Sentences with phrase «epithelial cell progenitors»

The researchers knew they faced a major challenge: sorting and separating «sticky» epithelial cell progenitors without destroying them.

Further tests suggested that epithelial cell progenitors helped by restoring the connection between cells called myoepithelial contractile cells and the lacrimal gland's secretory cells, which produce tears.

Not exact matches

Transient Silencing of 14 -3-3sigma promotes proliferation of p63 - positive progenitor cells isolated from human breastmilk in mammary epithelial cell culture.

In this study, the researchers used progenitor cells that were poised to become epithelial tissue, a key component of the lacrimal gland.

Once the bacterial cell signaling protein cagA reaches the host cytosol, it is capable of altering subsequent generations of progenitor cells, leading to the development of cancer through changes in mitotic activity, apoptosis, cellular assembly, and signaling.26 Although it should be noted that while the presence of the cagA protein doubles the risk of gastric cancer, cagA - negative strands also increase the risk of distal gastric cancer.27 Additional H pylori virulence factors include babA2, which encodes bacterial adhesion with gastric epithelial cells, and vacuolating cytotoxin A, which is encoded by the gene vacA.28, 29 H pylori strains carrying some combination of the babA2, cagA, and vacA genes were associated with the highest risk of developing intestinal metaplasia.

Subsequent single - cell flow cytometric assays linked this shorter G1 phase to the more rapid loading of minichromosome maintenance (MCM) helicase complexes when compared to differentiated cells with longer G1 phases (neural progenitor cells and retinal pigmented epithelial cells).

We have recently shown that in avian embryos, muscle formation is initiated by Delta1 - positive neural crest cells migrating from the dorsal neural tube that, in passing, trigger NOTCH signalling and myogenesis in selected epithelial somite progenitor cells, allowing them to migrate into the nascent muscle to differentiate.

Initial reprogramming efforts used adult mouse limbal progenitors (epithelial cells which express Sox2, Klf4, and Myc) which the group reprogrammed to iPSCs using embryonic stem cell CM (ESCM) supplemented with MAPK and GSK3 inhibitors as previously described [4, 5].

The researchers conclude that this could be owing to the bone marrow - derived MSCs being able to act as progenitor cells, similar to alveolar epithelial type II cells.

In chick embryos, skeletal muscle formation is initiated by migrating Delta1 - expressing neural crest cells that trigger NOTCH signaling and myogenesis in selected epithelial somite progenitor cells, which rapidly translocate into the nascent muscle to differentiate.

Considering that miR - 142 is highly expressed in human BCSCs, but weakly expressed or undetectable in the stem / progenitor population of the mammary epithelial cells, our result suggest that the upregulation of miR - 142 and its enhancement of the miR - 150 expression seem to be especially relevant in the breast tumor progression in vivo.
