When does epithelial cell proliferation and migration typically start after a wound occurs?

Within 1 hour
Within 4 hours
Within 8 hours
Within 24 hours

The correct answer is: Within 8 hours

Epithelial cell proliferation and migration generally begin within 24 hours after a wound occurs, marking a critical phase in the wound healing process known as re-epithelialization. This timing correlates with the inflammatory phase of healing, where cytokines and growth factors released from platelets and inflammatory cells stimulate keratinocytes to migrate to the wound site. This process is essential for wound closure, as keratinocytes move across the wound bed to cover the defect and restore the integrity of the skin. Understanding this timeline is important in clinical practice, as it informs wound management strategies. This knowledge helps healthcare professionals to anticipate the healing timeline, make appropriate treatment decisions, and assess the progress of wound healing effectively.
