Introduction/Rationale: Prostate cancer progression is influenced by the tumor microenvironment and soluble signaling factors. Mouse embryonic stem cells (mESCs) secrete cytokines such as LIF, BMPs, and TGF-β that regulate cell proliferation and differentiation. Previous reports suggest these signals can alter tumor behavior through paracrine interactions. This study investigates whether mESC-derived factors can modulate the proliferation of MyC-CaP prostate cancer cells and serve as a model for identifying natural inhibitors of tumor growth.
Methods: MyC-CaP cells were cultured in proximity to mESCs using a transwell co-culture system to allow paracrine signaling without direct contact. Cell viability and morphology were monitored microscopically and quantified using standard viability assays. Future experiments will incorporate a hyaluronic acid hydrogel scaffold to model the extracellular matrix and improve spatial organization for more physiologic signaling assessment.
Results: Preliminary co-culture data suggest reduced MyC-CaP proliferation when exposed to mESC-secreted factors compared with monoculture controls. Morphologic changes consistent with decreased proliferation and differentiation were observed. Additional assays are underway to quantify cytokine levels and confirm reproducibility under hydrogel conditions.
Conclusion: mESC-derived signals may suppress MyC-CaP prostate cancer cell proliferation through paracrine cytokine activity. Incorporating a hydrogel microenvironment will further define the mechanisms by which stem cell secretions influence tumor behavior, providing insight into potential translational applications for cancer modulation.
