CB-MNCs@ CS/HEC/GP promote wound healing in aged murine pressure ulcer model.

ABSTRACT:

Background

Non-healing pressure ulcers impose heavy burdens on patients and clinicians. Cord blood mononuclear cells (CB-MNCs) are a novel type of tissue repair seed cells. However, their clinical application is restricted by low retention and survival rates post-transplantation. This study aims to investigate the role of thermo-sensitive chitosan/hydroxyethyl cellulose/glycerophosphate (CS/HEC/GP) hydrogel encapsulated CB-MNCs in pressure ulcer wound healing.

Methods

Pressure ulcers were induced on the backs of aged mice. After construction and validation of the characterization of thermo-sensitive CS/HEC/GP hydrogel, CB-MNCs are encapsulated in the hydrogel, called CB-MNCs@CS/HEC/GP which was locally applied to the mouse wounds. Mouse skin tissues were harvested for histol
