An easily made, low-cost, tissue-like ultrasound phantom material.
Ultrasound phantoms are generally of two types. One mimics the acoustic properties of tissue (with regard to the speed of sound, average attenuation, etc.). The main purpose of the other is to approximate the sonographic appearance of tissue. The latter is often used as a biopsy training aid. Those which mimic the acoustic properties of tissue have been constructed of agar with suspended graphi...
متن کاملVascularized Tissue Constructs
A major challenge in tissue engineering is the lack of proper vascularization of the fabricated tissue constructs. Microscale technologies, especially microfluidic systems, provide new opportunities to overcome the challenge of developing artificial micro-vasculatures. In this chapter, the application of microfluidic systems for generating vascularized tissue constructs by using microfluidic pl...
متن کاملVasculogenic dynamics in 3D engineered tissue constructs
Implantable 3D engineered vascular tissue constructs can be formed by co-culturing endothelial and fibroblast cells on macroporous scaffolds. Here we show that these constructs can be used for studying the dynamics of neovascular formation in-vitro by a combination of live confocal imaging and an array of image processing and analysis tools, revealing multiple distinct stages of morphogenesis. ...
متن کاملSmooth Muscle-Like Tissue Constructs with Circumferentially Oriented Cells Formed by the Cell Fiber Technology
The proper functioning of many organs and tissues containing smooth muscles greatly depends on the intricate organization of the smooth muscle cells oriented in appropriate directions. Consequently controlling the cellular orientation in three-dimensional (3D) cellular constructs is an important issue in engineering tissues of smooth muscles. However, the ability to precisely control the cellul...
متن کاملGrowing tissue-like constructs with Hep3B/HepG2 liver cells on PHBV microsphere scaffold
In this study, a solvent evaporation technique was used to fabricate poly(3hydroxybutyrate-co-3-hydroxyvalerate) (PHBV, 8% PHV) microspheres as scaffold to guide liver cell growth. Human hepatoma cell lines, HepG2 and Hep3B, were cultured in vitro on both the microspheres and polymer films. SEM and optical microscope images showed that multilayer cells were formed among the microspheres to brid...
