Prolonged FGF signaling is necessary for lung and liver induction in Xenopus.

BMC developmental biology | 2012

FGF signaling plays numerous roles during organogenesis of the embryonic gut tube. Mouse explant studies suggest that different thresholds of FGF signaling from the cardiogenic mesoderm induce lung, liver, and pancreas lineages from the ventral foregut progenitor cells. The mechanisms that regulate FGF dose in vivo are unknown. Here we use Xenopus embryos to examine the hypothesis that a prolonged duration of FGF signaling from the mesoderm is required to induce foregut organs.

BioRad Helios Gene Delivery System (tool)

RRID:SCR_019723

Handheld gene delivery system that provides direct transfection into a range of targets in vivo. It uses adjustable low pressure helium pulse to sweep DNA, RNA, or biomaterial coated gold microcarriers from a plastic cartridge directly into target cells.
