pa·ren·chy·ma

(pə-rĕng′kə-mə)
The basic tissue of plants, consisting of thin-walled, nonspecialized cells that sometimes adapt to specialized functions. The internal layers of leaves, the cortex and pith of the stem, and the soft parts of fruits are made of parenchyma. In higher plants, parenchyma supports the plant body, roots, and leaves; it also stores water and contains chloroplasts in which photosynthesis takes place.

One of the consequences is accumulation of iron in the parenchymal cells of liver which cause toxicity.
The level of estradiol in breast-cancer tissue is roughly 10 times the concentration present in the plasma in the postmenopausal women, perhaps because of the presence of intratumor aromatase both in the stroma and parenchymal cells of the carcinomatous tissue17.

He believed that oncocytes were the result of a degenerative phenomenon in salivary gland parenchymal cells. Zimmermann observed the presence of oncocytes in the sublingual gland and referred to these cells as "pyknocytes" alluding to their condensed nuclear chromatin or pyknotic nuclei [1].
Activated innate immune cells release abundant inflammatory cytokines (e.g., tumor necrosis factor and interleukins) that initiate inflammatory and also cell death signaling cascades in immune cells and parenchymal cells [2].
