Sentence examples for migration of progenitor from inspiring English sources
Linked to distinct matrix remodeling, we demonstrate a myocardium-wide proliferative response and radial migration of progenitor cells.
In particular, we report dramatic upregulation of a regeneration-specific matrix in the epicardium that precedes the accumulation and migration of progenitor cells.
In cultured cortical slices of millimeter wide, the radial migration of progenitor cells can be significantly disrupted by a treatment of Sema3A at concentrations ranging from 0.1 to 1 μg/ml, which is achieved by masking the endogenous gradient expression of Sema3A4.
Similar to short migration (2 photon experiments), we did not find any evidence of long-distance migration of progenitor cells labeled with CTO.
In adults of many species of vertebrates, migration of progenitor cells into damaged brain areas can allow for replenishment of depleted neurons.
PAX3 is a key determinant of somatic myogenesis and, is involved in the migration of progenitor cells to the dermomyotome region of the somite where they grow and divide in the presence of growth factors.
However, Flk1−/− ES cells can differentiate into both lineages in vitro [14], indicating that Flk-1 is required for the migration of progenitors into the proper microenvironment during embryogenesis.
Strong arguments favor a direct induction of this later event in the prospective neocortex rather than to result from migration of progenitors from the proliferative region of the ventral telencephalon.
A further category of genes identified were those that potentially affect the migration of progenitors into the nascent pharynx (WDR3 and WDR36), highlighting the fact that migration of stem cells and/or their progeny is an essential step in pharynx regeneration.
Whilst the generation of olfactory neurons throughout life may be of less significance in humans than in rodents and other macrosmatic species, the long-term perturbation of the SEZ neurogenic output post-ischaemia, possibly due to ectopic migration of progenitors (Fig. 5E), revealed by our results might lead to additional side-effects even in humans.
Since this early restitution is not based on cellular proliferation but on migration, mobilization of progenitor cells is not required.
