Visualization of the Skeletal Muscle Stem Cell Niche in Fiber Bundles
Here, we provide a method for the visualization of MuSCs on muscle fibers in their intact niche. Our method relies on mechanical teasing of fiber bundles from fixed skeletal muscles.

Non-canonical muscle stem cells and other lessons from regenerative
During tail regeneration, DMS-progenitors first differentiate into PAX7 + MuSCs before giving rise to tail musculature. Dotted white lines represent amputation planes for limb and tail.

Imaging analysis for muscle stem cells and regeneration
In a study conducted by Schmalbruch in 1978, rat hind-limb skeletal muscles were freeze-fractured, and an electron microscope was used to characterize MuSC shape and its relationship to

8.5 Types of Muscle Fibers – Human Physiology
Most muscles possess a mixture of each fiber type. The predominant fiber type in a muscle is determined by the primary function of the muscle. These different fiber types can be easily identified

The muscle stem cell niche at a glance
MuSCs reside between an individual myofiber and an enwrapping basal lamina, defining the immediate MuSC niche. Additional cell types outside the basal lamina, in the interstitial space,

Muscle Satellite Cell Cross-Talk with a Vascular Niche Maintains
We show that MuSCs express abundant VEGFA, which recruits endothelial cells (ECs) in vitro, whereas blocking VEGFA using both a vascular endothelial growth factor (VEGF) inhibitor and MuSC-specific
