Fig. 6. Distribution of apoptotic germ cells in P7 testis cords. (A) Section of wild-type P7 testis probed for galectin 1 mRNA by in situ hybridisation. (B) Adjacent serial section labelled by TUNEL and counterstained with Methyl Green. Apoptotic bodies appear as brown spots. (C) Next serial section stained by galectin 1 immunohistochemistry. A group of testis cords is shown to the right of each panel at a higher magnification to illustrate the high (H), medium (M) and low (L) categories of signal intensity. Segments of testis cord that contain apoptotic germ cells (labelled by TUNEL in B) are outlined in each panel.
