Answer:
The result implies that fat cells are committed to this fate, but not irreversibly determined.
Step-by-step explanation:
The expression of Myod is capable of converting a fibroblast to a skeletal muscle cell. Due to the fact that it can do this, it is therefore a model system in developmental biology for studying how a single initiating event can orchestrate a highly complex and predictable response. Recent findings indicate that Myod functions in an instructive chromatin context and it regulates muscle cell differentiation by inducing cell cycle arrest, a prerequisite for myogenic initiation. The protein is also involved in muscle regeneration. It activates its own transcription which may stabilize commitment to myogenesis.
