The Influence of the Presence and Timing of Stimuli on Differentiation Control
In April, I focused on examining the conditions of culture systems related to germ cell differentiation. Specifically, I investigated the behavior of cells when no external stimuli are provided, as well as the impact of the type and timing of stimuli on differentiation.
Under conditions without stimuli, there was a tendency to maintain an undifferentiated state. However, differentiation did not completely stop, and in some conditions, a certain degree of differentiation was observed. This suggests the possibility of a probabilistic aspect in the progression of differentiation.
There were also cases where clear differentiation induction was observed by adding specific stimuli. At the same time, it was found that the type, amount, and timing of stimuli caused significant differences in the state of the cells. When the strength or timing of the stimuli was inappropriate, it was difficult to achieve the desired differentiation pattern, indicating the need for precise condition setting.
I emphasize the design of factor administration along a timeline based on the developmental process in vivo. The results of this experiment particularly suggest that the “timing” of stimuli plays a significant role in determining the direction of differentiation. I plan to focus on this aspect in future investigations.
