From: Cancer-associated fibroblasts promote the progression of endometrial cancer via the SDF-1/CXCR4 axis
Expression of SDF-1α and CXCR4 in EC. a SDF-1α protein expression upregulation accompanied clinical EC development and progression. b Kaplan-Meier survival curves for overall survival according to SDF-1α staining level: negative expression, low expression, and high expression. Overall survival was significantly different in the three groups (P = 0.039). c Kaplan-Meier survival curves for recurrence according to SDF-1α staining level: negative expression, low expression, and high expression. Recurrent survival was significantly different in the three groups (P = 0.032). d CXCR4 expression increased gradually in endometrial tissues as they progressed from NE to HE to AHE and finally to EC tissues
