What's the difference between excrescency and outgrowth?
Excrescency
Definition:
(n.) Excrescence.
Example Sentences:

(14) The sympathetic trunk itself (ganglia and cord) was affected only by osteophytes of vertebrae at the lowest thoracic levels; however, bony excrescences due to costovertebral joint arthritis were frequently found impinging on the sympathetic trunk and its rami communicantes at similar frequencies on both sides.
(15) Membrane-delimited vacuoles, lipid droplets and cytoplasmic excrescences appeared in myelinating Schwann cells at 24 hr; demyelinating axons appeared at 48 hr of tellurium exposure.
(16) Mossy fiber endings were identified by their large size and their numerous clear synaptic vesicles with some dense-core vesicles intermingled, and were observed to form synaptic contacts on the large spines or excrescences.
(17) One category, termed short-shaft pyramidal neurons, is characterized by short apical shafts, a large number of thorny excrescences, and densely branched apical and basilar trees.
(18) A calcific eyelid excrescence removed from the patient, studied by x-ray diffraction, was found to consist of crystals of hydroxyapatite.
(19) Comparison with phase contrast light microscopy shows that the fine excrescencies cannot be resolved and therefore lead "artificially" to a more confined aspect of the nucleoid.
(20) A few small excrescences are present on the proximal dendrites.
Outgrowth
Definition:
(n.) That which grows out of, or proceeds from, anything; an excrescence; an offshoot; hence, a result or consequence.
Example Sentences:
(1) Dibutyryl cyclic AMP (dbcAMP) treatment of Neuro 2A neuroblastoma cells induces cell differentiation and neurite outgrowth.
(2) Histochemical and immunocytochemical staining of the outgrowths with reagents that depict epithelial, myoepithelial, and lactating alveolar cells (peanut lectin alone, monoclonal and polyclonal antibodies to rat caseins) indicate similar cell compositions and arrangements for all outgrowths irrespective of their source; these are also similar to the mammary glands of the perphenazine-stimulated or lactating hosts.
(3) This study demonstrates that a second classical neurotransmitter, dopamine, can act to suppress regenerative neurite outgrowth.
(4) Salt concentrations slightly lower than those providing inhibition tended to extend spore outgrowth time at low temperatures.
(5) Urban ambulance systems emerged in the second half of the 19th century as an outgrowth of military experiences in both Europe and America.
(6) Adhesion to a substrate results in outgrowth of the cells and monolayer formation, even when extensive cell damage had occurred.
(7) These results suggest that purified laminin can facilitate and guide process outgrowth of 5-HT, DA and NE neurons during early developmental stage, but does not induce sprouting on these same fiber types in the adult brain.
(8) These data suggest that the induction of tau and MAP1 in response to NGF promotes microtubule assembly and that these factors are therefore key regulators of neurite outgrowth.
(9) However, whereas a critical value of N-CAM expression is required for increased neurite outgrowth, with small increases above this value having substantial effects, N-cadherin promotes neurite outgrowth in a highly linear manner.
(10) Outgrowth of neurites from neuronal cells was promoted by precoating the metal surface with either laminin or neurite promotion factor.
(11) Previous work from our laboratory had shown that goldfish retinal fragments explanted onto a polylysine substratum 1 to 2 weeks following optic nerve crush exhibit a striking clockwise pattern of neuritic outgrowth.
(12) The 33 kDa C-terminal cell and heparin-binding fragment of FN, in particular, is a strong promoter of CNS neurite outgrowth.
(13) Spontaneous outgrowth of immortalized Epstein-Barr virus (EBV) infected B-cell clones will occur from cultures of peripheral blood mononuclear cells (PBMNCs) of some persons with a history of EBV infection.
(14) The time of axonal outgrowth and the location of the cells in the developing embryo were determined by filling RS neurons retrogradely with horseradish peroxidase from their growing axons over a series of developmental stages.
(15) We have, therefore, developed a tool that allows us to measure microtubule polymerization equilibria out the neurites of cells in culture, which will allow us to test hypotheses that factors which affect neurite outgrowth do so by means of effects on microtubule polymerization equilibria.
(16) Molecular characterization of such genes could lead to the identification of molecules critical in axonal outgrowth and guidance in higher organisms.
(17) Recombinant F-spondin promotes the attachment of spinal cord and sensory neuron cells and the outgrowth of neurites in vitro.
