Migratory
Definition:
(a.) Removing regularly or occasionally from one region or climate to another; as, migratory birds.
(a.) Hence, roving; wandering; nomad; as, migratory habits; a migratory life.
Example Sentences:
(1) Hence, the absence of NGF receptors on premigratory neural crest and early migratory neural crest cultures was not due to enzymatic alterations of the receptor.
(2) These observations suggest that the function of BMG is to evoke mesenchymal cell differentiation into prechondroblasts during the latent or migratory morphogenetic phase while the effect of the culture medium is to provide the bionutritional requirements for synthesis of hyaline cartilage matrix by chondrocytes during the patent phase of development.

(5) The migratory phase is transient and therefore permits analysis of factors regulating the motile activity of cells in tissues.
(6) In these populations it is necessary to consider the relations between emotional distress and socio-political context, particularly the processes of terror and intimidation and the conditions of migratory illegality and social marginality.

(9) These migratory properties of lymphoblasts are probably relevant to their migration into inflammatory sites in vivo.
(10) The alveolar macrophages were increased in number and size but marked cytoplasmic vacuolation and a paucity of lysosomes are consistent with our previous suggestion that the phagocytic and migratory properties of these cells are weakened or inhibited.
