Fibroblasts Organize the Collagen of the Extracellular Matrix By

Question

Fibroblasts organize the collagen of the extracellular matrix by
A)cutting and rejoining the fibrils.
B)processing procollagen into collagen.
C)twisting fibrils together to make ropelike fibers.
D)pulling the collagen into sheets or cables after it has been secreted.

Accepted Answer

Fibroblasts secrete collagen into the extracellular matrix and then pull on it to organize it into sheets or cables. They also have the ability to remodel and rearrange the collagen over time to adapt to changing tissue demands. They do not cut or rejoin the fibrils, process procollagen into collagen, or twist fibrils together to make ropelike fibers.
