RNA recognition by the embryonic cell fatedeterminant and germline totipotency factor MEX-3
Renewal of totipotent stem cells in the germline and cellular differentiation during early embryogenesis rely upon posttranscriptional regulatory mechanisms.
However,the nucleotide sequence specificity and requirements of MEX-3 mRNA recognition remain unclear.
Only a few candidate regulatory targets have been identified,and the full extent of the network of MEX-3 targets is not known.
Here,we define the consensus sequence required for MEX-3 RNA recognition and demonstrate that this element is required for MEX-3 dependent regulation of gene expression in live worms.
Based on this work,we identify several candidate MEX-3 targets that help explain its dual role in regulating germline stem cell totipotency and embryonic cell fate specification.

滋养层细胞属于胚胎干细胞么?
RT——胚胎干细胞（embryonic stem cell,ESCs,简称ES或EK细胞.）胚胎干细胞是早期胚胎（原肠胚期之前）或原始性腺中分离出来的一类细胞.那么滋养层细胞属于囊胚期的早期胚胎细胞,是胚胎干细胞么?
