About this Research Topic
The two-dimensional (2D) cell cultures are commonly used for various testing and research applications such as drug testing, disease modelling, toxicity studies, fundamental biological studies, and tissue engineering applications. However, the use of such simple, conventional 2D cell culture is unable to adequately recapitulate the in vivo cell-cell and cell-matrix interactions found in native three-dimensional (3D) tissues and it has been reported that numerous types of cells have expressed different phenotypes and genomic profiles in 2D vs 3D cell culture. Hence, the fabrication of in-vitro 3D tissue models would bring about increased complexity that may improve the reliability and accuracy of test outcomes. Successful fabrication of in-vitro tissue models is dependent on two critical aspects – large-scale cell manufacturing (growing cells in vast quantities within a homogeneous physical and chemical environment) and advanced manufacturing platform (highly-automated fabrication of in-vitro tissue models with high throughput rates and repeatability).
Over the years, the field of toxicology testing has evolved tremendously from the use of animal models to 2D human cell cultures and finally the adaptation of in-vitro 3D human testing models. It is important that these in-vitro 3D human testing models predicts the human responses in an accurate and reliable manner. Hence, large-scale cell manufacturing and advanced manufacturing platform are necessary in ensuring the consistency of the fabricated in-vitro 3D human testing models. The goal of this Research Topic is to focus on the recent developments in cell processing techniques and advanced manufacturing approaches for fabrication of 3D in-vitro human tissue models.
The Research Topic aims to solicit manuscripts that describe the current state-of-the-arts, highlight recent developments and major accomplishments, future challenges, and directions towards fabrication of 3D in-vitro human tissue models, specifically in large-scale cell manufacturing and advanced manufacturing platform. Original Research, Reviews, Perspectives and Opinions summarizing the current state and future directions of the field are particularly welcome in this collection. This article collection thrives to inspire, inform and provide direction and guidance to researchers in the field.
