Hypothesis
The study aims to identify significant epithelial signalling pathways and genes involved in the increased lateral cell adhesions of prostate epithelial cells due to stromal signalling.
Conclusion
Stromal cells enhance lateral epithelial cell adhesions in 3D prostate cultures, linked to changes in gene expression related to TGF beta signalling and cytoskeletal activity.
Supporting Evidence
- TGF beta signalling was significantly ranked for both model systems.
- SOX4 was significantly down regulated in both models.
- Several morphology-related gene clusters were identified.
- Stromal cells were shown to increase lateral cell adhesions in 3D cultures.
Takeaway
This study shows that the cells around prostate cells help them stick together better, which is important for how they grow and function.
Methodology
Microarray analysis was used to compare gene expression in primary epithelial cells grown in 3D culture with and without stromal co-culture.
Potential Biases
Potential bias due to the variability in primary cultures and the use of different stromal mixes.
Limitations
The study faced challenges due to heterogeneity in patient samples and the complexity of biological processes.
Participant Demographics
Human prostate tissue samples were obtained from patients with written consent.
