Fig. 4From: Protein kinase C delta null mice exhibit structural alterations in articular surface, intra-articular and subchondral compartmentsHistological analysis of the interface between the growth plate and metaphysis in protein kinase C delta (PKC-δ)+/+ and PKC-δ−/− mice. a, b Alcian blue staining was performed in tibia with Ponceau S counterstain. Arrow points to the area where the matrix of the growth plate is located. c Measurement of the height of growth plates by alcian blue staining regions in PKC-δ+/+ and PKC-δ−/− miceBack to article page
