The phrase "are derived from normal" is correct and usable in written English.
It can be used in contexts discussing origins, sources, or foundations of concepts, processes, or phenomena that are considered standard or typical.
Example: "The results of the experiment are derived from normal statistical distributions, ensuring the validity of our findings."
Alternatives: "are based on standard" or "come from typical".
Because tumors are derived from normal cells, most of the TAAs identified are self-antigens, and such TAAs are usually differentially overexpressed in tumor cells and are also expressed at a low level in some normal cells.
Expression of one or two endothelial markers on tumor vascular endothelial cells does not seem to sufficiently prove that they are derived from normal progenitors.
The human cells used in this report are derived from normal subjects or patients diagnosed with CDG Ia (PMM2 mutations: p.Ile132Thr/p.Arg123Gln [26]), CDG Ie [27], CDG Ig [28] and CDG Ih [22].
RWPE1 cells are derived from normal prostate epithelia and do not express ERG.
The majority of the characterized melanoma-associated CTL epitopes are derived from normal, non-mutated proteins.
HMECs are derived from normal breast tissue removed from healthy women during breast reduction mammoplasty [ 14].
Several studies [ 19– 22] explored the effect of reconstruction settings on volume measurement variability, but they are derived from normal-dose chest CT, and no data are available from low-dose chest CT so far.
Furthermore, the AML-initiating cells appeared to be derived from normal hematopoietic stem cells directly linking stem cells to tumorigenic cells.
Other tissues were derived from normal individuals posthumously during autopsy after cardiac arrest.
Adult neurons were derived from normal temporal cortical samples removed during surgery for medial temporal lobe low grade glioma.
The CRC cell line LOVO showed modestly increased levels of SGK1 expression (3.7 to 6.2-fold), while the RIE-1 cell line, which was used as a control as it is derived from normal small intestinal cells of rat origin, showed a prominent increase in Sgk1 levels (average fold change = 21; t-test p-value = 1.2×10−5) as expected from previous reports (Fig. 1a).
