Neoplastic clone
WebInfrequently, divergent differentiation of a single neoplastic clone along two lineagescreates what are called mixed tumors. The best example of this is the mixed tumor of salivary gland origin.. These tumors contain epithelial components scattered within a myxoid stroma that sometimes contains islands of cartilage or bone. All these elements, it is believed, arise … WebOct 11, 2015 · Inflammation has a central role in myeloproliferative neoplasm (MPN). Excessive inflammation not only causes many of the debilitating symptoms associated with the disease but also drives the selective expansion of the neoplastic clone [ 1 – 3 ]. Inflammation may also be directly responsible for some pathologic features of the …

WebJun 4, 2024 · The regions of the BMZ beneath growing clones of pre-neoplastic cells are of considerable interest because these are the regions where the BM becomes eroded on tumor invasion. In the larval cancer models, as pre-neoplastic clone diameter increases to 30–50 μm, individual holes beneath them begin to coalesce (Figure 4 D). WebOct 31, 2024 · Even in the early stages of the disease, patients have circulating neoplastic T-cell clones in peripheral blood. Early lesions are initiated by the pioneer clones and create a niche (blue-shaded area) that facilitates seeding of this area of the skin (lesion 1) with subsequent clones (lesion 2) (consecutive seeding model 43 and supplemental ...
