Beginning in late embryos, CRISPR tagged gfp::
hum-7 is faintly expressed in embryonic muscle, including the developing body wall muscles and pharynx. Expression in other embryonic tissues, like neuroblasts and epidermis, could not be determined with the CRISPR allele. Staining gfp::
hum-7 adults with monoclonal antibody 5.6 (Miller et al., 1983) which recognizes body wall muscles, confirmed the muscle enrichment.
