Summary: Lymphatic dysfunction is associated with the progression of several vascular disorders, and there are limited strategies currently available to promote new lymphatic vasculature. This study isolated lymphatic endothelial progenitor cells from human umbilical cord blood and found that they have the potential to promote lymphatic sprouts, highlighting the therapeutic potential of these cells. Delivery of lymphatic EPCs using alginate hydrogels also showed promise for possible therapeutic applications.

Summary: A potential heparan sulfate (HS) ligand was discovered to target several growth factors using specific HS tetrasaccharide ligands. One tetrasaccharide ligand showed strong binding with the VEGF(165) growth factor, and in vitro experiments demonstrated the therapeutic potential of these synthetic HS ligands by inhibiting vascular endothelial cell proliferation, migration, and angiogenesis in the presence of VEGF(165) and the specific tetrasaccharides.

Summary: The study introduced a GelMA microneedle platform for sustained and controlled local delivery of AAV-VEGF, which achieved homogeneous distribution and high transfection efficiency in ischemic brains. Results showed that MNs loaded with AAV-VEGF increased VEGF expression in the brain cortex and enhanced functional angiogenesis and neurogenesis.

Summary: Circulating VEGF levels were found to be elevated 24-48 hours after acute ischemic stroke and were associated with prognosis of moderate to severe disability at 6 months. Combining VEGF with interleukin 6 and C-reactive protein significantly improved predictive performance compared to using VEGF alone.

Summary: Angiogenesis plays a crucial role in embryologic development, growth, and tissue repair, but dysregulation of this process is a hallmark of various pathologies, including cancer. Existing methods for evaluating cell vascular formation are often limited to static analysis, leading to bias. Researchers have developed code scripts to study the dynamic angiogenesis process, allowing for the screening of drugs that can affect various parameters of vascular formation. Animal experiments have confirmed the efficacy of these drugs in inhibiting blood vessel formation, providing a new perspective for angiogenesis research and drug development.

Summary: This study presents a simulation mimicking tumor angiogenesis microenvironment on-chip, aiming to establish favorable conditions for gradients of vascular endothelial growth factor. The model platform explores different responses of endothelial cells in a micro-confined fluidic environment, showing potential significance for organ-on-a-chip assays, disease modeling, and optimizing anti-angiogenic therapies.

Summary: There are currently no effective treatments for liver fibrosis, a disease that involves angiogenesis. The role of different microvessels in the liver during fibrogenesis is unclear, and it is difficult to treat liver fibrosis through vascular targeting. This study proposes a combined regulation of multiple different endothelial cell regulatory signaling pathways as a new strategy for liver fibrosis therapy.

Summary: This study demonstrated that MWCNTs can affect endothelial cell activity, disrupt tube formation and cell migration ability, subsequently affecting angiogenesis. Furthermore, the VEGF-Akt-eNOS axis plays a crucial role in MWCNT-induced endothelial cell injury.

Summary: The study investigated the role of vascular endothelial growth factor (VEGF) in ischemic and non-ischemic skeletal muscle in patients with peripheral arterial disease (PAD). The results showed that preoperative VEGF levels were significantly higher in ischemic muscles compared to controls, and postoperative values decreased significantly. There was no significant change in VEGF levels in the non-ischemic muscle. This suggests impaired angiogenesis mechanisms in PAD patients.

Summary: This study investigated the role of integrins in promoting adhesion, growth, development, and vascular-like network formation of rat primary brain microvascular endothelial cells. By using an integrin-binding array platform, specific types of integrins and their binding peptides were identified. Furthermore, a 3D hydrogel culture system functionalized with these binding peptides promoted robust growth and lumenized microvascular-like network formation of brain microvascular endothelial cells.

Summary: VEGF-A(165) positively affects hyperplasia, stenosis, and neovascularization, but its short half-life limits its potential therapeutic use. To address this issue, we designed VEGF-A(165) bioconjugates carrying PEG. After purification, two PEGylated species were obtained, with one or two PEG attached per VEGF-A(165) dimer. Both bioconjugates exhibited high purity, wild-type bioactivity, and increased hydrodynamic radii.
