"requires further confirmation" is a perfectly correct and usable phrase in written English.
It is usually used to indicate that additional verification is necessary in order to prove the truth or accuracy of a statement. For example, "John's claim that he won the lottery requires further confirmation."
Although this model requires further confirmation, critical contributions of the transmembrane span in signaling are also confirmed by the fact that chimera of the ECDs of HER3 and the cytoplasmic domains of HER2 are only functional when connected through the stronger self-associating transmembrane span of HER2 [ 11] but not with the corresponding segment of HER3 [ 41].
There is some evidence that individuals or populations of subspecies littorale are subject to seasonal elevational movements, but this requires further confirmation.
However, Src and Abl are, like mTOR and AKT, broadly connected to signaling pathways for many cellular functions, and whether Src, ErbB2/3, mTOR, AKT, and PI3Kγ actually form a mechanistic network in U87 mg electrotaxis requires further confirmation.
Also field performance requires further confirmation on different soils.
This is an area that requires further confirmation.
Therefore our finding requires further confirmation.
This hypothesis thus requires further confirmation once such pathways have been identified.
Also, the effect seems apparent only after the first few days (day 3 post TST) and potentially wanes after 3 months, but this requires further confirmation.
Qualitative analysis of the spatio-temporal targeting of glioma by NSCs in MRI requires further confirmation that the detected MRI signal arose from FE-Pro-labeled NSCs.
An alternative proposal for the formation and maintenance of isochores, which states that "biased gene conversion (BGC) is probably the most likely cause of isochores" [7], is probably more reasonable but requires further confirmation.
This finding requires further confirmation.
