The stem maintains close proximity of the two moieties, causing fluorescence to be quenched by energy transfer.
When the stem of a woody plant grows in a non-vertical orientation it forms reaction wood, a specialized secondary xylem that helps the stem maintain a certain orientation and re-orients growth [ 20].
On the contrary, stems were maintained at a given curvature after 7-9 days.
Wnt signaling controls stem behaviors, maintains stem cell habitus, and regulates cell migration and differentiation [ 5- 7].
CCL11 also impaired their performance on the fear conditioning and memory tasks, and inhibited the differentiation of neural stem cells maintained in a culture dish.
Mesenchymal stem cells maintained a viability above 90% on all chitosan scaffolds.
How are stem cells maintained in the right numbers?
But how is a stable population of stem cells maintained throughout the life of the organism with constant cell division?
By dividing asymmetrically, cancer stem cells maintain the stem cell pool and simultaneously generate committed cells that form tumor mass [ 32].
Cells were cultured (over night) in serum-free stem cells maintaining medium (STEM CELL technologies, 09650) supplemented with cytokines mSCF (50 ng/ml; Peprotech, 250-03) and TPO (50 ng/ml; Peprotech, 315-14).
