Our research utilized two cell lines carrying a bisatellite microchromosome originated from two normal phenotypic families found by Professor Jiahui Xia to make the BM become a new vector for gene therapy. The research will finally establish a novel vector that can be steadily transmitted, has enough capacity to carry foreign genes, has no harm to human being, has no immunogenecity and is easy to transfer. This research can provide brand new vector tool for gene therapy of human hereditary diseases and tumors.
