Response of astrocytes and microglia/macrophages to brain injury after bone marrow stromal cell transplantation: A quantitative study

▶ BMSC transplantation causes alterations in cell number in the injured brain. ▶ The effects of BMSC action are dependent on the site of their administration. ▶ BMSCs transplanted intracerebrally increase the number of astrocytes. ▶ BMSCs administered intravenously enhance the number of microglia/macrophages.
