The ontogeny of antigen-presenting cells in fetal thymus evaluated by MLR stimulation
Abstract
This study demonstrates that cells with the characteristics of antigen-presenting cells (APC) are present in murine thymus from as early as 14 days gestation, around the time that T lymphopoiesis is initiated in the embryo. Thymic APC were identified as la+ adherent cells capable of presenting alloantigens to T cells in MLC. The possible role of these cells in thymocyte differentiation is discussed.
