ABSTRACT
BACKGROUND:
Umbilical cord mesenchymal stem cells (UC-MSCs) are a kind of pluripotent stem cells capable of relieving inflammation and edema in injured areas, promoting microvascular regeneration and improving wound healing.OBJECTIVE:
To explore the therapeutic effects of UC-MSCs transplantation on acute traumatic brain injury (TBI) in rats and the effect on microvessel density of the rat brain tissue.METHODS:
Thirty Sprague Dawley rats were randomly divided into three groups, control group, TBI model group and UC-MSCs treatment group (n=10 per group). TBI models were made in the rats by free fall method. US-MSCs (1.5×106) were infused through the cerebral ventricle in the rats. Neurological severity scores were assessed at 24 hours after cell transplantation. The microvessel density in the injured brain tissue was detected using immunohistochemistry method at 14 days after cell transplantation. RESULTS ANDCONCLUSION:
Compared with the TBI model group, the microvessel density value was significantly increased after UC-MSCs transplantation (P < 0.05), and the neurological severity score also became better in the UC-MSCs treatment group (P < 0.05). In summary, UC-MSCs transplantation can effectively improve became vascular remodeling and have a good neuroprotection in acute TBI rats.
