Discussion

New framework categorizes thymic epithelial cells by function and structure, emphasizing thymocyte development and immune system architecture.

Identifying 11 types of thymic epithelial cells aids understanding of thymopoiesis and T cell development, impacting immune response.
This classification is based on unique ultrastructural features observed in the thymic cortex and medulla, showing clear spatial organization.
Comprehensive framework integrates microanatomy with functional hypotheses, indicating the critical roles of TEC diversity in T cell maturation.
Significantly, the system is adaptable for future research into thymic dysfunction and its effects on immune response, highlighting the need for ongoing investigation.

Vodopyanov et al. (2025) studied this question.
