Rattus norvegicus Raw sequence reads

Twelve rats were randomly divided into three groups: the expanded group (n = 4), the sham operated group (n = 4), and the normal control group (n = 4). the rats in the expanded group underwent one milliliter of silicone tissue expander implatation in scalp. The sham operated group underwent the same surgical process except for the placement of a silicone sheet without saline injection. The normal control group was kept intact. Sterilized saline was injected every 2 days from the seventh day after surgery in the expanded group (1 mL per injection) until the silicone expander was enlarged to a volume of 9 mL at day 28. All analyses were performed on the skin located on the top of the dome induced by the skin expander. The specimens were collected at 48 h after the last injection.
