What are neuroendocrine tumors?
Neuroendocrine tumors are a diverse group of tumors that arise from neuroendocrine cells, which have traits similar to both nerve cells and hormone-producing cells.
Why use 3D spheroids for research?
3D spheroids provide a more accurate representation of tumor biology compared to traditional 2D cell cultures, allowing for better drug response studies.
How are spheroids monitored during growth?
Spheroid growth is monitored using phase contrast microscopy to assess their size and integrity over time.
What is HistoGel embedding?
HistoGel embedding is a technique used to preserve tissue samples for histological analysis, allowing for detailed examination of cellular structures.
What advantages does this method offer?
The method is simple, reliable, and cost-effective, making it accessible for researchers studying neuroendocrine tumors.
