The specific function of ERK2 in the initiation, maintenance and patterning of mesoderm and endoderm formation was biologically confirmed.
It has been suggested that the intersection or combination of the PLT and the SHR/ SCR pathways is both necessary and sufficient for the localization, maintenance and patterning of the root SCN [ 11].
The outcomes of the predictions for ERK2 knockdown on developmental signaling were confirmed by in situ hybridization experiments indicating that ERK2 controls mesoderm and endoderm initiation, maintenance and patterning.
Interestingly, examining the experimental evidence of SC GRNs in other organisms suggests that this motif could be a generic regulatory motif for systems underlying SCN maintenance and patterning throughout multicellular eukaryotes [ 34, 48, 92, 93].
This blastocoel floor derived tissue could be regarded as a direct inducer of the anterior neuroectoderm, although it is well known that various signals emanating from a variety of tissues are necessary for the maintenance and patterning of the anterior neural tissues during development.
Maintenance and discard patterns are a central aspect of projectile point analyses.
Unfortunately, while the examination of maintenance and discard patterns for lithic technologies is well advanced, osseous projectile point maintenance and discard analyses remain in their infancy.
POU5F1 and POU2 are the two principle members constituting the class V POU domain family of transcription factors, thought to have a conserved role in the regulation of pluripotency in vertebrates as well as germ cell maintenance and neural patterning.
The first wave of zygotic activation is enriched for genes involved in regulation of transcription, stem cell maintenance and axis patterning and development, whereas the second wave of zygotic activation is enriched for genes involved in control of translation, and the early signs of organogenesis, in heart and kidney development.
We found that Smed-ima-2 is required for general stem cell survival, while Smed-ima-1 is important for stem cell maintenance, differentiation, and patterning of regenerating tissues.
