Expression Pattern :

Pattern  During larval development, xnp-1::GFP is expressed predominantly in neurons. However, strong expression was reproducibly observed in the junctional cells of the spermatheca and uterus. In addition,variable and weaker expression was detected in other cells of the somatic gonad, such as the DTC, and in what appeared to be the thin outline of sheath cells surrounding the gonad. xnp-1::GFP is expressed in most cells during embryonic development, beginning at around the 100- to 200-cell stage of embryogenesis. xnp-1::GFP expression was reproducibly absent or greatly reduced in the intestinal cell lineages, suggesting that xnp-1 expression is not ubiquitous. Strong expression of xnp-1::GFP becomes restricted during late stages of embryogenesis, with highest levels of expression occurring in neuronal cells of the head, ventral nerve cord, and tail.
