Discovered on gastrointestinal stromal tumor 1 (DOG1) is expressed in pancreatic centroacinar cells and in solid-pseudopapillary neoplasms: novel evidence for a histogenetic
1,9,12] This was a major area where morphology was invariably supplemented by IHC for establishing the histogenetic
origin/expression, since a variety of soft tissue sarcomas share common microscopic patterns.
Analysis by comparative genomic hybridization of epithelial and spindle cell components in sarcomatoid carcinoma and carcinosarcoma: histogenetic
Dissociated expression of Bcl-2 and Ki-67 in endometrial lesions: diagnostic and histogenetic
4,5 The diagnostic approach to space - occupying lesions in the liver can be difficult and a histogenetic
classification of the primary tumour is impossible in some cases.
7), (8) Meyer (1920) classified carcinosarcomas into three histogenetic
groups: 1) collision tumors in which carcinoma and sarcoma arise simultaneously in proximity and subsequently invade each other, 2) combination tumors in which both tumors derive from pluripotent cells, and 3) composition tumors in which the components arise from the same tissue.
2-9) Associated with nosologic, histogenetic
and aetiopathogenetic controversy, IMFTs occur in all age groups and in diverse body sites, with no definite gender bias.
One of the most basic techniques, which can be tried to tentatively explore the histogenetic
relation-ships in the gut wall epithelia, is the label-retaining cell (LRC) approach.

processes, Cerebellum, 1: 137-142.
Retinogenesis proceeds in two distinct yet overlapping histogenetic
periods, characterized by the development of early-born cells (ganglion, horizontal, cone, and amacrine cells) mostly during embryogenesis and late-born cells [rods, bipolar cells (BCs), and MGCs] during early postnatal development (Livesey and Cepko 2001; Martins and Pearson 2008; Young 1985b).
8) A close histogenetic
relationship exists between the central cemento-ossifying fibroma and the central ossifying fibroma.
Differential expression, of BCL-6, CD138/syndecan-1, and Epstein-Barr virus-encoded latent membrane protein-1 identifies distinct histogenetic
subsets of acquired immunodeficiency synd tome- related non-Hodgkins lymphomas.
