Biomedical Image Analysis Applications: Spheroids, Organoids & Embryoid Body Analysis
Spheroids, organoids and embryoid bodies are highly valuable 3D culture techniques that are widely used in research for all different kinds of applications. Combined with biomedical imaging and image analysis, those 3D cultures can give valuable insights for research and clinics. Data extracted from biomedical image analysis applications inform researchers of essential biological mechanisms and processes that underpin many diseases and press medical challenges. Thus, innovative medical image processing is necessary to conduct and complete these experiments. Various biomedical image analysis applications rely on high-throughput imaging systems as well as image analysis software – especially for complex diseases like cancer, where studying 3D cell culture yields more physiologically relevant information than focusing on single tumor cells.
This blog post will briefly review the differences of 3D cell cultures, including spheroids, organoids, and embryoids and will further discuss why those are used in research. It will also go over various life science solutions to help perform diverse biomedical image analysis applications efficiently and robustly.
Spheroids are simple in-vitro structures produced from one cell type and can mimic specific tissue structures. Because of this benefit, spheroids are good models for cell-to-cell interaction and cancer cell and tumor research . Spheroid formation occurs through self-assembling cell aggregation . 3D spheroid cultures can be maintained longer than single cells and are helpful, for example, for testing the long-term effects of cancer drugs on tumors or understanding neurodegenerative diseases, making spheroids an interesting target of biomedical image analysis .
Organoids are complex 3D in vitro clusters consisting of multiple cell types and thereby mimic organs. Those structures are used not only to study organ function , but also to give insight into biological systems, including information on an organ’s function, growth, organization, and dynamics. Organoid models are particularly suited for disease research, understanding growth and development in organisms, cell function studies, and drug screening experiments . Biomedical image analysis of those structures can provide direct observation and extraction of quantitative data crucial to the life sciences .
Embryonic stem cells aggregate and form embryoid bodies, which can serve as a 3D cell model . Embryoids are valuable in biomedical research because they have the potential to differentiate into a diverse array of specialized cells, and this high level of spontaneous differentiation makes embryoids a prime model of development .
