| Title |
All-tissue_6hpa_rep1 |
| Sample type |
SRA |
| |
|
| Source name |
tadpole tail tissue
|
| Organism |
Xenopus tropicalis |
| Characteristics |
tissue: tadpole tail
regeneration timepoint: 6 hours post amputation
stage amputated: NF Stage 41 (3 days post fertilization)
genotype: Xtr.Tg(pax6:GFP;cryga:RFP;actc1:RFP)
|
| Treatment protocol |
The posterior third of an anestitized tadpole tail was amputated at NF stage 41. Tadpoles were replaced in media without anesthetiz and allowed to regenerated until desired collection timepoint.
|
| Growth protocol |
Xenopus were reared in 1/9 Modified Ringers solution at 23C.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
The regenerated tail was isolated from the tadpole and cells were dissociated into single cell suspension using Liberase, washed in PBS and sorted for fluoresence through an Aria III cell sorter.
