The phrase "are needed for embryonic" is correct and usable in written English.
It can be used in contexts discussing biological processes, development, or requirements for embryonic growth or formation.
Example: "Certain nutrients and factors are needed for embryonic development to occur successfully."
Alternatives: "are essential for embryonic" or "are required for embryonic".
The first is that the new international institutions are necessary appendages to police the global rules that most people agree are needed for the proper functioning of our embryonic international order.
De Almeida et al. [ 23] described the procambial cells as niches of pluripotent and totipotent stem-like cells for organogenesis and somatic embryogenesis, and Hutchison et al. [ 11] proposed that the maturation-related decline of adventitious root formation could result from the suppression of gene expression levels that are needed for adult cells to re-enter the embryonic root formation pathway.
There are hints that reverse transcriptase is needed for a lot of early embryonic functions associated with getting cells ready to specialise into different types of tissue.
To determine whether a mammalian cellular environment is needed for expression of active GLTPi paralog, human embryonic kidney cells (HEK 293T) were transfected with FLAG-CMV vector containing the GLTPi and GLTP ORFs.
Similar to its role in embryonic muscle, CF2 in the IFM may be needed for the fine-tuning of structural gene expression.
Vtg is an essential component needed for embryonic development.
"So for example, if you take a mammary gland nucleus from a cow, the genes needed for milk production are active, but not the genes needed for embryonic development.
Other scientists say more evidence is needed to verify whether embryonic stem-like cells were created.
So, although angiogenesis is a process which is needed by the host for wound healing, embryonic development and development of the corpus luteum, it is now possible to selectively target these differences and create drugs which would satisfactorily counter the tumorigenic state without affecting the functions of the host's preexisting or normally functioning vasculature.
Identification of receptor mediated signaling pathways in embryonic stem (ES) cells is needed to facilitate strategies for cell replacement using ES cells.
