Description: The use of bone marrow stem cells (BMSCs) was investigated for gene therapy of X-linked Alport Syndrome. Alport syndrome is a progressive nephropathy resulting from loss of the alpha3/alpha4/alpha5 network of type IV collagen from the glomerular basement membrane. Type IV collagen includes six homologous chains, alpha1-alpha6, encoded by COL4A1  to COL4A6, respectively. X-linked Alport syndrome results from a mutation in the COL4A5 gene. In this thesis, it was shown that BMSCs undergo a degree of podocytic differentiation when grown on a type IV collagen matrix in vitro. Podocytes are the cells responsible for production of the alpha3/alpha4/alpha5 network  in vivo. BMSCs were able to express the alpha5 chain after infection with an adenoviral vector carrying an alpha5 transgene. In vivo , BMSCs consistently homed in the glomerular capillaries when directly infused into the kidney. These results indicate that BMSCs may be useful for gene therapy of Alport Syndrome.
