Transmission electron micrographs of tendon constructs. (A)–(D) longitudinally sectioned micrographs. (A) The image shows the arrangement of collagen fibrils in between two tendon fibroblasts. Arrows point to membrane convolutions. Bar: 5 μm. (B) Parallel alignment of collagen fibrils in the ECM adjacent to a tendon fibroblast. Bar: 1 μm. (C) The electron micrograph displays collagen fibrils in the extracellular space in close proximity to a tendon fibroblast. Bar: 1 μm. (D) Collagen-deposition site on a fibroblast is shown. Bar: 500 nm ECM: extracellular matrix, IC: intracellular space.
