Stem cell-based therapy has recently emerged
for use in novel therapeutics for incurable diseases. For
successful recovery from neurologic diseases, the most
pivotal factor is differentiation and directed neuronal cell
growth. In this study, we fabricated three different widths of
a micro-pattern on polydimethylsiloxane (PDMS; 1, 2, and
4 lm). Surface modification of the PDMS was investigated
for its capacity to manage proliferation and differentiation
of neural-like cells from umbilical cord blood-derived
mesenchymal stem cells (UCB-MSCs). Among the micropatterned
PDMS fabrications, the 1 lm-patterned PDMS
significantly increased cell proliferation and most of the cells
differentiated into neuronal cells. In addition, the 1 lmpatterned
PDMS induced an increase in cytosolic calcium,
while the differentiated cells on the flat and 4 lm-patterned
PDMS had no response. PDMS with a 1 lmpattern was also
aligned to direct orientation within 10 angles. Taken together,
micro-patterned PDMS supported UCB-MSC
proliferation and induced neural like-cell differentiation.
Our data suggest that micro-patterned PDMS might be a
guiding method for stem cell therapy that would improve its
therapeutic action in neurological diseases
