epigenetic reprogramming

Epigenetic reprogramming is the process where cells reset or change their gene activity without altering the underlying DNA sequence. This involves modifications to chemical markers on DNA or associated proteins, which turn genes on or off. Such reprogramming allows cells to develop into different types or revert to a more flexible, stem cell-like state. It plays a crucial role during early development and in creating induced pluripotent stem cells, enabling specialized cells to regain a more versatile status and potentially repair or replace damaged tissues.
