TLDR
A review of biomaterials currently used to improve cellular functions in 3D culture and the contributions of 3D cell culture to cancer research, stem cell culture and drug and toxicity screening can be found in this article.
Abstract
The process of evaluating the efficacy and toxicity of drugs is important in the production of new drugs to treat diseases. Testing in humans is the most accurate method, but there are technical and ethical limitations. To overcome these limitations, various models have been developed in which responses to various external stimuli can be observed to help guide future trials. In particular, three-dimensional (3D) cell culture has a great advantage in simulating the physical and biological functions of tissues in the human body. This article reviews the biomaterials currently used to improve cellular functions in 3D culture and the contributions of 3D culture to cancer research, stem cell culture and drug and toxicity screening.

An interplay of matrix stiffness, dimensionality and adhesivity on cellular behavior

- 09 Feb 2023 - 
TL;DR: In this paper , the stiffness of poly(ethylene glycol) diacrylate (PEGDA)-gelatin methacryloyl (GelMA) hydrogels with lower concentration of GelMA is lower than that with higher GelMA; further, those with higher overall concentration of polymers retain their mechanical integrity and do not degrade even after 7 d.

Drug penetration in solid tumours

TL;DR: The evidence that indicates that the distribution of many anticancer drugs in tumours is incomplete is summarized, and strategies that might be used either to improve drug penetration through tumour tissue or to select compounds based on their abilities to penetrate tissue are suggested, thereby increasing the therapeutic index.
