Fig. 4From: Important role of the SDF-1/CXCR4 axis in the homing of systemically transplanted human amnion-derived mesenchymal stem cells (hAD-MSCs) to ovaries in rats with chemotherapy-induced premature ovarian insufficiency (POI)Elevated levels of SDF-1 in serum and ovaries are induced by chemotherapy in rats with POI. SDF-1 concentrations in the serum (a) and supernatant of homogenized ovarian tissue (b) from the control and POI groups were measured using ELISA. *P < 0.05 and **P < 0.01Back to article page
