The phrase "are essential for stem" is not correct as it is incomplete and lacks context.
It could be used in a sentence discussing the importance of certain elements or factors for a specific subject related to "stem," such as STEM education or STEM fields.
Example: "The resources and support provided by the school are essential for stem development in students."
Alternatives: "are crucial for STEM" or "are vital for STEM".
The recent observation that adhesion molecules are not only important determinants for the molecular, but also mechanically guided lineage selection and differentiation of stem cells [55] adds to the concept that adhesion molecules are essential for stem cell biology.
Non-coding RNAs (ncRNAs) are a class of molecular species that, for example, play regulatory roles, have been implicated in human diseases, and are essential for stem cells [1], [2], [3], [4], [5].
This list may contain a core set of genes that are essential for stem cell proliferation and maintenance.
H2Bub1 resolves the bivalency state of numerous genes, which are essential for stem cell progeny differentiation in multiple systems (Johnsen, 2012).
TICs are also characterized by transcription factors that are essential for stem cell self-renewal and pluripotency, and which include Nanog and Oct-4A [ 10, 11, 22].
Interestingly, DNA methylation at genes that are essential for stem cell renewal are primarily associated with coding sequences, not gene promoters.
However it is presently unclear to what extent telomere length maintenance via TERT is essential for stem cell activation.
In addition, recent evidences have shown that NHEJ repair activity, among others DNA repair pathways, is essential for stem cell maintenance, and a decline in DNA repair function with age is observed [54].
The stem cell niche is essential for stem cell functions.
NS is essential for stem- and cancer-cell proliferation [ 4].
The AtWOX5 protein is essential for stem cell maintenance via a negative feedback signal provided by CLE40 [ 11].
