Surface Chemistry Effects on Human Mesenchymal Stem Cells in 2D and 3D Culture

Introduction The maintenance mesenchymal stem cells (MSCs) in an undifferentiated state and subsequently driving their differentiation to a specific lineage in an efficient and scalable manner in an artificial reservoir in vitro is critical for the ultimate clinical success of tissue engineering, regenerative medicine and stem cell research. It is well established that surface chemistry is one of the key factors that can control the cell responses to a material. In this study, we will investigate and compare the effects of different chemical groups on MSCs in 2-D and 3-D culture systems.
