• To explore cellular interactions in a controlled environment.

Methods Used

• Isolation and treatment of embryonic thymic lobes.
• Disaggregation to produce stromal cell preparations.
• Aggregation of cells to form reaggregate cultures.
• Incubation and observation of culture development.

Main Results

• Reaggregate cultures form intact structures within 18 hours.
• CD4 positive and CD8 positive T-cell subsets are generated.
• Method allows for the study of positive and negative selection.
• Utilization of TCR transgenic fibrocytes for further investigations.

Conclusions

• The protocol effectively demonstrates T-cell differentiation.
• Reaggregate cultures provide a valuable tool for immunological studies.
