What's the difference between endogen and endogeny?
Endogen
Definition:
(n.) A plant which increases in size by internal growth and elongation at the summit, having the wood in the form of bundles or threads, irregularly distributed throughout the whole diameter, not forming annual layers, and with no distinct pith. The leaves of the endogens have, usually, parallel veins, their flowers are mostly in three, or some multiple of three, parts, and their embryos have but a single cotyledon, with the first leaves alternate. The endogens constitute one of the great primary classes of plants, and included all palms, true lilies, grasses, rushes, orchids, the banana, pineapple, etc. See Exogen.
Example Sentences:

(9) The hemodynamic effects of captopril and other angiotensin-converting enzyme inhibitors may be mediated by the endogenous opioid system.
(10) Although the brain AP50 is prominently phosphorylated by an endogenous protein kinase in isolated coated vesicle preparations, the neuronal AP50 was not detectably phosphorylated in intact cells as assessed by two-dimensional non-equilibrium pH gradient gel electrophoresis of labeled cells dissolved directly in SDS-containing buffers.
(11) Endogeneous satellite cells in skeletal muscle regenerating from bupivacaine damage were infected with an injected retrovirus containing the Escherichia coli beta-galactosidase gene under the promoter control of the Moloney murine leukemia virus long-terminal repeat.
(12) Moreover, the most recent combined application of the rat interstitial cell testosterone (RICT) bioassay and a novel multiple-parameter deonvolution model has allowed investigators to dissect plasma concentration profiles of bioactive LH into defined secretory bursts, which have numerically explicit amplitudes, locations in time, and durations, and are acted upon by determinable subject- and study-specific endogenous metabolic clearance rates.
(13) ACTH and dcAMP affect depletion of endogenously labeled ascorbic acid in IAC by a process that is both concentration- and time-dependent, but is independent of steroidogenic processes.

(15) The p30 proteins of murine viruses also contain a second discrete set of antigenic determinants related to those in infectious primate viruses and endogenous porcine viruses, but not detected in the feline leukemia virus group.
(16) For this purpose fragments of hypothalamus containing arcuate-periventricular nuclei and median eminence were incubated in vitro and endogenous DA released into the medium was assayed by radioenzymatic assay.
(17) To investigate endogenous cardiac glycoside-like compounds in plasma and their ability to inhibit the sodium pump, digoxin-like immunoreactivity [digoxin-like immunoreactive substance(s), DLIS] and 86Rb uptake by erythrocytes were measured in plasma extracts from normal adults, hypertensive adults and neonates.

(20) Because this transport system in the choroid plexus is normally responsible for the excretion of the serotonin metabolite from the brain to the plasma, accumulation of endogenously produced organic acids in the brain, secondary to reduced clearance by the choroid plexus, could be a contributing factor in the development of encephalopathy in children with medium-chain acyl-CoA dehydrogenase deficiency who have elevated levels of octanoic acid systematically.
Endogeny
Definition:
(n.) Growth from within; multiplication of cells by endogenous division, as in the development of one or more cells in the interior of a parent cell.
Example Sentences:
(1) Both parasites infect the blood and kidney, divide by endogeny, and are released by disintegration of the primary mother cell.
(2) During reproduction, which takes place by fission or more often by endogeny, the membranes of the daughter individuals are formed from the membranes of the parent.

(6) On the other hand we also observed, in the endogeny form of trophozoite, a thin GMS-positive layer in the parent pellicle though this pellicle showed no differences from those of daughter and common trophozoites when observed by means of ultrathin section microscopy.
