Biomechanics Of Porcine Renal Artery And The Development Of A Replacment Vessel, Mohamed Gabr

Theses and Dissertations

Mechanical characterization of biological soft tissues is essential in the field of biomedical engineering. In this study several loading experiments have been performed to efficiently characterize the passive mechanical response of both native porcine renal arteries and newly developed tissue constructs. The first aim of these studies is to determine whether there is a difference in mechanical response between the main renal artery and its first branch. After fitting the bi-axial data to a Holzapfel-type constitutive model, the results show that there is no statistical difference between the model parameters for renal artery and the first branch. The only significant …

Toward Directing Cell Fate: Carbon Nanotubes As Modulators Of Extracellular And Transporters Of Intracellular Cues, Qingsu Cheng

Theses and Dissertations

The unique properties of CNTs lead CNTs attractive in biological engineering applications. It is expected to use CNT based biomaterials for clinic use in the near future. CNTs can be used to tune cellular fate through bother extracellular pathway and intracellular pathway. CNT based biomaterials has been applied into bone, nerves, and cardiovascular system. There has also been progress in the use of CNTs in controlling cellular alignment, to enhance tissue regeneration, growth factor delivery and gene delivery.

Pluripotent stem cells (hPSCs) offer a promising tool in tissue engineering strategies, as their differentiated derivatives can be used to reconstruct most …
