VEGF-A and FGF-2 are two angiogenic growth factors involved in the growth and invasion of solid tumours and haematological malignancies. They are also believed to play an important role in cardiovascular and inflammatory diseases. Several studies dealing with measurement of circulating FGF-2 and VEGF have been published during the last decade. We have studied the levels of FGF-2 and VEGF-A in serum and EDTA plasma from 80 healthy blood donors. The samples were analyzed using the most widely used and commercially available ELISAkits. There was no significant effect of age on any of the assays and no effect of sex on P-FGF-2, S-VEGF-A and P-VEGF-A. Using the 97.5th percentile we obtained the following reference values: P-FGF-2 < 6.4 ng/l; S-VEGF-A < 500 ng/l; P-VEGF-A < 80 ng/l. Separate gender based reference intervals were made for S-FGF-2 as women had significantly higher S-FGF-2 values. Reference values for S-FGF-2 were <4.0 ng/l (men) and <10.8 ng/l (women).

Traditional cell culture methods face significant limitations in monitoring cell secretions with spatial and temporal precision. Advanced microsystems incorporating biosensors have been developed to address these challenges, but they tend to lack versatility, and their complexity, along with the requirement for specialized equipment, limits their broader adoption. CellStudio offers an innovative, user-friendly solution that exploits Printing and Vacuum Lithography combined with bead-based assays to create modular and tunable cell patterns surrounded by biosensors.

Wound healing is a highly coordinated process driven by intricate molecular signaling and dynamic interactions between diverse cell types. Nod-like receptor pyrin domain-containing protein 3 (NLRP3) has been implicated in the regulation of inflammation and tissue repair; however, its specific role in skin wound healing remains unclear. This study highlights the pivotal role of NLRP3 in effective skin wound healing, as demonstrated by delayed wound closure and altered cellular and molecular responses in NLRP3-deficient (NLRP3) mice.

Purpose: Ocular neovascularization is a major cause of blindness. Although fibroblast growth factor-2 (FGF2) has been implicated in the pathophysiology of angiogenesis, the underlying mechanisms remain incompletely understood. The purpose of this study was to investigate the role of FGF2 in retinal neovascularization and elucidate its underlying mechanisms.

Angiopoietin-1 (Ang-1) and its receptor Tie-2 promote vascular integrity and angiogenesis. MicroRNAs (miRNAs) are involved in the regulation of many cellular functions, including endothelial cell (EC) survival, proliferation, and differentiation. Several reports indicate that these effects of miRNAs on EC functions are mediated through the modulation of angiogenesis factor signaling including that of vascular endothelial growth factor (VEGF).

Article Synopsis
- Traumatic brain injury (TBI) affects many individuals, especially veterans and athletes, and has serious, long-term consequences for brain health.
- Current research explores the role of fibroblast growth factor (FGF) proteins in protecting cells, highlighting knowledge gaps regarding how heparin and similar molecules activate bFGF and how mutations affect its stability.
- Using temperature replica exchange, the study identified a new binding site on bFGF and revealed that various sugars affect bFGF interactions similarly to heparin, underscoring the need for a deeper understanding of TBI mechanisms for better treatment development.
