The Postembryonic Development of the Immunological Barrier in the Chicken Spleens

Figure 1

The BSB against the carbon particle in different ages of the chicken spleens with HE staining. (a, g) The histological structure of the chicken spleens at 1 d after hatching. (b, h) The histological structure of the chicken spleens at 7 d. (c, i) The histological structure of the chicken spleens at 14 d. (d, j) The histological structure of the chicken spleens at 21 d. (e, k) The histological structure of the chicken spleens at 35 d. (f, l) The histological structure of the chicken spleens at 60 d. The first two lines are paraffin sections dewaxing without HE staining. CA: central artery; LN: lymph nodule; RP: red pulp; PALS: periarteriolar lymphatic sheath.
