Mouse Digits Regeneration RNA-seq Data
Mice were subjected to hindlimb distal phalanx (P3) amputation to digit 3. For each amputation, mice were anesthetized, the hindlimb claw was extended, and the distal phalanx and footpad was sharply dissected.  A regenerating distal phalanx was generated by amputating =33% of the P3. Skin wounds were allowed to heal without suturing. Mice were subjected to micro-computed tomography (microCT) one day prior to surgery and immediately after amputation to confirm = 33% removal of the P3. Any digit that did not fall within the = 33% amputation guideline was omitted from the study. Based on our criteria, 17 animals were removed from the study resulting in a final total of 30 mice.  P3 mice were collected at hours (0h, 3h, 6h ,12h, and 24h), and days (3d, 7d, 14d, and 21d). Each time point contained 3 mice, except day 7 (6 mice). At the time of P3 collection, samples were immediately immersed in RNAlater for 24h at 4C. The digits were then removed from RNAlater and stored at -80C until performing RNA sequencing. Overall design: 30 mice with digits amputation. We performed time course RNA-seq on these amputated digits to characterize transcriptome dynamics of regeneration
