Primary Objectives:
1. To determine if bone marrow progenitor cell harvest and i.v. transplantation is safe in children after traumatic brain injury.
2. To determine if late functional outcome is improves with stem cell transplantation compared to institutional, age, and severity of matched historical controls
Secondary Objective:
To accomplish in vitro bone marrow progenitor cell labeling using magnetodendrrimers. In vitro cell labeling with magnetodendrimers will be studied with in vitro magnetic resonance imaging to test labeling efficiency for future studies. |
