Standard Temperature: 20 degree C
proliferating embryo (=early) 0-350min Until cleavage is over elongating embryo (=mid) 350-620min During elongation fully_elongated embryo(=late =pre-hatched = morphogenetic) 620-800min After elongation
pre_gastrula embryo 0-100min Until gastrulation starts gastrulating embryo 100-290min During gastrulation enclosing embryo 290-350min (proposed) late cleavage stage embryo 210-350min At least 200 cells, not elongated yet bean embryo 350-390min Elongation started, but not comma yet comma embryo 390-420min According to Sulston figure 1.5-fold embryo 420-460min According to Sulston figure 2-fold emrbyo 460-520min According to Sulston figure 3-fold embryo (=pretzel) 520-620min According to Sulston figure, and M. Labouesse 1-cell embryo -50 - 0 min Included in pre-gastrulation embryo 2-cell embryo 0-20min Included in pre-gastrulation embryo 4-cell embryo 20-40min Included in pre-gastrulation embryo
(.. other -cell embryos) --- (proposed) 51-cell embryo 120-135min Will replace the original "50-70 cell embryo" 88-cell embryo 145-150min Will replace the original "90 cell embryo"

Explanations on WormBase Life_stages:
We are going to have 3 threads to describe embryonic Life_stages. Each of these threads will cover the whole embryonic life stages from 0min to 800min. The order they are listed are their time-order. Example: "proliferating" is followed by "elongating", then by "fully-elongated".
Thread A: proliferating/elongating/fully-elongated Thread B: pre-gastrulation/gastrulating/.../3-fold/fully-elongated Thread C: 1-cell/2-cell/.../51-cell/.../88-cell/...
See the color code listed above for the status of each Life-stage.
