    Human Fetal Membrane-Mesenchymal Stromal Cells Generate Functional Spinal Motor Neurons In Vitro

    Scientists demonstrated that human fetal membrane-MSCs could give rise to spinal motor neurons, by the sequential exposure to specific factors that induced a neuralization, caudalization, and ventralization of undifferentiated cells.
