What's the difference between blastogenesis and budding?
Blastogenesis

(15) To determine whether the polyclonal immunomodulator, Phytohemagglutinin (PHA), stimulates murine lymphocytes in vivo and causes cytotoxic differentiation, we studied blastogenesis and the concomitant synthesis of macromolecules (DNA, RNA and protein) by lymphocytes at different hours after injection of PHA in mice.
(16) Use of Toxocara exoantigens in the blastogenesis assay revealed that Toxocara exoantigens could elicit between 20 and 95% of the ConA response in BAL cells, while in spleen cells Toxocara exoantigens could only elicit 1 to 5% of the ConA response.
(17) The marked inhibition of periodic acid-induced blastogenesis, exerted by Fremy's salt and by bisulfite, was attributed to the effect of the corresponding carbonyl addition derivatives formed in situ of the oxidized cell membranes.
(18) Both deoxyadenosine and deoxyguanosine, when incubated separately with OKT4 and OKT8 cells in the presence of EHNA, an ADA inhibitor, did not significantly inhibit lymphocyte blastogenesis to a greater extent in ARC patients than in controls.
(19) In vitro lymphocyte blastogenesis has been useful in the diagnosis of nickel allergy in humans, but has not been applied to predictive testing in animals.
(20) Phytohemagglutinin-induced lymphocyte blastogenesis, however, was depressed by water-soluable adjuvants.
Budding
Definition:
(p. pr. & vb. n.) of Bud
(n.) The act or process of producing buds.
(n.) A process of asexual reproduction, in which a new organism or cell is formed by a protrusion of a portion of the animal or vegetable organism, the bud thus formed sometimes remaining attached to the parent stalk or cell, at other times becoming free; gemmation. See Hydroidea.
(n.) The act or process of ingrafting one kind of plant upon another stock by inserting a bud under the bark.
Example Sentences:
(1) Serially sectioned rabbit foliate taste buds were examined with high voltage electron microscopy (HVEM) and computer-assisted, three-dimensional reconstruction.
(2) Small pieces of anterior and posterior quail wing-bud mesoderm (HH stages 21-23) were placed in in vitro culture for up to 3 days.
(3) They are capable of synthesis and accumulation of glycogen and responsible for its transfer to sites of more intense metabolism (growth, bud, blastema).
(4) Pupils who disrupt the learning of their classmates are dealt with firmly and, in many cases, a short suspension is an effective way of nipping bad behaviour in the bud."
(5) Tissue sections, taken from foliate and circumvallate papillae, generally revealed taste buds in which all cells were immunoreactive; however, occasionally some taste buds were found to contain highly reactive individual cells adjacent to non-reactive cells.
(6) They were formed by budding off from the cytoplasmic projections of the osteoblastic tumor cells.
(7) These antibodies were used to study the localization and synthesis of myosin heavy chain and tropomyosin in the limb buds of premetamorphic (stage VI-VII) tadpoles treated with triiodothyronine (T3) to induce metamorphosis.
(8) In contrast, sporoblasts and budding and free sporozoites in mature oocysts were labeled uniformly on the outer surfaces of their plasma membranes, indicating a uniform distribution of CS protein on these membranes.
(9) Other experiments further implicated actin in the budding process during virus maturation, as there appeared to be a specific association of actin in vitro only with nucleocapsids that have terminated RNA synthesis, which is presumably a prerequisite to budding.
(10) By the time the bud was half the diameter of the mother cell, it almost always bore a vacuole.
(11) The ICC assay demonstrated the production of infectious HIV-1 particles and budding of mature virions was observed by electron microscopy.
(12) We report now that the hormonal metabolite of vitamin D3, namely 1,25-dihydroxyvitamin D3, stimulates chondrogenesis in cultures of stage 24 chick embryo limb bud mesenchymal cells, as evidenced by morphologic changes as well as by increased transcription of collagen type II and core protein genes.
(13) Lysis ability was acquired by growth in (or transfer to) an osmotically stabilized environment, but only under conditions which permitted budding.
