Activation of Notch1 signalling promotes multi-lineage differentiation of c-Kit(POS)/NKX2.5(POS) bone marrow stem cells: implication in stem cell translational medicine.

ABSTRACT:

Introduction

Transplantation of bone marrow mesenchymal stem cells (BMSCs) can repair injured hearts. However, whether BMSC populations contain cells with cardiac stem cell characteristics is ill-defined. We report here that Notch signalling can promote differentiation of c-Kit(POS)/NKX2.5(POS) BMSCs into cardiomyocyte-like cells.

Methods

Total BMSCs were isolated from Sprague-Dawley rat femurs and c-Kit(POS) cells were purified. c-Kit(POS)/NKX2.5(POS) cells were isolated by single-cell cloning, and the presence of cardiomyocyte, smooth muscle cell (SMC), and endothelial cell differentiation markers assessed by immunofluorescence staining and semi-quantitative reverse-transcription polymerase chain reaction (RT-PCR) analysis. Levels of c-Kit and Notch1-4 in total BMSCs and c
