Figure 1: In vitro adherent cells from decidual tissues. (a) Representative photomicrograph of spindle-shaped adherent cells isolated by αMEM and 10% FBS. (b) Cells isolated in vitro by serum-deprived medium (Quantum 333) at early passages. (c) Another population of cells was in vitro isolated contextually with EDT-MSC. These elements share similarities with endothelial cells forming a monolayer of polygonal, sometimes binucleated cells. Original magnification 100x.
