. Advanced imaging methods including electron microscopy, intravital microscopy, and super-resolution techniques are reviewed for their roles in characterizing nanoscale GFB architecture. To bridge glomerular biology with engineering applications, we critically evaluate how these insights inform the design of bioinspired hemodialysis (HD) membranes. Strategies such as endothelialization, extracellular matrix (ECM) coatings, and triculture systems are explored, alongside recent developments in glomerular-inspired membranes and organ-on-chip models. We also address the practical challenges of translating these biological features into scalable, hemocompatible dialysis technologies. By integrating advances in cell biology, materials science, and microfluidic modeling, this review provides a framework for the development of next-generation dialysis membranes that more closely replicate native kidney filtration.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
