2. Fig. 1
Antigen-presenting cell markers and costimulatory molecules within human fetal gut. Immunohistochemistry was used to evaluate the expression of MHC class II (a ), CD14 (b ), CD68 (c ), CD20 (d ), CD83 (e ), CD40 (f ), and CD86 (g ). An isotype-matched control was always included (h ). Representative examples of a total of 25 different tissues are shown. Scale bar = 0.2 mm.

T lymphocytes and costimulatory counterligands within human fetal gut. Immunohistochemistry was used to evaluate the expression of CD3 (a ), CD28 (b ), CD40L (c ), and CTLA-4 (d ). An isotype control was always included (e ). Representative examples of a total of 25 different tissues are shown. Scale bar = 0.2 mm.
