We identify a population of mesodermal cells in a developing invertebrate, the marine annelid Platynereis dumerilii, that converges and extends toward the midline and expresses a notochord - specific combination of genes. (scienceintheclassroom.org)
These comparative data suggest that a similar population of mesodermal midline cells already existed in urbilaterian ancestors but leave open its ancient developmental fate. (scienceintheclassroom.org)
We differentiated our iPS cells as embryoid bodies (EB)(Figure 4A) in the presence of FBS to induce endodermal and mesodermal fates, and in the presence of retinoic acid to induce an ectodermal fate, and after ten days allowed them to adhere to tissue culture dishes. (journals.plos.org)
