title: GSM6722161: atac_HEAD_161519; Ambystoma mexicanum; ATAC-seq
library_construction_protocol: The sample was performed from 20,000 cells isolated from transgenic animals. Limb connective tissue cells were used for FACS, and then used for library preparation immediately. We performed ACR profiling analysis using data obtained from ATAC-seq libraries of developmental limb buds (stage 40/41, stage 46 proximal and distal parts), and mature limb at different segments (mature UA vs LA vs hand). Therefore, we also performed libraries from the mature arm and 5, 9, 13 dpa (13 dpa blastema data have two different positions like proximal and distal parts) regenerating arm blastema.
