Abstract: The aim of this study was to study the isolatation,culture,identification and multi-lineage differentiation potential of liver mesenchymal stem cells (LMSCs) in Beijing duck.LMSCs were isolated from 19-day-old healthy Beijing duck embryos by enzymatic digestion and cultured in vitro.The specific markers (CD29,CD44,CD71,CD73,CD90,CD105,CD133 and CD166) of LMSCs were detected by immunofluorescence,RT-PCR and flow cytometry.Because the LMSCs were mixed with some hematopoietic stem cells,CD31 and CD34 which were the specific markers of hematopoietic stem cells were detected.Furthermore,LMSCs were induced to differentiate into adipogenic and osteogenic cells to detect their multi-lineage differentiation potential.The results showed that LMSCs obtained by enzymatic digestion expressed specific markers of mesenchymal stem cells,and the specific markers of hematopoietic stem cells were negative.It was proved that LMSCs were hepatic mesenchymal stem cells,and differentiated into adipocytes and osteoblasts.RT-PCR detection results revealed that adipogenic cells expressed peroxisome proliferator-activated receptor γ (PPAR-γ) and lipoprotein lipase (LPL),osteogenic cells expressed Collogen Ⅰ and Runt-related transcription factor 2 (RUNX2).The strong self-proliferation ability of Beijing duck LMSCs made it possible to make unlimited use of livestock and poultry genetic resources.The strong multi-directional differentiation potential indicated that the level of reprogramming was low,and it had great advantages for the recovery of livestock and poultry germplasm resources.It provided a theoretical basis for tissue regeneration research and opened up a broader platform for the development and utilization of livestock and poultry resources.
