Over the past month, I continued working on a long-term culture system aimed at modeling early germline development. This time, I noticed encouraging signs that suggest a possible transition toward a more advanced developmental state, though reproducibility still needs to be carefully validated.
Interestingly, the surrounding signaling context might be playing a role in this progression. While the mechanisms remain unclear, these observations have led me to reconsider how specific signaling environments may influence developmental outcomes.
Observing fluctuations in cell behavior over extended culture made me think about how developmental environments are tightly regulated in vivo, and how we might better mimic those dynamics in vitro.
In particular, it made me reflect on how cell-cell compatibility can influence long-term culture outcomes. It also reminded me that not only chemical conditions but also the cellular composition and interactions can shape developmental trajectories in vitro.
I plan to continue refining the system and exploring ways to support cellular health over extended periods.
