Two-Dimensional (2D) and Three-Dimensional (3D) Cell Culturing in Drug Discovery
Cell culture is an indispensable in vitro tool used to improve our perception and understanding of cell biology, the development of tissue engineering, tissue morphology, mechanisms of diseases and drug action. Efficient cell culturing techniques both in vitro and in vivo allow researchers to design and develop new drugs in preclinical studies. Two-dimensional (2D) cell cultures have been used since 1900s and are still a dominant method in many biological studies. However, 2D cell cultures poorly imitate the conditions in vivo. Recently three-dimensional (3D) cell cultures have received remarkable attention in studies such as drug discovery and development. Optimization of cell culture conditions is very critical in ensuring powerful experimental reproducibility, which may help to find new therapies for cancer and other diseases. In this chapter, we discuss the 2D and 3D cell culture technologies and their role in drug discovery.

Current Advances in Immune Checkpoint Therapy
Although immune checkpoint inhibitors (ICIs) have shown survival benefits for patients with metastatic cancers, some challenges have been under intense study in recent years. The most critical challenges include the side effects and the emergence of resistance. Potential opportunities exist to develop personalized immune checkpoint inhibitor therapy based on biomarker discovery. Combinational therapy involving immune checkpoint inhibitors and other forms of anticancer therapies has varied success. This chapter reviews drugs currently undergoing Phase III clinical trials and others that are FDA-approved. We take a critical look at the combinational strategies and address the ever-present challenge of resistance. Moreover, we review and evaluate the discovery of biomarkers and assess prospects for personalized immune checkpoint therapy.
