Setton's lab exposed the hiPSCs to a variety of different growth factors and culture media to coax them into first developing markers for, and then fully forming into, notochord cells. (sciencedaily.com)
Some of this difference is driven by slightly different growth factors; for example, VONG looks at book - to - price ratios, medium - term growth forecasts and historical sales - per - share growth, while IWY only uses the latter two factors. (etf.com)
After creating stem cell aggregates with microparticles containing different growth factors, the researchers observed a hemispherical organization of cells for several days, with the different cells remaining spatially segregated. (sciencedaily.com)
