Thymic tissue slices: a versatile model for the study of T cell selection in situ. In an effort to develop a tractable experimental system to study T cell development within the 3D tissue environment of the thymus, we and others have turned to a thymic slice model (9, 10) (Figure 1).This approach uses vibratome-cut slices of thymic tissue, and was inspired by decades of successful studies It's still technically possible that Trump could choose a new No. 2.
