Example: "In order to complete the project successfully, we must identify any additional factors needed for implementation."
Alternatives: "extra elements required" or "further considerations necessary".
Furthermore, our detailed study of the splicing outcome of this acceptor-splice site mutation adds to the growing number of studies investigating complex splicing outcomes and determining additional factors needed for correct pre-mRNA splicing.
Since the cells in this state still have all options of growth and development, we expected that vegetative specific genes would be only slightly reduced and that additional factors needed to progress to the commitment point would also be expressed.
Possibly, the addition of the bulky EGFP-moiety (which is of similar size as the GTPase itself) interferes with the binding of additional factors needed for recruiting LC3 or for targeting vesicles to LC3 positive compartments, thereby trapping the vesicles at a step just prior to the recruitment of LC3.

Further previous research shows CAT simulations do not predict all the variation and therefore additional factors need to be included to improve accuracy.
Hence, additional factors need to be invoked to explain the male frequency observed in the base population used in this study.
Bone morphogenetic proteins (BMPs) and fibroblast growth factors have been shown to be involved in this process, however additional factors needs to be identified for the fate determination, especially at the early stage of cardiomyogenic development.
Apparently, additional factors need to be taken into account when predicting the size and members of the Plasmodium exportome as well as antigens at the surface of the infected erythrocyte.
Additional factors need to be considered when interpreting this study.
These additional factors need now to be taken into consideration when predicting the outcomes of BER.
