| 1 | Polydopamine and collagen coated micro-grated polydimethylsiloxane for human mesenchymal stem cell culture显示文摘Natural tissues contain highly organized cellular architecture.One of the major challenges in tissue engineering is to develop engineered tissue constructs that promote cellular growth in physiological directionality.To address this issue,micro-patterned polydimethylsiloxane(PDMS)substrates have been widely used in cell sheet engineering due to their low microfabrication cost,higher stability,excellent biocompatibility,and most importantly,ability to guide cellular growth and patterning.However,the current methods for PDMS surface modification either require a complicated procedure or generate a non-uniform surface coating,leading to the production of poor-quality cell layers.A simple and efficient surface coating method is critically needed to improve the uniformity and quality of the generated cell layers.Herein,a fast,simple and inexpensive surface coating method was analyzed for its ability to uniformly coat polydopamine(PD)with or without collagen on micro-grated PDMS substrates without altering essential surface topographical features.Topographical feature,stiffness and cytotoxicity of these PD and/or collagen based surface coatings were further analyzed.Results showed that the PD-based coating method facilitated aligned and uniform cell growth,therefore holds great promise for cell sheet engineering as well as completely biological tissue biomanufacturing. | Dhavan Sharma Wenkai Jia Fei Long Shweta Pati Qinghui Chen Yibing Qyang Bruce Lee Chang Kyong Choi Feng Zhao | 2019 | Bioactive Materials2019，4，1： | 4 |

| 3 | Perfusability and immunogenicity of implantable pre-vascularized tissues recapitulating features of native capillary network显示文摘Vascularization is a key pre-requisite to engineered anatomical scale three dimensional(3-D)constructs to ensure their nutrient and oxygen supply upon implantation.Presently,engineered pre-vascularized 3-D tissues are limited to only micro-scale hydrogels,which meet neither the anatomical scale needs nor the complexity of natural extracellular matrix(ECM)environments.Anatomical scale perfusable constructs are critically needed for translational applications.To overcome this challenge,we previously developed pre-vascularized ECM sheets with long and oriented dense microvascular networks.The present study further evaluated the patency,perfusability and innate immune response toward these pre-vascularized constructs.Macrophage-co-cultured prevascularized constructs were evaluated in vitro to confirm micro-vessel patency and perturbations in macrophage metabolism.Subcutaneously implanted pre-vascularized constructs remained viable and formed a functional anastomosis with host vasculature within 3 days of implantation.This completely biological pre-vascularized construct holds great potential as a building block to engineer perfusable anatomical scale tissues. | Dhavan Sharma Archita Sharma Linghao Hu Te-An Chen Sarah Voon Kayla J.Bayless Jeremy Goldman Alex J.Walsh Feng Zhao | 2023 | Bioactive Materials2023，，12： | 0 |
