Follicular lymphomas (FLs) account for 35-40% of all adult lymphomas. Treatment typically involves chemotherapy combined with the anti-CD20 monoclonal antibody (MAb) rituximab (RTX). The development of the type II anti-CD20 MAb obinutuzumab (GA101) aims to further improve treatment. Here, using FL cells we show that RTX and GA101 display a similar activity on RL cells cultured in 2D. However, 2...

OBJECTIVE Development of an artificial salivary gland will benefit patients with xerostomia after radiation therapy for upper respiratory cancer. The goal is to devise a three-dimensional (3D) culture system in which salivary cells differentiate into polarized acini that express essential biomarkers and directionally secrete alpha-amylase. Differentiated acini-like structures in a 3D biomateria...

The human body contains different endothelial cell types and differences in their angiogenic potential are poorly understood. We compared the functional angiogenic ability of human aortic endothelial cells (HAECs) and human umbilical vein endothelial cells (HUVECs) using a three-dimensional (3D) microfluidic cell culture system. HAECs and HUVECs exhibited similar cellular characteristics in a 2...

Fragmin/protamine nanoparticles (F/P NPs) have been used as carriers for the preservation and controlled release of fibroblast growth factor (FGF)-2 and various cytokines in human plasma (HP). This study tested an HP-Dulbecco's modified Eagle's medium (DMEM) gel as a three-dimensional (3D) culture for the expansion of adipose tissue-derived multilineage stromal cells (ASCs) and bone marrow-deri...

Liver sinusoidal endothelial cells (SECs) are generally refractory to extended in vitro culture. In an attempt to recreate some features of the complex set of cues arising from the liver parenchyma, we cocultured adult rat liver SECs, identified by the expression of the marker SE-1, with primary adult rat hepatocytes in a 3D culture system that provides controlled microscale perfusion through t...

Purpose To establish a simplified three-dimensional (3D) meibomian gland culture model using a meibomian gland epithelial cell (HMGEC) line that might be a useful tool to gain deeper insights into meibomian gland dysfunction. For this purpose, 3D differentiation patterns and growth characteristics of HMGECs were studied on various membranes/scaffolds as well as in hanging drops. Methods Sever...

Since the 1970s, the limitations of two dimensional (2D) cell culture and the relevance of appropriate three dimensional (3D) cell systems have become increasingly evident. Extensive effort has thus been made to move cells from a flat world to a 3D environment. While 3D cell culture technologies are meanwhile widely used in academia, 2D culture technologies are still entrenched in the (pharmace...

The effects of radiation in two-dimensional (2D) cell culture conditions may not recapitulate tissue responses as modeled in three-dimensional (3D) organotypic culture. In this study, we determined if the frequency of radiation-induced transformation and cancer progression differed in 3D compared to 2D culture. Telomerase immortalized human bronchial epithelial cells (HBECs) with shTP53 and mut...

This paper presents a 3D reality modelling system, applying lasers and digital photography to create superaccurate photo-realistic three-dimensional worlds. A key feature of the 3D reality system is its flexibility. It can be used with all common long-range scanners and digital or video cameras, without the need of any pre-calibration or static arrangement between the different sensors. The sys...

An engineered three dimensional (3D) in vitro cell culture system was designed with the goal of inducing and controlling in vitro osteogenesis in a reproducible manner under conditions more similar to the in vivo bone microenvironment than traditional two-dimensional (2D) models. This bioreactor allows efficient mechanical loading and perfusion of an original cubic calcium phosphate bioceramic ...
