Organ, in biology, a group of tissues in a living organism that have been adapted to perform a specific function. In higher animals, organs are grouped into organ systems; e.g., the esophagus, stomach,... nervous system Nervous system, organized group of cells specialized for the conduction...
1、Cells, Tissues, and OrgansThe Cell The body can be studied from its simplest to its most complex level, beginning with the cell, the basic unit of living organisms . Cells carry out metabolism, the sum of all of the physical and chemical activities that occur in the body. Providing th...

Classically, myogenic precursor cells derive from somites, and connective tissues derive from lateral plate mesoderm (LPM). Here the authors identify LPM derived fibroblasts that turn on a myogenic program and fuse to muscle fibers at muscle-tendon junctions, introducing fibroblast transcripts into myofi...
