Epithelial tissues are formed by organized, differentiated and mostly quiescent epithelial cells, which together produce the biological activity of epithelium.
Hence, the list of gene-probes from the TFA when d = 1 is less likely to contain DEGs originating from stromal tissue than when d = 0.2, because samples that consisted of mostly tumor epithelial cells counted more in the TFA when d = 1.
IL-32 is expressed in inflammatory and infectious diseases as well as in healthy tissue, mostly in epithelial cells [ 7- 9].
Three connexin genes are expressed in the vertebrate lens; α1 (connexinnnexin that is expressed mostly in epithelial cells [ 5]; α3 (Cx46) and α8 (connexinsnexins which are expressed in fiber cells [ 6, 7].
However, the number of CD44 variants (CD44v) identified so far is limited to a few dozen (Fig. 1), detected mostly on epithelial cells, keratinocytes, activated leukocytes and many types of tumor cell [ 2].
We cultured postmenopausal women's breast tissues containing mostly undifferentiated epithelial cells, which have a high capacity to proliferate by influence of various endogenous and exogenous stimuli such as steroid hormones.
Taken together, it seems that in vitro the postmenopausal breast tissues possess mostly undifferentiated epithelial cells [ 39], which respond to exogenous stimulus produced E2 but also progestin and their combination treatment with a proliferative response and decreased number of ER and PR positive cells.
The tadpole intestine remodels drastically, transforming from a simple tubular organ of mostly larval epithelial cells with little connective tissue or muscles, to a complex organ with a multiply folded adult epithelium supported by thick layers of connective tissue and muscles [ 11].
This lectin is mostly expressed in epithelial cells of the intestinal tract and secreted to the extracellular.
Proestrus consisted of mostly nucleated basal epithelial cells.
