The Claim
Postnatal wound-specific fibroblasts (PWFs), which appear after birth and are not present in embryonic wounds, express higher levels of Timp1, Cxcl12, and Ccl7, and their presence is associated with impaired organ-level regeneration and increased nerve growth (hyperinnervation) in mouse skin.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After birth, certain skin cells that show up in wounds—called PWFs—don’t exist in baby or embryo wounds. These cells are linked to worse healing and too much nerve regrowth in mice.
See the scientific wording
Postnatal wound-specific fibroblasts (PWFs), which emerge after birth and are absent in embryonic wounds, express elevated levels of Timp1, Cxcl12, and Ccl7, and their presence is associated with failed organ-level regeneration and hyperinnervation in mouse skin.
What the research says
1 studyStudy: Hyperinnervation inhibits organ-level regeneration in mammalian skin.
The study found that certain cells in newborn mouse skin, which aren’t there in embryos, produce signals that stop full healing and cause too many nerves to grow back. Blocking those signals helps the skin heal better.
