Abstract

Although the stem cells are commonly isolated by FACS or MACS, they are very expensive and these is no specific marker for liver stem/progentior cells (LSPCs). This paper applied a convenient and efficient method to enrich LSPCs. The fetal liver cells (FLCs) were firstly enriched by Percoll discontinuous gradient centrifugation (PDGC) from the rat fetal liver. Then the FLCs in culture were purified to be homogeneous in size by differential trypsinization and differential adherence (DTDA). Flow cytometric analysis revealed more than half of the purified FLCs expressed alternative markers of LSPCs (CD117, c-Met, Sca-1, CD90, CD49f and CD133). In other words, the purified FLCs were heterogeneous. Therefore, they were sequentially layered into six fractions by Percoll continuous gradient centrifugation (PCGC). Both CD133 and CD49f expressed decreasingly from fraction 1 to 6. In fraction 1 and 2, about 85% FLCs expressed CD133, which were revealed to be LSPCs by high expressions of AFP and CK-19, low expressions of G-6-P and ALB. To conclude, the purity of CD133+ LSPCs enriched by combination of PDGC, DTDA and PCGC is close to that obtained by MACS. This study will greatly contribute to two important biological aspects: liver stem cells isolation and liver cell therapy.
