That eill willgive cytocompatability for MSCs, which may suggest compatability compatibilityfir fororger othercelks cellsas well. I would suggest differentiating the cells toward chondrogenic, osteogenic and adipogenic pathways. This will give more info on suitability of the scaffolfscaffol.
Yes. you could only test of suitability of MSCs to decellularized matrix. Other cells possibly contributing to the formation of the matrix by secreting extracellular matrix from the embryonic cells during embryonic development should be considered to fill the decellularzied matrix. Test with other cell phenotypes one by one. With these tested results, you could make a final combination ratios of the suitable cell phenotypes.
