Generating mesenchymal stem-like cells (MSLCs) from induced pluripotent stem cells (iPSCs) can be a practical method for obtaining the sufficient cells for autologous tissue engineering. Single-cell culturing in specific medium and non-feeder cells is an alternative and promising strategy to overcome problems of embryo culture; however, little is known about how different culture media affect the proliferation and differentiation of MSLCs. We first derived MSLCs from iPSCs with non-integrating episomal plasmid vectors (hereafter 409B2 cells) using three different cell culture media, including single-cell culture medium in feeder-free condition: mTeSR1, DEF-CS500, or StemFit AK02N. The morphology of all MSLCs was completely altered to a fibroblastic morphology after four passages. Surface antigens CD29, CD44, CD73, CD90, but not CD34 and CD45, were expressed in all passages. RUNX2 was expressed in MSLCs cultured in all three feeder-free media, while SOX9 and PPARĪ³ were expressed in MSLCs cultured in only DEF-CS500. MSLCs derived from DEF-CS500, which is a single-cell culture medium, grew at a slightly faster rate than those cultured in other media and expressed early-stage genes for tri-lineage differentiation. Taken together, these findings provide valuable information for generating MSLCs using single-cell culture methods.
