ATAC-seq Analysis of Chromatin Accessibility in p53 Deficient Spermatogonial Stem Cells for High Frequency Transformation into Pluripotent State
Spermatogonial stem cells (SSCs) could transform into pluripotent state in long term culture without introduction of exogenous factors. And p53 deficiency rescued SSCs from extensive cell apoptosis during transformation induced by rewriting of methylation profiles in SSCs. Notably, p53 is believed as a key bottle-neck for reprogramming. Based on these studies, we compared the difference of chromatin accessibility between SSCs from wild type and p53 deficient SSCs mice using ATAC-seq, to explore the potential mechanism at chromosome level. And RNA-Seq was subsequently exerted to verify the predicted genes and related pathways in SSCs transformation. This result further reveals the role of p53 in regulating SSCs fates, which provide hints new insight for understanding the biological characteristics of germline stem cells,  basic and clinic researchand molecular mechanisms of reprogramming and tumorigenesis.
