What's the difference between organogenesis and organogeny?
Organogenesis
Definition:
(n.) The origin and development of organs in animals and plants.
(n.) The germ history of the organs and systems of organs, -- a branch of morphogeny.
Example Sentences:

(4) Further research is necessary to investigate possible teratogenic effects that might occur if the spirochete reaches the fetus during the period of organogenesis.
(5) In the present study the distribution of various sugar residues in the cells of the male gonad during postnatal organogenesis was examined employing eight lectin-horseradish peroxidase conjugates (BS-I, ConA, DBA, PNA, RCA-I, SBA, UEA-I, WGA) on paraffin-embedded testicular tissue.
(6) Renal dysplasia was associated with extrarenal malformations in 2 of our cases and we therefore believe that the significance of the dysplasia lies rather in the period of the insult during organogenesis than in the obstruction.
(7) In the present study we investigated (1) the developmental pattern of expression of the chicken insulin gene in the pancreas; (2) the expression of the insulin gene in three nonpancreatic tissues, liver, brain, and lower limb, during chicken development; and (3) the expression of the insulin gene at prepancreatic stages and during chicken embryo organogenesis.
(8) However, the stress associated with maternally toxic doses can be expected to result in associated, often transient, fetal abnormalities that may not be the result of deviant organogenesis.
(9) Insulin and insulin-like growth factor I (IGF I) play an important part in these events in the later stages of embryogenesis, when organogenesis is completed.
(10) We briefly review evidence from in vitro models that supports a role for the extracellular matrix in two essential steps of organogenesis: the establishment of appropriate three-dimensional cell-to-cell relationships, and the determination of a correct cell polarity.
(11) The experiments indicate that D-mannose may be employed in model systems with rodents for precisely timed interruptions of organogenesis in vivo.
(12) Estradiol-17 beta (E2) and 17 alpha-ethinyl estradiol-17 beta (EE) were compared in terms of their relative capacities to alter growth and developmental patterns of cultured whole embryos during the early stages of organogenesis.
(13) However, we established an enhanced level of [14C]acetate incorporation at the time of extensive gene activation during gastrulation as well as some quantitative differences in the pattern of acetylation during gastrula and organogenesis.
(14) It describes the entire gestation period including the period of organogenesis.
(15) Lysosomes participate in the following processes during the course of embryonal organogenesis: 1. destruction of cells of transient embryonal organs; 2. destruction and demolition of whole cells during the course of normal embryonal development; covering with a membrane and lysis of inferior cellular organelles; 5. lysis with consecutive assimilation of cytoplasmic inclusion; lysis of secretory products.
(16) The expression of vimentin, cytokeratins (CKs) and neurofilament (NF) proteins was analysed (using monoclonal antibodies) in the mouse inner ear at the otocyst stage (13th gestational day), when organogenesis was largely completed (16th gestational day) and at birth (21st gestational day).
(17) We conclude: 1) ANP is present in the fetus shortly after the completion of organogenesis; 2) 16 K ANP is the principal intracardiac species in the fetus and the adult; and 3) the existence of ANP soon after cardiac development suggests a possible role for ANP in fetal blood pressure and sodium and water homeostasis.
(18) Morphogenesis was retarded during the early organogenesis stages, but only a slight delay was seen in the treated embryo on day 12.
(19) Congenital rubella syndrome occurred in 2 newborn infected at the organogenesis period (4-8 weeks).
(20) We have used monoclonal antibodies to study the changes in the expression of four kidney antigens during organogenesis in the sheep.
Organogeny
Definition:
(n.) Organogenesis.
Example Sentences:
(1) Six stages in development are distinguished: the 'lung form' (stage 1), attaining maximum numbers on day 5 post-infection; the 'closed-gut form' (stage 2) on day 14, characterized by the union of the gut caeca behind the ventral sucker; 'organogeny' (stage 3) on day 17, the male possessing one testis and a gynaecophoric canal and the female a narrow uterus; 'gametogeny' (stage 4) on day 26, with pairing, the male having four fully developed testes and the female an ovary; 'egg-shell formation' (stage 5) on day 35; 'oviposition' (stage 6) on day 37, with the female showing uterine eggs.
(2) DNA content increased greatly during cleavage, gastrulation, and organogeny and RNA increased during cleavage and blastula formation.
(3) In vivo development of Echinostoma malayanum Leiper, 1911 was studied in white rats and the developmental process was arbitrarily divided into four stages: organogeny, vitellogenesis, formation of Mehlis' gland complex and cirrus sac, and oviposition.
(4) The process of maturation was divided for convenience into six stages: Stage 1; cell multiplication, Stage 2; body shaping, Stage 3; separation of genital anlagen, Stage 4; organogeny, Stage 5; gametogony, and Stage 6; oviposition.
(5) In stage 3 'Organogeny' (day 24) males developed one testis and females a narrow uterus.
(6) Just on the contrary, in mucous and signet-ring cell carcinomas the picture of an advanced cell differentiation was observed in a complete loss of organogeny.
