Figure 4. c-kit⁺-enriched bone marrow cells gave rise to ameloblast- and odontoblast-like cells without cell fusion. (A,B) FISH for the Y chromosome (Y-chm) and staining for EGFP reveal that ameloblast-like c-kit⁺-enriched bone marrow cells did not have a Y chromosome, (C,D) nor did they have more than 2 X chromosomes (X-chm). (E,F) Odontoblast-like c-kit⁺-enriched bone marrow cells did not have a Y chromosome, (G,H) nor did they have more than 2 X chromosomes. Am, Ameloblasts; Od, Odontoblasts; Mes, Dental Mesenchyme. Bar = 10 µm.
