Expression Pattern :

Pattern  Antibody staining: Transient nuclear staining in early MS lineage identical to lacZ pattern. Stable nuclear expression begins in the 2 daughters of D at the ~90 cell stage, then C and MS lineages that give rise to body wall muscle cells (bwm). The lone AB bwm appears positive after born. At pretzel stage, nuclear staining in the 6 GLR cells. Staining persists throughout postembryonic development in bwm cells, including post-embryonically born bwm. lacZ reporter gene expression: Multiple constructs with multiple lines. Transient expression in 2 MS daughters and the 4 MS granddaughters. Stable expression begins at ~90 cell stage in two daughters of D. Then on in C, MS lineages that give rise to body wall muscle precursors. At pretzel stage, hlh-1 is also expressed in the 6 GLR cells. positive hybridisation to RNA (in _situ) same as lacZ pattern except RNA appears to go away at bean stage and reappear later in embryogenesis Primary Identifier  Expr56
Remark  90 cell embryo(author) = 88-cell embryo(curator). CeMyoD :Basic Helix-loop-helix transcription factor. Related to the vertebrate MyoD family that is involved in the regulation of striated muscle cell fate.Vertebrate Homologs: Mammalian factors MyoD, MRF-4, Myf-5, myogenin.Invertebrate Homologs: Drosophila protein "Nautilus", sea urchin "SUM-1". Legacy Data: Author "Seydoux GC" "Krause MW". Date 1995-08. Function: Putative null mutation (cc450) of L. Chen and A.Fire suggests important role for CeMyoD in body wall muscle cell function and morphogenesis. CeMyoD is not required for bwm cell fate determination but is for proper bwm cell differentiation

Remark Definition Other Name Public Name Primary Identifier
  The whole period of embryogenesis in the nematode Caenorhabditis elegans, from the formation of an egg until hatching. embryo Ce WBls:0000003
  The C. elegans life stage spanning 520-620min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. The shape of embryo is elongated and tripple fold. A stage between 2-fold embryo and fully-elongated embryo. Also called pretzel embryo or pretzel stage. 3-fold embryo Ce WBls:0000020
  The C. elegans life stage spanning 350-390min after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. Emrbyo elongation started but have not formed comma shape yet. The shape of embryo looks like a lima bean. A stage right before comma embryo. Also called lima embryo or lima bean stage. bean embryo Ce WBls:0000016
  The C. elegans life stage spanning 145-150 min after first cleavage at 20 Centigrade. Contains 88 cells. 88-cell embryo Ce WBls:0000012
