Transdifferentiation of Muscle Satellite Cells to Adipose Cells Using CRISPR/Cas9-Mediated Targeting of MyoD.

Brown adipocytes dissipate energy through non-shivering thermogenesis mediated by UCP1 protein, hence representing a powerful target to overcome obesity due to energy surplus. However, brown adipocytes are scarce in adult humans, especially in obese subjects, urging the development of novel strategies to boost the number of these thermogenic adipocytes from a therapeutical perspective. In this regard, transdifferentiation of myoblasts into brown adipocytes represents a promising approach. Here, we describe a method that we have recently developed to transdifferentiate myoblasts into brown adipocytes through CRISPR/Cas9-medidated targeting of MyoD, the master myogenic regulatory factor.
