Researchers are one step closer to solving the mystery of why some vertebrates can regenerate their spinal cords while others, including humans, create
scar tissue after spinal-cord injury (SCI), leading to lifelong damage.
A staph infection creates a large amount of
scar tissue that can lead to chronic pain and loss of mobility.
When blood supply to the heart is blocked during a heart attack, cardiac colony-forming unit fibroblasts replace damaged tissue with collagen-based
scar tissue. "This is a problem because scarring of heart tissue can reduce the heart's ability to pump blood effectively," lead researcher James J.
When a serious wound is incurred, the biggest obstacle to healing is the generation of
scar tissue, which has different properties than normal skin that cause discomfort and can be unsightly.
Scar tissue has the potential to spread in any direction, including internally, throughout the body.
The formation of
scar tissue is a common by-product of wound repair, leading to serious clinical dysfunction and aesthetic problems.
Because heart muscle does not regenerate, the damaged areas are replaced with
scar tissue, which does not contract.

Required stitches: If you needed stitches because you had a tear, these stitches will heal, but sometimes they can leave you with
scar tissue at the perineum.
Researchers used mouse models to investigate the impact of 1,25D, a form of vitamin D that interacts with hormones, on the cells that form
scar tissue after a heart attack.
However, after an injury to the central nervous system, a special type of
scar tissue is formed which inhibits this regeneration.
