Sentence examples for origin of migration from inspiring English sources

Using this approach, the origin of migration and, by extrapolation, the stem cell niche has been predicted to reside at the base of the crypt [35].

These types of assays are much slower and are generally difficult to quantify because of the absence of a sharply defined origin of migration.

When the completed two layer gels were sectioned perpendicularly to the tumor cell monolayer shortly after the seeding of the cells, the monolayer was seen as a thin line of cells that clearly defines an origin of migration or start position.

Furthermore, since at the beginning of the assay the cells are arranged in a monolayer that defines a sharp origin of migration, this assay is also easily quantifiable and provides information on behavior of the entire population of the tumor cells.

MtDNA coalescence ages, phylogenetic and dispersal patterns that neither fit with long term in situ development >40 kya nor southward population expansions <8 kya indicate a broader timeframe and geographic origin of migrations [ 5, 28, 30].
