Germ cells and somatic cells were discriminated by their differential expression of vimentin [12] (vimentin is only expressed by somatic cells).
As previously obtained with the untreated plastic support, immunocytochemistry analyses showed that albumin protein was only expressed by the differentiated cells after 14 days and no AFP expression was detectable in the differentiated or in control cells.
The MHC-II metagene is only expressed by antigen-presenting cells but not in T cells, while high expression of the MHC-I metagene is observed in all cell types as expected.
But to answer your original question, I would say that there are certain things what can be only expressed by means of a sentence.
Unique antigens are abnormal proteins that are only expressed by tumor cells.
E-selectin (CD62E), or endothelial-leucocyte adhesion molecule-1 (ELAM-1), is only expressed by endothelial cells after cytokine stimulation.
Note that all macrophages express CD68, while CD163 is only expressed by M2 (pro-tumor macrophages) [26, 27].
For instance, water regulation was only mentioned by civil and public sector respondents, while genetic resource preservation was only expressed by the private sector.
Furthermore, NELL2 is differentially regulated in the CNS and PNS; in the CNS, NELL2 is only expressed by nascent, post-mitotic neurons as they commence their differentiation, yet in the PNS, NELL2 is expressed by subsets of progenitor cells in addition to nascent neurons.
The issue isn't only expressed by its parliamentary members but also among its supporters, particularly the young.
