Expression of HTK on cultured erythroid cells. Purified immature BFU-E from human peripheral blood were cultured. The expression of HTK and glycophorin A on cultured cells was analyzed by FACS on (A) day 6 and (B) day 14. The morphology of cultured cells was also examined on (C) day 6 and (D) day 14 (May-Grünwald-Giemsa staining, original magnification × 400).
