Isolation, culture and characterization of adult carotid body-derived cells.
Recent studies indicate that carotid body (CB) could be a suitable cell source for cell therapy in Parkinson's disease. We have isolated and successfully expanded in culture as monolayer adult CB-derived cells using a modification of the culture medium employed for bone marrow multipotent adult progenitor cells (MAPCs). These cells express variable amounts of tyrosine hydroxylase (TH), beta-III tubulin and Sox2. In addition, CB-derived cells showed high expression of Sox2 related to a high rate of proliferation and consistent with an undifferentiated state. Under culture conditions that reduced cell proliferation, Sox2 expression decreased while TH and beta-III tubulin expression was increased. This could indicate that the differentiation of some cells occurs in the culture, thus accounting for a certain neural differentiation potential of CB-derived cells.
