The uni­form seed­ing of the cells in a scaf­fold does not neces­sar­ily reflect nat­ive tis­sue con­di­tions. In order to provide proper func­tion­ing of the engin­eered tis­sue, spa­tially cell/ECM pat­terned con­structs are often required. In the offered here study we are aim­ing to develop a bio-acous­tic lev­it­a­tional assembly (BAL) tech­no­logy for a pat­terned cell-seed­ing in 3D scaf­folds, employ­ing ultra­sound stand­ing waves, which has been pre­vi­ously described by our col­lab­or­at­ors from Lyon. Addi­tion­ally, the BAL tech­nique will be com­bined with our Focused Low-Intens­ity Pulsed Ultra­sound (FLIPUS) in-vitro set-up for spa­tial- and time-con­trolled release of growth factors enhan­cing tis­sue regen­er­a­tion pro­cess. The suc­cess­ful pat­tern­ing of the 3D scaf­fold will be fur­ther visu­al­ized by high-fre­quency ultra­sound and mul­ti­photon con­focal micro­scopy. Bio­chem­ical assays are to be per­formed to eval­u­ate cel­lu­lar activ­it­ies and effic­acy of the released growth factor.

The pro­ject’s agenda will include:

• Build­ing a BAL set-up
• Optim­iz­a­tion of the assembly acous­tic para­met­ers
• Optim­iz­a­tion of FLIPUS acous­tic para­met­ers
• Mat­lab pro­gram­ming

Some know­ledge in bio­chem­istry and tis­sue cell cul­ture is favor­able, but not required.

We are a mul­tina­tional team of inter­dis­cip­lin­ary sci­ent­ists, work­ing on novel mus­cu­lo­skeletal tis­sue ima­ging and regen­er­a­tion approaches. For this chal­len­ging study, we would like to have a Mas­ter Stu­dent who has strong engin­eer­ing and/or phys­ics back­ground and is excited to work on clin­ic­ally sig­ni­fic­ant pro­jects.
