blastogenesis

[blas″to-jen´ĕ-sis]

1. development of an individual from a blastema, i.e., by asexual reproduction.

2. transmission of inherited characters by the germ plasm.

3. morphological transformation of small lymphocytes into large lymphocytes (lymphoblasts) that accompanies lymphocyte activation.

blas·to·gen·e·sis

(blas'tō-jen'ĕ-sis),

1. Reproduction of unicellular organisms by budding.

2. Development of an embryo during cleavage and germ layer formation.

3. Transformation of small lymphocytes of human peripheral blood in tissue culture into large, morphologically primordial blastlike cells capable of undergoing mitosis; can be induced by various agents including phytohemagglutinin, concanavalin A, certain antigens to which the cell donor has been previously immunized, and leukocytes from an unrelated individual.

blastogenesis

(1) The theory that inherited characteristics are transmitted from parent to offspring by germ plasm. Similar to the concept of embryogenesis.
(2) Reproduction of an organism by budding.
(3) The transformation of small lymphocytes into larger cells that are capable of undergoing mitosis. See blast transformation.
