How long does it take granulation tissue to heal?
This stage takes about 72 hours to complete. During this stage of healing, re-epithelialization and the replacement of the clot by granulation tissue occurs simultaneously. This stage is highly cellular with the primary cell types, including fibroblasts, keratinocytes, and endothelial cells.
Is granulation tissue a scab?
