Note: Conditional mutant.
Structure Level Pattern Image Note
TS24: femur Present 1G Perichondrium and periosteum are uniformly stained in the femur, but there are some unlabeled chondrocyte apparent.

Specimen Fig. 1I: postnatal adult; Gt(ROSA)26Sortm1Sor/Gt(ROSA)26Sor+, Twist2tm1.1(cre)Dor/Twist2+ (more )
Note: Conditional mutant.
Structure Level Pattern Image Note
TS28: tibia Present Regionally restricted 1I Staining is observed in chondrocytes and osteoblasts in the growth plate of the tibia.

Note: Conditional mutant.
Structure Level Pattern Image Note
TS28: tibia Present Regionally restricted 1J Staining is observed in the cortical bone. Staining is observed in the chondrocytes in growth plate cartilage. There are occasional clones of chondrocytes that fail to stain.
TS28: perichondrium Present 1J Staining is observed in the osteoblasts of the perichondrium, periosteum and endosteum.
TS28: periosteum Present 1J Staining is observed in the osteoblasts of the perichondrium, periosteum and endosteum.
