Figure 8.
At muscle end regions, MARP and TSP-4 transcripts accumulate at adjacent locations. Consecutive sections (chest muscles, above heart) from an E14.5 embryo were hybridized for MLP, MARP, and TSP-4 transcript, as indicated. Note similar distribution and complementarity of MARP and TSP-4 labeling patterns (two examples are indicated by the arrowheads). In addition to regions adjacent to muscle ends, TSP-4 transcript also accumulated in chondrogenic areas (one example indicated by the asterisk). Bar, 500 μm.
