What's the difference between cytogenesis and cytogeny?
Cytogenesis
Definition:
(n.) Development of cells in animal and vegetable organisms. See Gemmation, Budding, Karyokinesis; also Cell development, under Cell.
Example Sentences:
(1) At about E31, the last day of gestation, the laminar structure of the retina begins to mature, cytogenesis begins to cease and the outer plexiform layer starts to form.
(2) A detailed consideration of their shared and differing cytological features suggests that the various blood cells represent different stages of cytogenesis along a common or single path of cellular differentiation.
(3) While current views of the incidence, histology, and cytogenesis are presented, the main purpose of this article is to call attention to the identifying clinical and radiological characteristics of these spinal tumors.
(4) Prior applications of BUdR for studies of cytogenesis in the CNS have been extended in two principal ways: (1) basic fuchsin was used as counterstain for BUdR-negative nuclei and (2) labelling indices were determined separately in strata or bins, 10 microns in height, through the full depth of the ventricular zone and overlying cerebral wall.
(5) The mechanism underlying cytogenesis in the adrenal cortex of ACTH-treated rats was investigated.
(6) They may be associated with the neck stem cells in the cytogenesis of gastric adenomas.
(7) The Type C cytogenesis of Aschoff cells takes place through direct transformation of cardiac muscle fibers which show central hyalinization of myoplasm and changes in nuclei from normal to single or multinucleated large vesicular forms.
(8) These findings may support the theory of the combination tumor as the cytogenesis of mixed mesodermal tumor of the ovary; they also suggest the conversion of carcinomatous cells to sarcomatous cells.
(9) Cytogenesis ceases in this layer after the first postnatal week.
(10) This heterogeneity of the histochemical properties of tumour cells is discussed with regard to the role of the stem (polypotent) cell in the process of the histogenesis (cytogenesis) of human gastric carcinomas.
(11) At the ages studied, the progeny of Stage 1 cytogenesis are distributed in an annulus toward the margin of the retina, and those of Stage 2 occur central to the annulus, indicating that Stage 2 follows Stage 1.
(12) The cytogenesis of the perineurium remains disputable, with morphologic, immunohistochemical, and experimental evidence supporting origin from the fibroblast, Schwann cell, and arachnoid cap cell.
(13) The results support the migration hypothesis of adrenocortical cytogenesis.
(14) Although the cytogenesis of null cell adenomas and oncocytomas is not clear, it can be suggested that these two tumor types are derived from a pluripotential precursor cell that is capable of undergoing multidirectional differentiation and synthesizing various hormones, mainly glycoproteins.
(15) Developmental events beginning here include the formation of cell-free channels at the vitreal margin; the appearance of the first ganglion cells and their axons; the formation of continuous inner and outer plexiform layers; the differentiation of cells in the ganglion cell, inner, and outer nuclear layers; and the cessation of cytogenesis at the outer limiting membrane.
(16) The cytomorphology and cytogenesis of BK virus-transformed hamster brain cells (HBBK cells) were studied.
(17) The demonstration of a well-characterized, cell type-specific marker in a tumor reflects not so much its cytogenesis as its differentiation potential and its capacity for metaplasia.
(18) Until the cytogenesis of PTC is clarified we propose the noncommitted term "plasmacytoid T-zone cells" for this elusive cell type.
(19) Following hypotheses have been postulated on the cytogenesis of intramedullary schwannoma in the literature: Central displacement of Schwann cells during embryonic development.
(20) The noradrenergic (NA) innervation of the rat hippocampal formation arrives embryonically into a structure in which cytogenesis and cell migration are still active processes.
Cytogeny
Definition:
(n .) Cell production or development; cytogenesis.
Example Sentences:
(1) Receptors for testosterone (T) and dihydrotestosterone (DHT) as well as the tissue specific androgen-5 alpha-reductase (A5R) were studied in the foreskin of 52 healthy boys (ages 1-14 years), in order to gain molecular endocrinological data and information about the ontogeny and cytogeny, respectively, of androgen specific target organs.
