Micro and Nanofabrication methods to control cell-substrate interactions and cell behavior: A review from the tissue engineering perspective

2018-09-01
Cell-substrate interactions play a crucial role in the design of better biomaterials and integration of implants with the tissues. Adhesion is the binding process of the cells to the substrate through interactions between the surface molecules of the cell membrane and the substrate. There are several factors that affect cell adhesion including substrate surface chemistry, topography, and stiffness. These factors physically and chemically guide and influence the adhesion strength, spreading, shape and fate of the cell. Recently, technological advances enabled us to precisely engineer the geometry and chemistry of substrate surfaces enabling the control of the interaction cells with the substrate. Some of the most commonly used surface engineering methods for eliciting the desired cellular responses on biomaterials are photolithography, electron beam lithography, microcontact printing, and microfluidics. These methods allow production of nano-and micron level substrate features that can control cell adhesion, migration, differentiation, shape of the cells and the nuclei as well as measurement of the forces involved in such activities. This review aims to summarize the current techniques and associate these techniques with cellular responses in order to emphasize the effect of chemistry, dimensions, density and design of surface patterns on cell-substrate interactions. We conclude with future projections in the field of cell-substrate interactions in the hope of providing an outlook for the future studies. (c) 2018 The Authors.

Engineered natural and synthetic polymer surfaces induce nuclear deformation in osteosarcoma cells
Antmen Altunsoy, Ezgi; Ermiş Şen, Menekşe; Hasırcı, Vasıf Nejat (2019-02-01)
Cell-substrate interactions involve constant probing of microenvironment by cells. One of the responses of cells to environmental cues is to change the conformation of their cytoplasm and nucleus. We hypothesized that surface chemistry and topography could be engineered to make these differences significant enough. When designing the substrates that would accentuate these differences, we prepared surfaces carrying cell adhesive biological cues arranged in specific patterns. Collagen type I and poly(lactic a...
Microfibrous scaffolds from poly(L-lactide-co-epsilon-caprolactone) blended with xeno-free collagen/hyaluronic acid for improvement of vascularization in tissue engineering applications

Success of 3D tissue substitutes in clinical applications depends on the presence of vascular networks in their structure. Accordingly, research in tissue engineering is focused on the stimulation of angiogenesis or generation of a vascular network in the scaffolds prior to implantation. A novel, xeno-free, collagen/hyaluronic acid-based poly(L-lactide-co-epsilon-caprolactone) (PLC/COL/HA) (20/9.5/0.5 w/w/w) microfibrous scaffold was produced by electrospinning. Collagen types I and III, and hyaluronic acid...
Micropatterned Surfaces Expose the Coupling between Actin Cytoskeleton-Lamin/Nesprin and Nuclear Deformability of Breast Cancer Cells with Different Malignancies.
Antmen Altunsoy, Ezgi; Hasirci, Vasif (2021-01-01)
Mechanotransduction proteins transfer mechanical stimuli through nucleo‐cytoskeletal coupling and affect the nuclear morphology of cancer cells. However, the contribution of actin filament integrity has never been studied directly. It is hypothesized that differences in nuclear deformability of cancer cells are influenced by the integrity of actin filaments. In this study, transparent micropatterned surfaces as simple tools to screen cytoskeletal and nuclear distortions are presented. Surfaces decorated wit...
COMPUTATIONAL MECHANICS FOR SOFT BIOLOGICAL TISSUES
Altun, Cem; Dal, Hüsnü; Department of Mechanical Engineering (2023-1-17)
Computational biomechanics is an active research area, not only to understand the mechanisms behind the behaviours of biological tissues but also to develop medical techniques for surgeries, rehabilitations, and diseases. The thesis mainly composed of two parts namely, growth-induced instabilities and dispersion-type anisotropic viscoelasticity for soft biological tissues. In the first part of the thesis, planar growth-induced instabilities for a three-dimensional bilayer-type confined tissue is examined. F...
Investigation of cell migration and proliferation in agarose based hydrogels for tissue engineering applications
Vardar, Elif; Hasırcı, Nesrin; Hasırcı, Vasıf Nejat; Department of Biomedical Engineering (2010)
Hydrogels are three dimensional, insoluble, porous and crosslinked polymer networks. Due to their high water content, they have great resemblance to natural tissues, and therefore, demonstrate high biocompatibility. The porous structure provides an aqueous environment for the cells and also allows influx of nutrients needed for cellular viability. In this study, a natural biodegradable material, agarose (Aga), was used and semi-interpenetrating networks (semi-IPN) were prepared with polymers having differen...
