Hemokinski (C-C motivni) ligand 21 (CCL21) jest mali citokin hemokinske porodice CC. Ovaj hemokin je poznat i kao 6Ckin (jer ima šest konzerviranih cisteinskih ostataka umjesto četiri cisteina tipska za hemokine), egzodus-2 i sekundarni limfoidni tkivni hemokin (SLC).[5][6][7]

Gen za CCL21 se nalazi na ljudskom hromohomu 9. CCL21 izaziva svoje efekte vezanjem za ćelijsku površinu hemokinski receptor poznat kao CCR7.[9]

U ljudskim limfnim čvorovima, fibroblastne mrežaste ćelije (FRC) eksprimiraju CCL21 kao hemoatraktant koji nevine, CCR7 eksprimirajuće T-ćelije vodi u zonu T-ćelija.[10]
