- bone differentiation began to be induced from the first day of induction of bone differentiation, and the longer the bone differentiation period, the stronger the bone differentiation occurred.
- bone differentiation is known to be less likely to occur in comparison with other mesenchymal stem cells in the conventional two-dimensional method. It was shown that bone differentiation is well done (Fig. 7).
- the conventional two-dimensional bone differentiation method takes about 2 to 5 weeks of bone differentiation of mesenchymal stem cells, but by placing a polymer membrane in a non-contact manner on a cell culture vessel and applying a hydrogel thereon to the mesenchyme thereon Using the three-dimensional bone differentiation method of the present invention inoculated with stem cells and incubated with bone differentiation pretreatment medium, it was confirmed that bone differentiation occurs in 3 to 7 days.
