Theory 07/Damkohler Number/Wound healing
Healing Rate Is a Damkohler
The claim
Wound closure rate is set by the ratio of cell proliferation rate to nutrient transport rate, so a well-perfused wound heals faster even with the same cells.
01Mechanism
Cells must be supplied as they divide; when proliferation outpaces delivery, growth stalls at the diffusion limit.
02Prediction
Closure rate should track the Damkohler number.
03Refutation
Closure tracking cell density would remove transport.
