RESUMO
<p><b>OBJECTIVE</b>To establish immortalized lymphoblastoid cell lines of a Miao core pedigree with Bardet-Biedl syndrome (BBS), in order to provide a long-term source of material for research.</p><p><b>METHODS</b>With Epstein-Barr virus transformation of B cells and addition of cyclosporine A to inhibit the activity of T cells, fresh anticoagulated blood samples with heparin were collected from 12 members of the core pedigree, and were used to establish the immortalized lymphoblastoid cell lines of B lymphocytes.</p><p><b>RESULTS</b>Twelve immortalized lymphoblastoid cell lines of the core BBS pedigree were obtained successfully.</p><p><b>CONCLUSION</b>The immortalized B lymphoblastoid cell lines of the Miao pedigree with BBS can preserve the whole genome information and provide long-term research materials for BBS study.</p>
