Abstract (original English)

Mesenchymal stem cells (MSCs) have received considerable attention as therapeutic cells for regenerative medicine and tissue engineering, because of their ability to replace damaged cells or regenerate surrounding cells. There are many technical difficulties in the mass production of high-quality stem cells because the stem cells must maintain an efficient proliferative cell state during in vitro culture. The results of this study show that plasma surface-modification enhanced significantly the culture of adipose-derived mesenchymal stem cells (ASCs) on the polystyrene (PS) Petri dishes. Ar, O 2 , pyrrole, and 4,7,10-trioxa-1,13-tridecanediamine (TTDDA) were used as the gas and/or precursors for plasma modification. Specifically, surfaces of PS Petri dishes, coated with plasma polymerized pyrrole (ppPy) and plasma polymerized TTDDA (ppTTDDA) were found to contain amine and carboxyl functional groups, respectively. Ar and O 2 plasma-treated PS Petri dishes have similar culture abilities (±1.2 times) to commercially available tissue culture polystyrene (TCPS) dishes, and PS Petri dishes coated with ppPy and ppTTDDA have significantly enhanced culture abilities (2.4 times) at 96 hr compared with TCPS dishes. Western blotting was performed using antibodies against stem cell marker proteins to confirm the stemness properties of stem cells, in the sense that the expressions of the an
