Latent
Definition:

Example Sentences:

(4) Evidence is presented that suggests that a major active component of human uterine angiogenesis factor is an activator of latent matrix metalloproteinases, of low M(r), called endothelial-cell-stimulating angiogenesis factor and that this factor is present in substantial quantities in a number of embryonic tissues.
(5) 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.
(6) Factors affecting survival are the level of the lesion, the age of the patient, and the latent period of the injury.
