Abstract
Carcinoembryonic antigen‐cell adhesion molecule‐1 (CEA‐CAM‐1) positive stem cells have been visualized in the white matter and gray matter in the cerebral cortex of adult rats. Similar cells have also been isolated and characterized from the skeletal muscle of and peripheral vasculature of adult mammals, including humans. The current study was undertaken to determine the location of these cells with respect to the brains of the adult pig. Adult pigs were euthanized following the guidelines of Fort Valley State University's IACUC. The heads were fixed by immersion fixation, the brains isolated, cryosectioned and stained with an antibody diagnostic for adult pluripotential stem cells, i.e. CEA‐CAM‐1. The current study will discuss the location with respect to the white and gray natter in the adult pig. Studies are ongoing to address their functional significance in neuronal injury and repair.
