- Similar results have been reported recently from genome-wide sperm, other oocyte and embryo methylome studies., In contrast to the exceptionally restricted potential of germ cells, the zygote is the only truly totipotent entity in mammals.
It is suggested that the band-edges of the semiconductor are pinned only for a restricted potential range, depending on the ad hoc experimental conditions.
Another clonal pulp cell line, H8, is a monopotent progenitor that displays a restricted potential of differentiation towards the odontoblastic fate (Lacerda-Pinheiro et al. 2012).
A high throughput-screening approach was used to test thousands of combinations of bioactive molecules (i.e., molecules that are known to affect living cells in different ways) to identify some that could promote the self-renewal of cells with a restricted potential to differentiate.
Specifically expressed in INPs, a Zinc-finger transcription factor Earmuff (Erm) plays a critical role in maintaining the restricted developmental potential of the INPs (Weng et al., 2010).
The negative characteristics of sea/lake-based mesocosms compared to land and indoor facilities are their sensitivity to weather conditions and very restricted potential to control light, temperature and turbulent mixing, whereas the ability to adjust nutrients, pH and food-web structure is approximately the same as for the land-based and indoor counterparts.
This, however, does not appear to be the norm in regeneration-competent vertebrates, which are characterized by progenitors with restricted potential (For a review see ref. 22).
In addition, stem cells with a more restricted potential have been characterized from post-embryonic tissue types.
CFU-G and CFU-M represent more committed progenitor cells with a more restricted potential to differentiate.
This allowed us to construct half-embryo chimeras from two four-cell blastomeres (i.e., two animal-vegetal [AV] parts [AV-AV]) that were previously shown to have full developmental potential (Piotrowska-Nitsche et al., 2005; see Experimental Procedures and legend to Figure 2B), and half-embryo chimeras from blastomeres of restricted potential (two vegetal blastomeres [V-V]).
