Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This clinical trial aims to evaluate the safety and efficacy of an experimental tissue-engineered construct (TEC) based on amniotic membrane and calcium alginate for promoting epithelialization and improving scar quality in patients after cesarean section. The study will assess both biological and clinical indicators of wound healing, including cytokine dynamics (IL-6, IL-10), ultrasound characteristics, and patient-reported outcomes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The amniotic membrane (AM) is a natural biological material with regenerative and anti-inflammatory properties. In this study, a biodegradable tissue-engineered construct (TEC) combining amniotic membrane and calcium alginate is applied to the postoperative wound after cesarean section.

A total of 100 participants will be randomized into two groups:

1. Experimental group - TEC application to the postoperative wound.
2. Control group - standard postoperative wound care without TEC. Outcomes will include objective ultrasound measures of scar formation, cytokine profile changes, clinical scar evaluation (POSAS), and cosmetic appearance at 12 weeks.
