Renal capsule assays using lateral mandibles from E10 Runx2-KO mice. (A-a) Renal capsule assay of lateral mandibles from E10 Runx2-KO mice. At 19 days post-transplantation, no growth of transplanted mandibles and flattened explants were observed. *Agarose agar. (A-b) Renal capsule assay of lateral mandibles from E10 Runx2-KO mice. Transplantation was performed beneath the kidney capsule of nude mice (KSN/Slc) together with a cationized gelatin sheet containing Usag-1 siRNA #304. White tissue was attached underneath the renal capsule after 19 days. (A-c) 3D micro-CT image of the tissue shown in panel 4A-b. Mineralized hard tissue, such as bone, dentin, or enamel, was not observed. (B) We performed renal capsule transplantation of mandibles from Runx2-KO mice, alone or with cationized gelatin containing PBS or Usag-1 siRNA (#304 and #903). The percentage of growing explants formed in renal capsule grafts 19 days post-transplantation was calculated by dividing the number of growing explants by the number of Runx2-KO mouse mandibles transplanted.
