CXCR4 and hereditary elliptocytosis: Additionally, CXCR4 expression was higher in EC tissues than in NE tissues (P = 0.000), in HE tissues (P = 0.000) and in AHE tissues (P = 0.000), whereas there were no differences between AHE and HE tissues (P = 0.111), between AHE and NE tissues (P = 0.172), or between HE and NE tissues (P = 0.443).
