4 Fig. 3 Sections of epoxy resin-embedded cell aggregates cultured for one (A), five (B), seven (C), or fourteen (D) days (toluidine blue, x 128). JUNG U. YOO et al. J Bone Joint Surg Am 1998;80: ©1998 by The Journal of Bone and Joint Surgery, Inc.

5 Fig. 4 Sections of cell aggregates cultured for fourteen days and treated with dexamethasone (A and B) or TGF-β1 (C and D) alone (toluidine blue, x 64). JUNG U. YOO et al. J Bone Joint Surg Am 1998;80: ©1998 by The Journal of Bone and Joint Surgery, Inc.

6 Fig. 5 Sections of paraffin-embedded cell aggregates cultured for one (A), five (B), seven (C), or fourteen (D) days (toluidine blue, x 32). JUNG U. YOO et al. J Bone Joint Surg Am 1998;80: ©1998 by The Journal of Bone and Joint Surgery, Inc.

7 Fig. 6 Fluorescein-conjugated immunohistochemical analysis of frozen sections of cell aggregates cultured for one (1), five (2), seven (3), or fourteen (4) days. JUNG U. YOO et al. J Bone Joint Surg Am 1998;80: ©1998 by The Journal of Bone and Joint Surgery, Inc.
