(H) Secreted IL-8 in SATMVEC conditioned medium standardized to total protein concentration quantified using Luminex (n = 16, 16). Data are presented as mean ± SEM, with individual data points representing biological replicates, unless otherwise indicated. Violin plots show the distribution of individual values. P values for comparisons between the heart failure (HF) and HF with type 2 diabetes mellitus (HFDM) groups were calculated using Student’s t -test or the Mann-Whitney U test as appropriate according to data distribution. ∗ P < 0.05, ∗∗ P < 0.01, and ∗∗∗ P < 0.001. AU = arbitrary units; HPF = high power field; OCR = oxygen consumption rate; TPM = transcripts per million.

Article Title: Subventricular Zone‐on‐a‐Chip: A Model to Study Neurogenesis Disruption in Neonatal Intraventricular Hemorrhage

doi: 10.1002/advs.202502145

Figure Lengend Snippet: Overview of the SVZ‐on‐a‐chip. A) The SVZ‐on‐a‐chip structure 24 h post‐seeding, showing distinct cellular compartments visualized via staining. The entire chip structure is shown (scale bar = 3000 µm) alongside a magnified maximum Z‐projection view (scale bar = 100 µm). Arrows indicate neural stem cells (NSCs), and triangles highlight human fetal astrocytes (HFAs) embedded in Matrigel, occupying the central channel. The right channel is lined with human brain microvascular endothelial cells (HBMECs), while the left channel contains human choroid plexus epithelial cells (HCPEpiC). B) Neural channel with HCPEpiC seeded along the central channel (scale bar = 200 µm). C) The central channel, highlighted by triangles, is shown in closer detail (scale bar = 200 µm). D) 3D view of the inner channel, showing cells stained with Nestin (gray). Astrocytes, marked by triangles, are stained red but lack Nestin expression (scale bar = 70 µm). E) Inner channel viewed from a different angle (scale bar = 70 µm). F) Vascular channel lined with HBMECs (scale bar = 70 µm). G) HBMECs fully covering the vascular channel (scale bar = 70 µm). H) A magnified maximum Z‐projection view of the SVZ‐on‐a‐chip 7 days after complete seeding, showing significant cellular growth (scale bar = 100 µm). Clusters of NSCs are observed invading both the neural and, predominantly, the vascular channel. I) Maximum Z‐projection view of Nestin staining in the middle channel (scale bar = 100 µm). J) Close‐up of DCX‐positive neural stem cells invading the vascular channel. DCX staining was used instead of Nestin because HBMECs also express Nestin (scale bar = 50 µm). SVZ: Subventricular Zone, NSCs: Neural Stem Cells, HFAs: Human Fetal Astrocytes, HBMECs: Human Brain Microvascular Endothelial Cells, HCPEpiC: Human Choroid Plexus Epithelial Cells, DCX: Doublecortin.
