From: Expression of nuclear factor kappa B in ovine maternal inguinal lymph nodes during early pregnancy
Representative immunohistochemical localization of p65 protein in the inguinal lymph nodes from non-pregnant ewes and pregnant ewes (n = 6 for each group). Lymph node is divided into an outer cortex (CO) and an inner medulla (ME). Lymph enters the convex through the subcapsular sinus (SS) and trabeculae (TR) around the lymphoid nodules (LN), and flows into the medulla through the lymph sinus (LS) around the medullary cord (MC). Note: HE = stained by haematoxylin and eosin; Clt = Negative control; DN16 = day 16 of the estrous cycle; DP13 = day 13 of pregnancy; DP16 = day 16 of pregnancy; DP25 = day 25 of pregnancy. Bar = 20 μm
