AI Article Synopsis
- The study investigates how different culture systems affect the ability of induced pluripotent stem (iPS) cells to differentiate into hematopoietic stem/progenitor cells.
- Three culture systems were tested: E8, mTESR (both feeder-free mediums), and classical ES medium, with iPS cells co-cultured with OP9 cells for differentiation.
- The classical ES medium yielded a significantly higher differentiation efficiency of 28.4%, outperforming the E8 and mTESR systems.
Article Abstract
Objective: To investigate the in vitro effects of different culture systems on hematopoietic differentiation ability of induced pluripotent stem (iPS) cells.
Method: Two culture systems including E8 and mTESR(freeder-free medium), and the classical ES culture medium were chosen for culture of iPS cells. The iPS cells maintaining in above mentioning culcure systems were co-cultured with OP9 cells(murine bone marrow stromal cells) in vitro to be induced to differentiate into hematopoietic stem/progenitor cells. Flow cytometry and real-time quantitative PCR were used to detect the expression of specific hematopoietic markers and the effects of different culture systems on the differentiation of iPS in vitro.
Result: iPS cultured in the 3 selected medium could be differentiated into hematopoietic stem cells. Efficiency of hematopoietic differentiation was up to 28.4% in classical ES culture system, which was significantly higher than that in E8 and mTESR system.
Conclusion: Under the co-culture with OP9, iPS can differentiate into hematopoietic stem/progenitor cells, which shows higher efficiency when iPS maintained in the ES medium.
