FateMappingAxolotlEmbryosinEarlyGastrulation
BackgroundSince different amphibians execute gastrulation in different ways, the study of amphibian gastrulation has been complex. A popular method used to examine and explore gastrulation and determine the future fate of cells in amphibian embryos is the visualization of cell movement by application of a vital (non-toxic) dye to the region of interest on the amphibian embryo. This process of observing morphogenetic ......阅读全文
