Abstract
The present disclosure relates generally to an osteo-tissue graft capable of promoting bone tissue growth and regeneration, comprising at least one self-assemble peptide and mesenchymal stem cells (MSCs) in accordance with the present invention and a method of preparing such an osteo-tissue graft. The grafts are suitable for treatment of bone disorder or damages through tissue engineering, cellular replacement therapies as well as other applications.
Claims20
A 3-dimentional osteo-tissue graft comprising:
- live mesenchymal stem cells (MSCs), and
- ultrashort self-assembling peptide scaffolds.
A method to create a 3-dimentional osteo-tissue graft comprising:
- suspending MSCs in buffer solution;
- dissolving an ultrashort self-assembling peptide in buffer solution;
- loading a 3D bioprinter with the suspended MSCs and peptide solution;
- creating the 3-dimentional osteo-tissue graft using the 3D bioprinter or manually;
- incubating the 3-dimentional osteo-tissue graft for 5 min at 37° C.;
- culturing the 3-dimentional osteo-tissue graft in complete media and
- 3D culturing the MSCs by keeping the 3-dimentional osteo-tissue graft in osteogenic induction media or basal stem cell growth media.
