Three-dimensional culture is rapidly developing but still not as common as other model systems. We do not have any books dedicated to three-dimensional culture systems in the Arnold library, but I hope the reviews in the class reading materials and the methods papers and protocols on lab websites listed below can guide you to further information.
Papers about methods used in 3D culture:

Three-dimensional culture of human cells
Lecture videos are available for viewing in the left column. They will be used during class to illustrate points about modeling cancer progression in 3D culture systems.
1. Great review of the various types of 3D culture. Pros and cons and applications of this model system.
2. Comprehensive review of the important features of epithelial structures grown in 3D basement membrane cultures, and how such models have been used to investigate the mechanisms associated with tumour initiation and progression.
3. An excellent short essay that gives an overview of the various 3D culture systems. Covers lessons that are guiding the development of these 3D models, and technical challenges and improvements with an emphasis on imaging.
4. Short interesting review on the effect of the microenvironment on normal and malignant cells. Includes a good historical perspective and though it is a bit old it also covers tumor stem cells, which is a concept that will be useful for our next lecture.
1. Article d escribing a new biomimetic model that may provide a broadly applicable 3D culture system to study the effect of microenvironmental conditions on tumor malignancy in vitro and in vivo.

2. Review describing the critical roles that microenvironmental context and tissue architecture play in directing breast development and differentiation an in determining the response to oncogenic insults.

Tumor Microenvironment (TMEN) monthly discussion meetings take place on campus. They are from 5-6pm on Thursdays in the Arnold building M1-A305/307. Organized by the PPCR/SPORE, contact Margery Kiso for more information.
