Detailed explanation-1: -Lymphoid progenitors which have developed from hematopoietic stem cells in the bone marrow migrate to the thymus to complete their antigen-independent maturation into functional T cells . In the thymus, T cells develop their specific T cell markers, including TCR, CD3, CD4 or CD8, and CD2.
Detailed explanation-2: -The developing progenitors within the thymus, also known as thymocytes, undergo a series of maturation steps that can be identified based on the expression of different cell surface markers.
Detailed explanation-3: -The thymus supports the differentiation of multiple distinct T cell subsets that play unique roles in the immune system. CD4 and CD8 / T cells, / T cells, NKT cells, Treg, and IEL all develop in and must leave the thymus to provide their functions elsewhere in the body.
