Developmental expression of chemokine-like factor 1, a novel member of chemokines family, in postnatal rat cerebral cortex

► CKLF1 mRNA expression was decreased progressively from birth to adulthood. ► CKLF1 protein expression was also decreased progressively from birth to adulthood. ► The localization of CKLF1 was related to cell migration and myelination during development.
