Figure 4From: Ultrastructural localization of extracellular matrix proteins of the lymph node cortex: evidence supporting the reticular network as a pathway for lymphocyte migrationFibrillar collagen immunoelectron microscopy. Collagen I (A) and Collagen III (B) are both easily detected within the reticular fiber of these serial sections. Label particles are more numerous in longitudinal section of reticular fiber (B, left RF) than in cross-section (B, right RF) (see discussion). (Same magnification for images A and B).Back to article page
