title: Twist of fate for skeletal muscle mesenchymal cells.
abstract: Skeletal muscles are composed of different types of fibres. Can these be thought of as distinct lineages with specific lineage-restricted progenitors? A provocative study now proposes that mesenchymal cells expressing the transcription factor Twist2 act as myogenic progenitors with selective type IIb fibre-differentiation potential.
