Summary
Decellularized urinary bladder submucosa scaffolds and tendon-derived hydrogel were tested for skin wound healing in rabbits. Submucosa scaffolds demonstrated superior efficacy in promoting skin regeneration compared to hydrogel and control groups.
Area of Science:
- Biomaterials Science
- Regenerative Medicine
- Tissue Engineering
Background:
- Skin injuries pose significant clinical challenges requiring effective regenerative strategies.
- Biomaterial scaffolds are crucial for promoting wound healing and tissue regeneration.
- Decellularized extracellular matrices offer promising biocompatibility for tissue repair.
Purpose of the Study:
- To evaluate the efficacy of decellularized urinary bladder submucosa scaffolds and tendon-derived hydrogel in promoting skin wound healing.
- To compare the healing progression and outcomes of these biomaterials against a control group.
- To assess the histopathological changes indicative of skin regeneration.
Main Methods:
- A controlled study involving 36 rabbits with induced 2 cm diameter skin injuries.
- Random assignment into three groups: control (sutured only), submucosa scaffold treatment, and tendon-derived hydrogel treatment.
- Histopathological analysis of skin specimens at multiple time points (post-injury days 8, 14, 21, and 24).
Main Results:
- Both tested biomaterials influenced wound healing progression compared to the control.
- The decellularized urinary bladder submucosa scaffold group exhibited a noticeable superiority in healing stages.
- Histopathological evaluation confirmed enhanced regenerative processes in the submucosa scaffold group.
Conclusions:
- Decellularized urinary bladder submucosa scaffolds are effective in promoting skin wound healing.
- Tendon-derived hydrogel also shows potential, but submucosa scaffolds demonstrate superior regenerative capacity.
- These findings support the use of submucosa scaffolds in regenerative strategies for skin defects.

01:24Ostomy Care
Introduction
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:

01:24Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
