Lane AgeStructure Size Not Specified Amount Genetic BackgroundMutant Allele(s)Sex Note
E17.5 tip E17.5 TS25: upper jaw incisor Present Not Specified; total RNA CD-1 Not Specified incisor tip segment.
E17.5 E17.5 TS25: upper jaw incisor Present Not Specified; total RNA CD-1 Not Specified part of the tooth that is adjacent to the incisal tip.
P0 tip P0 TS27: upper jaw incisor Present (a) Not Specified; total RNA CD-1 Not Specified incisor tip segment.
P0 P0 TS27: upper jaw incisor Present (b) Not Specified; total RNA CD-1 Not Specified part of the tooth that is adjacent to the incisal tip.
P1 tip P1 TS27: upper jaw incisor Present Not Specified; total RNA CD-1 Not Specified incisor tip segment.
P1 P1 TS27: upper jaw incisor Present (c) Not Specified; total RNA CD-1 Not Specified part of the tooth that is adjacent to the incisal tip.
P2 tip P2 TS27: upper jaw incisor Present Not Specified; total RNA CD-1 Not Specified incisor tip segment.
P2 P2 TS27: upper jaw incisor Present (c) Not Specified; total RNA CD-1 Not Specified part of the tooth that is adjacent to the incisal tip.
P10 tip P10 TS28: upper jaw incisor Present (d) Not Specified; total RNA CD-1 Not Specified incisor tip segment.
P10 P10 TS28: upper jaw incisor Present (d) Not Specified; total RNA CD-1 Not Specified part of the tooth that is adjacent to the incisal tip.
Notes:
(a) Expression was significantly increased at P0 compared with E17.5.
(b) Expression was significantly increased at P0 compared with E17.5. Expression was found to be significantly higher in the adjacent segment than in the incisal tip segment at this age.
(c) Expression was found to be significantly higher in the adjacent segment than in the incisal tip segment at this age.
(d) Expression decreased at later developmental stages.
