Following statements are regarding to the early development in nematodes. Which of the following is incorrect?

#Unit 5. Developmental Biology
  1. At the 4-cell stage, the EMS cell requires a signal from its neighbor (and sister cell), the P2 blastomere. Usually, the EMS cell divides into an MS cell (which produces mesodermal muscles) and an E cell (which produces the intestinal endoderm).
  2. If the P2 cell is removed at the early 4-cell stage, the EMS cell will divide into two E cells, and endoderm will be produced.
  3. If the EMS cell is recombined with the P2 blastomere, however, it will form endoderm; it will not do so, however, when combined with ABa, ABp, or both AB derivatives.
  4. Specification of the MS cell begins with maternal SKN-1 activating the genes encoding transcription factors such as MED-1 and MED-2.
