Sentence examples for heart cell populations from inspiring English sources

These phases are analogous to the differentiation of the two progenitor heart cell populations in mammals, termed the first and second heart fields.

In this study, a linear model was used to describe GeneChip PM probe signals and to determine effects of three types of stressors on gene expression in two neonatal rat heart cell populations, consisting of CM that are known to be terminally differentiated cells and fibroblasts that still have the capacity to undergo mitosis.

We demonstrated, using a FACS analysis, that CD41/Flk1 double-positive cells of putative vasculogenic and hematopoietic potential comprise surprisingly high proportion (2.68 %) of entire heart cell population at 12.5 dpc.

Other methods for cardiomyocyte enrichment depend on genetic modification of hESCs and include positive selection for the expression of reporter and/or marker genes driven by cardiac-specific promoters in hESCs (lineage selection) or negative selection against proliferating cells in the heart cell population using a suicide gene approach.

As defects in the septum are the source of many congenital heart defects, a better understanding of the heart cell precursor populations and how they interact could help develop treatments for these conditions.

As with cDNA microarray experiments utilizing whole heart tissue with mixed cell populations, our findings may also reflect a change in the predominance of a particular cell type in each tissue sample.

Great attention has recently been given to selected subsets of circulating CD34+ cells in patients with ischemic heart disease, as these cell populations might include those involved directly or indirectly in vascular repair.

In zebrafish, real-time studies using fluorescent markers have furthered the concept of the first and second heart fields as distinct progenitor cell populations similar to those seen in mammals.

However, complexities of muscle structure and the heterogeneity of cell populations in the heart make in vivo studies and in vitro studies of the whole-heart preparations problematic to identify the primary cause and mechanisms underlying cardiotoxicity at the cellular level.

However, progressing one step further to tissue engineered heart valves that contain viable and phenotypically appropriate cell populations will result in growth capable heart valves that can remodel constructively and synchronously with the patient's somatic growth.

Some cell populations such as heart, the pericardial region, blood cells, muscle fibers, skin, and lower jaw primordial are domains of Gli3 expression in mouse but not so far described in zebrafish.
