The phrase "maintain expression of" is a correct and usable structure in written English.
It is often used in contexts related to communication and language, specifically in discussing the act of expressing oneself or maintaining a certain tone or style. Here is an example of how it could be used: "He studied different techniques to maintain expression of his ideas in a clear and concise manner." In this sentence, the phrase is used to describe the actions of the subject in ensuring that his ideas are effectively communicated.
Adult SCs maintain expression of OCT4, and because CSCs express this gene, this suggests tumor cells are derived from normal SCs (Tai et al. 2005).
Mase et al. found that many miRNAs in the let-7 family are expressed in human ovarian granulosa KGN cells, which maintain expression of FSH receptors.
Undifferentiated 5T4-GFP ES cells lack EGFP and maintain expression of the pluripotent markers OCT-4 and NANOG.
TCR-transduced PBMC also secrete IFN-γ upon coculture with LMP2 targets and maintain expression of the transduced TCR during subsequent mitogenic expansion.
These results suggest that in normal sex determination, zebrafish oocytes passing through meiosis signal the gonadal soma to maintain expression of aromatase, an enzyme that converts androgen to estrogen, thereby feminizing the gonad and the individual.
These data suggest that cultured PGCs are immortalized cells that maintain expression of both surface markers and PGC-specific genes.
Importantly, cassette inversion maintains physiologic transcript structure, thereby ensuring proper microRNA-mediated regulation of the GFP reporter, as well as maintaining expression of nonprotein-coding elements.
Aged wild type tendons maintained expression of decorin which was associated with the structural and functional changes seen in aged tendons.
A typical postarterial capillary stretch would be positive for Cldn5 but gradually lose Cldn5 immunostaining in subsequent segments, while maintaining expression of the vascular marker Isolectin B4 (Fig. 2e; quantification in Fig. 2f).
These genes were also induced in macrophages infected with live C. albicans (clusters 1 and 2; Fig. 2d), indicating that maintaining expression of these genes may be important for pathogen clearance and host cell survival after phagocytosis.
In addition, they maintained expression of CD105, CD73, and CD90.
