Paper-supported 3D cell culture for tissue-based bioassays.
Fundamental investigations of human biology, and the development of therapeutics, commonly rely on 2D cell-culture systems that do not accurately recapitulate the structure, function, or physiology of living tissues. Systems for 3D cultures exist but do not replicate the spatial distributions of oxygen, metabolites, and signaling molecules found in tissues. Microfabrication can create architect...
متن کاملPaper-Supported Three-Dimensional Cell Culture for Tissue-Based Bioassays
Methods. Cells and reagents We purchased MDA-MB-231 cells from ATCC and primary IMR90, HDF and primary HUVEC cells from Lonza. MDA-MB-231, IMR-90, HDF and LLC cells were cultured in Eagle’s minimal Essential medium (MEM) from Lonza supplemented with 10% fetal bovine serum (FBS) and 1% GlutaMax (both from Invitrogen). Primary HUVEC cells were cultured in endothelial growth medium (EGM-2, Lonza)....
متن کاملHydrodynamic 3D Culture for Bone Tissue Engineering
Bone tissue engineering provided a promising approach for treatment of large bone defects resulting from maladies such as birth defects, trauma, or tumor resection. In vitro culture of a porous scaffold seeded with osteoprogenitor cells may enhance its bone regeneration potential. In this chapter, we describe the design of a novel perfusion bioreactor system with oscillatory flow for cultivatin...
متن کاملMetabolic response of lung cancer cells to radiation in a paper-based 3D cell culture system.
This work demonstrates the application of a 3D culture system-Cells-in-Gels-in-Paper (CiGiP)-in evaluating the metabolic response of lung cancer cells to ionizing radiation. The 3D tissue-like construct-prepared by stacking multiple sheets of paper containing cell-embedded hydrogels-generates a gradient of oxygen and nutrients that decreases monotonically in the stack. Separating the layers of ...
متن کاملMultizone Paper Platform for 3D Cell Cultures
In vitro 3D culture is an important model for tissues in vivo. Cells in different locations of 3D tissues are physiologically different, because they are exposed to different concentrations of oxygen, nutrients, and signaling molecules, and to other environmental factors (temperature, mechanical stress, etc). The majority of high-throughput assays based on 3D cultures, however, can only detect ...
