Anchorage of muscle cells to the extracellular matrix is crucial for a range of fundamental biological processes including migration, survival and differentiation. Three-dimensional (3D) culture has been proposed to provide a more physiological in vitro model of muscle growth and differentiation than routine 2D cultures. However, muscle cell adhesion and cell-matrix interplay of engineered musc...
The increasing interest in studying the interactions between cells and the extracellular matrix (ECM) has created a need for high throughput low-cost three-dimensional (3D) culture systems. The recent development of tubeless microfluidics via passive pumping provides a high throughput microchannel culture platform compatible with existing high throughput infrastructures (e.g., automated liquid ...
It is well recognized that one of the major drawbacks of using traditional two dimensional cultures to model the living systems is inaccurately reflecting the physiological manner in which modulators, nutrients, oxygen, and metabolites are applied and removed. Moreover, the two dimensional culture system poorly reflects how different cell types interact with each other in the same microenvironm...
Multicellular 3D culture and interaction with stromal components are considered essential elements in establishing a 'more clinically relevant' tumor model. Matrix-embedded 3D cultures using a microfluidic chip platform can recapitulate the microscale interaction within tumor microenvironments. As a major component of tumor microenvironment, cancer-associated fibroblasts (CAFs) play a role in c...
U ntil recently, basic research testing the efficacy of novel anti-cancer drugs was performed on cells grown on two-dimensional (2D) glass or plastic platforms. An emerging view finds that traditional 2D cell culture may not accurately mimic the three-dimensional (3D) environment in which cancer cells reside. Specifically, the unnatural 2D environment may provide inaccurate data regarding the p...
We reported previously that bone morphogenetic protein 7 (BMP7) could induce epithelial-mesenchymal transition (EMT) in PC-3 prostate cancer cells grown in tissue culture plates. In this study, we examined BMP7-induced morphological and molecular expression changes that are characteristic of EMT using these cells under both two- (2D) and three-dimensional (3D) culture conditions. Filamentous ou...
The use of biopolymers as a three dimensional (3D) support structure for cell growth is a leading tissue engineering approach in regenerative medicine. Achieving consistent cell seeding and uniform cell distribution throughout 3D scaffold culture in vitro is an ongoing challenge. Traditionally, 3D scaffolds are cultured within tissue culture plates to enable reproducible cell seeding and ease o...
BACKGROUND Currently available vascular grafts have been limited by variable patency rates, material availability, and immunological rejection. The creation of a tissue-engineered vascular graft (TEVG) from autologous stem cells would potentially overcome these limitations. As a first step in creating a completely autologous TEVG, our objective was to develop a novel system for culturing undiff...
Cells in a functional tissue display a highly interactive relation with their neighboring cells and associated biochemical milieu. Serious disruption in the existing homeostatic balance in the extra-cellular matrix (ECM) may lead to abnormal response by the cells. With insufficient understanding of Cell-ECM interaction and in absence of simple tools for in vitro cell-culture in 3D, we still hav...
Three-dimensional (3D) cell culture has been reported to increase the therapeutic potentials of mesenchymal stem cells (MSCs). In this study, we aimed to investigate the therapeutic effects of 3D spheroids of human adipose-derived MSCs for acute kidney injury (AKI). In vitro studies indicated that 3D spheroids of MSCs produced higher levels of extracellular matrix proteins (including collagen I...
