- Fabrication of large perfusable macroporous cell-laden hydrogel scaffolds using microbial transglutaminase.

Electronic address: drjssun@gmail.com.AbstractIn this study, we developed a method to fabricate large, perfusable, macroporous, cell-laden hydrogels. This method is suitable for efficient cell seeding, and can maintain sufficient oxygen delivery and mass transfer. We first loaded three types of testing cells (including NIH 3T3, ADSC and Huh7) into gelatin hydrogel filaments, then cross-linked the cell-laden gelatin hydrogel filaments using microbial transglutaminase (mTGase). In situ cross-linking by mTGase was found to be non-cytotoxic and prevented the scattering of the cells after delivery. The gelatin hydrogel constructs kept the carried cells viable; also, the porosity and permeability were adequate for a perfusion system. Cell proliferation was better under perfusion culture than under static culture. When human umbilical vein endothelial cells were seeded into the constructs, we demonstrated that they stably formed an even coverage on the surface of the hydrogel filaments, serving as a preliminary microvasculature network. We concluded that this method provides a viable solution for cell seeding, oxygen delivery, and mass transfer in large three-dimensional (3-D) tissue engineering. Furthermore, it has the potential for being a workhorse in studies involving 3-D cell cultures and tissue engineering.

- A three-dimensional co-culture model of the aortic valve using magnetic levitation.
- Tseng H, Balaoing LR, Grigoryan B, Raphael RM, Killian TC, Souza GR, Grande-Allen KJ.Author information Department of Bioengineering, Rice University, Houston, TX 77005, USA; Nano3D Biosciences, Houston, TX 77030, USA.AbstractThe aortic valve consists of valvular interstitial cells (VICs) and endothelial cells (VECs). While these cells are understood to work synergistically to maintain leaflet structure and valvular function, few co-culture models of these cell types exist. In this study, aortic valve co-cultures (AVCCs) were assembled using magnetic levitation and cultured for 3 days. Immunohistochemistry and quantitative reverse-transcriptase polymerase chain reaction were used to assess the maintenance of cellular phenotype and function, and the formation of extracellular matrix. AVCCs stained positive for CD31 and α-smooth muscle actin (αSMA), demonstrating that the phenotype was maintained. Functional markers endothelial nitric oxide synthase (eNOS), von Willebrand factor (VWF) and prolyl-4-hydroxylase were present. Extracellular matrix components collagen type I, laminin and fibronectin also stained positive, with reduced gene expression of these proteins in three dimensions compared to two dimensions. Genes for collagen type I, lysyl oxidase and αSMA were expressed less in AVCCs than in 2-D cultures, indicating that VICs are quiescent. Co-localization of CD31 and αSMA in the AVCCs suggests that endothelial-mesenchymal transdifferentiation might be occurring. Differences in VWF and eNOS in VECs cultured in two and three dimensions also suggests that the AVCCs possibly have anti-thrombotic potential. Overall, a co-culture model of the aortic valve was designed, and serves as a basis for future experiments to understand heart valve biology.

- Growth hormone and retinal ganglion cell function: QNR/D cells as an experimental model.
- Martínez-Moreno C1, Andres A1, Giterman D1, Karpinski E1, Harvey S2.Author information 1Department of Physiology, University of Alberta, Edmonton T6G 2H7, Canada.2Department of Physiology, University of Alberta, Edmonton T6G 2H7, Canada. Electronic address: steve.harvey@ualberta.ca.AbstractRetinal ganglion cells (RGCs) have been shown to be sites of growth hormone (GH) production and GH action in the embryonic (embryo day 7, ED7) chick neural retina. Primary RGC cell cultures were previously used to determine autocrine or paracrine actions of GH in the retina, but the antibody used in their immunopanning (anti-Thy-1) is no longer available. We have therefore characterized an immortalized neural retina (QNR/D) cell line derived from ED7 embryonic quail as a replacement experimental model. These cells express the GH gene and have GH receptor (GHR)-immunoreactivity. They are also immunoreactive for RGC markers (islet-1, calretinin, RA4) and neural fibers (neurofilament, GAP 43, vimentin) and they express the genes for Thy-1, neurotrophin 3 (NTF3), neuritin 1 (NRN1) and brn3 (POU4F). These cells are also electrically active and therefore resemble the RGCs in the neural retina. They are also similarly responsive to exogenous GH, which induces overexpression of the neurotrophin 3 and insulin-like growth factor (IGF) 1 genes and stimulates cell survival, as in the chick embryo neural retina. QNR/D cells are therefore a useful experimental model to assess the actions of GH in retinal function.
