Intramuscular fat (IMF) content is a critical factor affecting meat flavor, juiciness, tenderness, and color. Therefore, the improvement of IMF content is one of the hotspots of animal science research. Fat deposition is the result of a combination of increased number of fat cells and cellular hypertrophy. In addition, transcription factors can influence the number of adipocytes and regulate lipid metabolism. The progress of the transcription factors regulating adipocyte differentiation in beef cattle, including IMF cell sources, and promoting or inhibiting adipogenic differentiation of transcription factors is reviewed in this paper.

转录因子调节肉牛的脂肪细胞分化。

肌内脂肪（IMF）含量是影响肉类风味，多汁，嫩度和颜色的关键因素。因此，提高IMF含量是动物科学研究的热点之一。脂肪沉积是脂肪细胞数量增加和细胞肥大共同作用的结果。另外，转录因子可以影响脂肪细胞的数量并调节脂质代谢。本文综述了调节肉牛脂肪细胞分化的转录因子（包括IMF细胞来源），促进或抑制脂肪细胞脂肪分化的研究进展。
