Final answer:
Lymphoid stem cells differentiate into T lymphoblasts, which mature into naïve T cells and then Cd₄⁺/Cd₈⁺ T cells.
Step-by-step explanation:
Lymphoid stem cells differentiate into T lymphoblasts, which then mature into naïve T cells and subsequently differentiate into Cd₄⁺/Cd₈⁺ T cells. This differentiation process occurs primarily in the thymus. T cells are a type of lymphocyte that plays a crucial role in the cell-mediated immune response.
