Nous rapportons ici le développement d&#39;un nouveau procédé d&#39;immortalisation de lymphocytes B humains à partir de sang total par lyse des globules rouges et la viabilité cellulaire établie de B-LCL a été évaluée par le test MTT. Les résultats ont montré que la viabilité des cellules B-LCL établies par la méthode de la lyse des globules rouges est beaucoup plus élevé que celui du procédé de séparation par gradient de densité. L&#39;avantage majeur de la méthode de la lyse des globules rouges ...

Resting B cells could be transformed by the Epstein-Barr virus (EBV) in vitro into actively proliferating B lymphoblastoid cell lines (B-LCLs). B-LCLs are similar to germ cells in differentiation and development, and the somatic mutation rate of B-LCLs was only 0.3%1, with negligible genetic and phenotypic alteration. Therefore, B-LCLs, as surrogates for peripheral blood mononuclear cells (PBMCs), have substantially accelerated the progress of genomics, transcriptomics and proteomics study of EBV associated diseases2,3. Moreover, B-LCLs also have important application in screening monoclonal antibodies4,5. 
Several methods have been developed for the immortalization of B lymphocytes by EBV. The most major common procedures include the isolation of B lymphocytes and the use of B95-8 cell lines to produce infectious EBV. From isolation to transformation, these methods are divided into three strategies. Lymphocytes are separated from fresh blood by density gradient centrifugation and EBV transformation directly6-8, named density gradient separation method in this study. However, other techniques overcome the difficulty of shipping fresh blood and use a procedure for freezing purified lymphocytes and subsequent thawing and EBV infection9-11. Cryopreserved whole blood can also be used for the isolation of B lymphocytes and transformation12,13. In addition to density gradient centrifugation to separate B lymphocytes, some researchers use a magnetic cell sorter to select B lymphocytes12. However, magnetic separation is an expensive, complex and time consuming process. Although these methods are useful to immortalize B lymphocytes with a high success rate, the need to treat a large number of clinical samples and the relatively small volume of blood require a simpler method for the establishment of a permanent cell line.
Another less commonly used method is using whole blood as the source of nucleated cells for EBV infection and the establishment of B-LCLs. These methods simplify the technique by omitting the separation procedure. Only a small amount of whole blood, either fresh14 or frozen15,16, is sufficient to obtain the cell lines. Unfortunately, there is great variability in success from documents15,16 and several of our validation tests. Furthermore, transformed colonies are hardly recognized under a microscope because of the large contaminating impurities. Thus, a more reliable method for transformation is required.
Based on the above considerations, we have developed a novel method to establish B-LCLs without previous purification of the lymphocytes, named the red blood cell lysis method. This method is convenient, time saving and applicable to a large number of samples. As little as 0.5 mL of whole blood was enough to obtain B-LCLs that are easily obtainable from infants and the elderly without significantly harming their health.

a simple red blood cell lysis method for the establishment of b lymphoblastoid cell lines

A number of methods exist for the transformation of B lymphocytes by the Epstein Barr virus in vitro into immortalized cell lines. We have developed a new method with a powerful and simple strategy for the establishment of B-LCLs, the red blood cell lysis method. This method simplified the PBMC separation procedure with red blood cell removal, and used as little as 0.5 mL of whole blood for establishing EBV-immortalized cell lines, which can proliferate to large cell numbers in a relatively short amount time with a 100% success rate. The method is simple, reliable, time saving, and applicable to treating a large number of the clinical samples.

Au cours du processus de transformation, les changements morphologiques des cellules sont visualisées par microscopie optique (Figure 2). De petites grappes de cellules étaient clairement visibles par le procédé de séparation par gradient de densité au bout de 7 jours après l&#39;infection, alors que seule une couche épaisse de fragments cellulaires sont visibles à partir de la méthode de la lyse des globules rouges. Cependant, des amas de cellules lymphoblasto...
