Catharmus tinctorius volatile oil promote the migration of mesenchymal stem cells via ROCK2/Myosin light chain signaling.

MSC transplantation has been explored as a new clinical approach to stem cell-based therapies for bone diseases in regenerative medicine due to their osteogenic capability. However, only a small population of implanted MSC could successfully reach the injured areas. Therefore, enhancing MSC migration could be a beneficial strategy to improve the therapeutic potential of cell transplantation.

[Sequentially inducting murine embryonic stem cells into hematopoietic stem cells in vitro by hematopoietic development procedure for reconstitution of hematopoiesis in vivo].

This study was purposed to directly induce murine embryonic stem cells (ESC) into hematopoietic stem cells (HSC) by simulating the spatial and temporal hematopoietic microenvironment changes in embryonic development, and to investigate the function of in vivo hematopoietic reconstitution of these HSC. E14 ESC were induced into embryoid body (EB) firstly. Then the cells from EB were further co-cultured with human aorta-gonad-mesonephros (AGM) region, fetal liver (FL) and bone marrow (BM) stromal cells in Transwell non-contact system in sequential orders.

[Effects of human aorta-gonad-mesonephros region stromal cells on inducing differentiation of murine embryonic stem cells into hematopoietic stem/progenitor cells in vitro].

This study was aimed to investigate the effect of human aorta-gonad-mesonephros (AGM) region stromal cells on differentiation of murine embryonic stem cells (ESC) into hematopoietic stem cells (HSC) in vitro and to clarify their effect mechanism. E14 murine ESC were induced into embryo body (EB) firstly. Then the EB cells were further co-cultured with the stromal cells from human AGM region, fetal liver (FL) or bone marrow (BM) in Transwell non-contact system.
