System for Patterning Polydopamine and VAPG Peptide on Polytetrafluoroethylene and Biodegradable Polyesters for Patterned Growth of Smooth Muscle Cells In Vitro. ACS OMEGA 2023; 8:22055-22066. [PMID: 37360448 PMCID: PMC10285958 DOI: 10.1021/acsomega.3c02114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 05/26/2023] [Indexed: 06/28/2023]
Abstract
Biomaterial's surface functionalization for selective adhesion and patterned cell growth remains essential in developing novel implantable medical devices for regenerative medicine applications. We built and applied a 3D-printed microfluidic device to fabricate polydopamine (PDA) patterns on the surface of polytetrafluoroethylene (PTFE), poly(l-lactic acid-co-D,l-lactic acid) (PLA), and poly(lactic acid-co-glycolic acid) (PLGA). Then, we covalently attached the Val-Ala-Pro-Gly (VAPG) peptide to the created PDA pattern to promote the adhesion of the smooth muscle cells (SMCs). We proved that the fabrication of PDA patterns allows for the selective adhesion of mouse fibroblast and human SMCs to PDA-patterned surfaces after only 30 min of in vitro cultivation. After 7 days of SMC culture, we observed the proliferation of cells only along the patterns on PTFE but over the entire surface of the PLA and PLGA, regardless of patterning. This means that the presented approach is beneficial for application to materials resistant to cell adhesion and proliferation. The additional attachment of the VAPG peptide to the PDA patterns did not bring measurable benefits due to the high increase in adhesion and patterned cell proliferation by PDA itself.

Abstract
During patterning of the peripheral nervous system, motor axons grow sequentially out of the neural tube in a segmented fashion to ensure functional integration of the motor roots between the surrounding cartilage and bones of the developing vertebrae. This segmented outgrowth is regulated by the intrinsic properties of each segment (somite) adjacent to the neural tube, and in particular by chemical repulsive guidance cues expressed in the posterior half. Yet, knockout models for such repulsive cues still display initial segmentation of outgrowing motor axons, suggesting the existence of additional, yet unknown regulatory mechanisms of axon growth segmentation. As neuronal growth is not only regulated by chemical but also by mechanical signals, we here characterized the mechanical environment of outgrowing motor axons. Using atomic force microscopy-based indentation measurements on chick embryo somite strips, we identified stiffness gradients in each segment, which precedes motor axon growth. Axon growth was restricted to the anterior, softer tissue, which showed lower cell body densities than the repulsive stiffer posterior parts at later stages. As tissue stiffness is known to regulate axon growth during development, our results suggest that motor axons also respond to periodic stiffness gradients imposed by the intrinsic mechanical properties of somites.

Abstract
Vertebrate segmentation, the process that generates a regular arrangement of somites and thereby establishes the pattern of the adult body and of the musculoskeletal and peripheral nervous systems, was noticed many centuries ago. In the last few decades, there has been renewed interest in the process and especially in the molecular mechanisms that might account for its regularity and other spatial-temporal properties. Several models have been proposed but surprisingly, most of these do not provide clear links between the molecular mechanisms and the cell behaviours that generate the segmental pattern. Here we present a short survey of our current knowledge about the cellular aspects of vertebrate segmentation and the similarities and differences between different vertebrate groups in how they achieve their metameric pattern. Taking these variations into account should help to assess each of the models more appropriately.

Abstract
Contact repulsion of growing axons is an essential mechanism for spinal nerve patterning. In birds and mammals the embryonic somites generate a linear series of impenetrable barriers, forcing axon growth cones to traverse one half of each somite as they extend towards their body targets. This study shows that protein disulphide isomerase provides a key component of these barriers, mediating contact repulsion at the cell surface in chick half-somites. Repulsion is reduced both in vivo and in vitro by a range of methods that inhibit enzyme activity. The activity is critical in initiating a nitric oxide/S-nitrosylation-dependent signal transduction pathway that regulates the growth cone cytoskeleton. Rat forebrain grey matter extracts contain a similar activity, and the enzyme is expressed at the surface of cultured human astrocytic cells and rat cortical astrocytes. We suggest this system is co-opted in the brain to counteract and regulate aberrant nerve terminal growth.
