FGFs especially FGF8 promoted sheet-like architecture, cell proliferation, and survival as compared to the control.
Interestingly, the researchers observed that VEGF gradients can lead to different sprout morphology: positive VEGF gradients defined as invasion towards the source of VEGF induced filopodial extensions analogous to tip cell sprouts seen in vivo, but negative gradients instead promoted sheet-like migration analogous to vessel dilation.
We therefore hypothesized that enhancing cell sheet properties by introducing overexpression of a gene associated with angiogenesis, anti-fibrosis, and antiapoptosis could further promote sheet therapy.
When ES-derived cardiomyocytes alone were seeded onto temperature-responsive culture dishes, cell sheets were not created, whereas cocultures with cardiac fibroblasts promoted cell sheet formation.
Low 2,2,2,-trifluoroethanol concentration promoted β-sheet structures in SP-BN, which bind Thioflavin T, at acidic pH, whereas it promoted coiled coil structures at neutral pH.
These experiments suggest that ER reshaping events, specifically those promoting membrane sheet formation from tubules, are crucial for NE assembly.
These results are consistent with the notion that golli promotes process/membrane sheet formation, taking OPCs to an apparently more mature morphological state.
The suitable type II heterojunction structure between NaNbO3(100) and GO sheet promoted the interfacial charge migration to restrain their recombination rate, thereby improving the activity of hydrogen generation.
This implies that the prevascularized cell sheet promoted the vascularization of the tissue-engineered grafts.
In this study we found that an hMSCs cell sheet promoted network formation of HUVECs.
In vitro results indicated that the hMSCs cell sheet promoted the HUVECs cell migration to form networks in horizontal and vertical directions.
