Fig. 2 ZNS5 and Cx43 detect different populations of cells in the fin ray, and are both expressed in newly developing joints. (A) Whole mount staining of ZNS5. (B) Whole mount staining of Cx43. (C) Longitudinal cryosection showing lateral ZNS5 staining and detection of one joint (arrowhead). (D) Longitudinal cryosection showing mesenchymal Cx43 expression and detection of one joint (arrowhead). (E–G) Higher magnification of the joint observed in C and D shown for ZNS5, Cx43, and the overlap. Arrowheads point to joints; arrows indicate the location of bone matrix. L, lateral; M, medial. Scale bars for A–D, 100 μm. Scale bar for E–G, 10 μm.
