- excess seam cells
Animals execute supernumerary cell divisions during the development of the lateral, alae-producing epithelial cells, resulting in a larger number of these cells than control animals.
- fewer seam cells
The population of the lateral, alae-producing epithelial cells (seam cells) is reduced compared to control animals.
- seam cells stacked
The hypodermal cells, which lie along the lateral body wall to form longitudinal stripes of epithelial cells underlying the alae, are misplaced such that they are stacked along the dorsal-ventral axis rather than forming a continuous row of adjacent cells .
- seam cell morphology variant
Animals exhibit variations in the structure, organization or placement of the population of the lateral, alae-producing epithelial cells (seam cells), compared to that observed in control animals.
- precocious seam cell fusion
Seam cells fuse to form a continuous syncytium along the body wall at an earlier stage of development compared to control.
- retarded seam cell fusion
Seam cells fuse to form a continuous syncytium along the body wall at a later stage of development compared to control.
- seam cell fusion variant
Variations in the ability of seam cells to fuse to form a continuous syncytium along the body wall late larval development, (separate from the hyp 7 syncytium), compared to control (WormAtlas). Hypodermal seam cells lie along the lateral body wall to form longitudinal stripes of epithelial cells underlying the alae, and are required for alae formation.
- alae secretion variant
Variations in the regulated release of proteins needed for alae formation by epidermal seam cells compared to control. Alae are small linear ridges running along the lateral lines of the cuticle, lengthwise along the body (WormAtlas).
- long range axon migration variant
Animals exhibit axons with migration behaviors that differ from those observed in control animals after the axons cross a half-way point between opposing neural cords. In C. elegans this point is marked by the lateral seam cells between the ventral and dorsal cords.
- short range axon migration variant
Animals exhibit axons with migration behaviors that differ from those observed in control animals before the axons reach a half-way point between opposing neural cords. In C. elegans this point is marked by the lateral seam cells between the ventral and dorsal cords.
