Trophoblast motility in a gelatin hydrogel New Rochelle, NY, December 18, 2020--Trophoblast cells, which surround the developing blastocyst in early pregnancy, play an important role in implantation in the uterine wall. A new multidimensional model of trophoblast motility that utilizes a functionalized hydrogel is described in the peer-reviewed journal Tissue Engineering, Part A.

This valuable new tool, based on a methacrylamide-functionalized gelatin hydrogel, can be used for three-dimensional trophoblast spheroid motility assays. It can resolve quantifiable differences in outgrowth area and viability in the presence of a known invasion promoter and a known invasion inhibitor.
