RNA-seq of Tregs from injured mouse neonatal and adult tendon and spleen.
We report transcriptomic differences between neonatal and adult Treg responses to tendon jury using NGS sequencing. We performed tendon injuries to neonatal mice at P5 and 4-6 month old adult mice and isolated Tregs by FACS (CD4-PE+, Foxp3-GFP+) from injured tendons and autologus spleens 14 days after inury. We then performed RNA-sequencing with biological triplicates to distinguish unique transcriptomic signatures that can illuminate the role of Tregs in neonatal tendon regeneration. Tregs from neonatal tendon show a type 2 immune signatures with a unique gene signature that is distinc from canonical Treg activation, while adult Tregs demonstrate a type 1 signature. Overall design: Examination of Tregs from neonatal and adult mice FACS sorted from injured tendon and spleen 14 days after injury.
